Straight Line Ceramics Variety Through a Repeating Art Element Ceramics

Line

A line is defined as a mark that connects the infinite between two points, taking any form along the way.

Learning Objectives

Compare and contrast different uses of line in fine art

Key Takeaways

Key Points

• Actual lines are lines that are physically present, existing as solid connections between one or more points.
• Unsaid line refers to the path that the viewer 's eye takes as it follows shapes, colors, and forms forth whatever given path.
• Straight or archetype lines provide stability and structure to a limerick and can be vertical, horizontal, or diagonal on a work's surface.
• Expressive lines refer to curved marks that increase the sense of dynamism of a work of art.
• The outline or contour lines create a edge or path around the border of a shape, thereby outlining and defining information technology. "Cross profile lines" delineate differences in the features of a surface.
• Hatch lines are a series of curt lines repeated in intervals, typically in a single direction, and are used to add shading and texture to surfaces, while cantankerous-hatch lines provide additional texture and tone to the image surface and tin can be oriented in any management.

Key Terms

• texture:The feel or shape of a surface or substance; the smoothness, roughness, softness, etc. of something.
• cross-hatching:A method of showing shading past ways of multiple small lines that intersect.
• line:A path through ii or more points.

The line is an essential element of art, defined as a mark that connects the space between ii points, taking any form along the way. Lines are used virtually often to ascertain shape in two-dimensional works and could be chosen the nigh ancient, too every bit the most universal, forms of mark making.

There are many dissimilar types of lines, all characterized by their lengths being greater than their width, likewise as by the paths that they accept. Depending on how they are used, lines assistance to determine the movement, direction, and free energy of a work of art. The quality of a line refers to the graphic symbol that is presented by a line in order to animate a surface to varying degrees.

Bodily lines are lines that are physically nowadays, existing as solid connections between one or more points, while implied lines refer to the path that the viewer's middle takes as information technology follows shape, color, and class within an art work. Implied lines requite works of art a sense of motility and keep the viewer engaged in a composition. We tin see numerous implied lines in Jacques-Louis David's Oath of the Horatii, connecting the figures and deportment of the piece by leading the middle of the viewer through the unfolding drama.

Jacques-Louis David, Oath of the Horatii, 1784: Many implied lines connect the figures and action of the piece past leading the eye of the viewer through the unfolding drama.

Direct or classic lines add together stability and structure to a composition and can be vertical, horizontal, or diagonal on the surface of the work. Expressive lines refer to curved marks that increment the sense of dynamism of a piece of work of art. These types of lines often follow an undetermined path of sinuous curves. The outline or contour lines create a border or path around the border of a shape, thereby outlining and defining information technology. Cantankerous contour lines delineate differences in the features of a surface and tin can give the illusion of three dimensions or a sense of form or shading.

Hatch lines are a series of short lines repeated in intervals, typically in a unmarried management, and are used to add together shading and texture to surfaces. Cantankerous-hatch lines provide boosted texture and tone to the paradigm surface and can exist oriented in whatsoever direction. Layers of cross-hatching can add together rich texture and book to image surfaces.

Light and Value

Value refers to the use of light and dark in art.

Learning Objectives

Explain the artistic use of low-cal and nighttime (as well known equally "value")

Key Takeaways

Fundamental Points

• In painting, value changes are accomplished by adding black or white to a color.
• Value in fine art is also sometimes referred to as " tint " for low-cal hues and "shade" for dark hues.
• Values near the lighter end of the spectrum are termed "high-keyed" while those on the darker stop are called "low-keyed."
• In two-dimensional art works, the apply of value can aid to give a shape the illusion of mass or volume .
• Chiaroscuro was a common technique in Baroque painting and refers to clear tonal contrasts exemplified by very loftier-keyed whites, placed directly confronting very depression-keyed darks.

Key Terms

• chiaroscuro:An artistic technique popularized during the Renaissance, referring to the utilize of exaggerated calorie-free contrasts in order to create the illusion of volume.

The utilise of light and dark in fine art is called value. Value can be subdivided into tint (light hues) and shade (dark hues). In painting, which uses subtractive color, value changes are achieved by calculation black or white to a colour. Artists may also employ shading, which refers to a more than subtle manipulation of value. The value calibration is used to testify the standard variations in tones . Values near the lighter terminate of the spectrum are termed high-keyed, while those on the darker end are depression-keyed.

Value scale: The value scale represents different degrees of light used in artwork.

In two-dimensional artworks, the apply of value can help to give a shape the illusion of mass or book. It will also give the entire composition a sense of lighting. Loftier contrast refers to the placing of lighter areas straight against much darker ones, and then their divergence is showcased, creating a dramatic upshot. Loftier contrast also refers to the presence of more blacks than white or greyness. Low-contrast images consequence from placing mid-range values together and so in that location is non much visible difference between them, creating a more subtle mood.

In Bizarre painting, the technique of chiaroscuro was used to produce highly dramatic effects in fine art. Chiaroscuro, which means literally "light-dark" in Italian, refers to clear tonal contrasts exemplified by very high-keyed whites, placed directly against very low-keyed darks. Candlelit scenes were common in Bizarre painting as they effectively produced this dramatic blazon of event. Caravaggio used a high contrast palette in such works as The Denial of St. Peter to create his expressive chiaroscuro scene.

Caravaggio, The Deprival of St. Peter, 1610: Caravaggio'due south The Deprival of St. Peter is an excellent example of how calorie-free tin be manipulated in artwork.

Color

In the visual arts, color theory is a body of practical guidance to color mixing and the visual impacts of specific colour combinations.

Learning Objectives

Limited the most important elements of colour theory and artists' use of color

Key Takeaways

Key Points

• Colour theory starting time appeared in the 17th century, when Isaac Newton discovered that white lite could be passed through a prism and divided into the full spectrum of colors.
• The spectrum of colors independent in white light are ruby, orange, yellow, green, blue, indigo , and violet.
• Color theory divides color into the " primary colors " of red, yellow, and blue, which cannot be mixed from other pigments, and the "secondary colors" of light-green, orange, and violet, which result from different combinations of the primary colors.
• Primary and secondary colors are combined in diverse mixtures to create third colors.
• Complementary colors are constitute opposite each other on the colour cycle and correspond the strongest contrast for those detail two colors.

Key Terms

• complementary colour:A color which is regarded every bit the reverse of another on the color bicycle (i.e., ruby-red and greenish, yellow and regal, and orange and blue).
• value:The relative darkness or lightness of a color in a specific area of a painting or other visual art.
• primary color:Whatever of iii colors which, when added to or subtracted from others in different amounts, can generate all other colors.
• tint:A color considered with reference to other very similar colors. Red and blue are different colors, but ii shades of crimson are different tints.
• gradation:A passing by small degrees from one tone or shade, as of color, to another.
• hue:A color, or shade of color.

Colour is a key artistic element which refers to the use of hue in art and design. It is the nearly circuitous of the elements considering of the broad array of combinations inherent to it. Color theory first appeared in the 17th century when Isaac Newton discovered that white light could be passed through a prism and divided into the full spectrum of colors. The spectrum of colors contained in white calorie-free are, in order: cherry, orange, xanthous, green, blue, indigo and violet.

Color theory subdivides color into the "main colors" of red, yellow, and blue, which cannot exist mixed from other pigments; and the "secondary colors" of dark-green, orange and violet, which result from dissimilar combinations of the primary colors. Primary and secondary colors are combined in diverse mixtures to create "tertiary colors." Color theory is centered around the color wheel, a diagram that shows the relationship of the various colors to each other .

Color wheel: The color cycle is a diagram that shows the relationship of the various colors to each other.

Color " value " refers to the relative lightness or darkness of a color. In addition, "tint" and "shade" are important aspects of color theory and result from lighter and darker variations in value, respectively. "Tone" refers to the gradation or subtle changes of a color on a lighter or darker calibration. "Saturation" refers to the intensity of a color.

Condiment and Subtractive Color

Additive color is color created by mixing red, dark-green, and bluish lights. Television screens, for example, apply additive color equally they are made upwards of the master colors of red, blue and green (RGB). Subtractive color,  or "process color," works every bit the reverse of additive color and the principal colors become cyan, magenta, xanthous, and black (CMYK). Common applications of subtractive color can be found in printing and photography.

Complementary Color

Complementary colors tin be establish directly opposite each other on the color wheel (purple and yellow, green and red, orange and blue). When placed next to each other, these pairs create the strongest contrast for those item two colors.

Warm and Absurd Colour

The distinction betwixt warm and absurd colors has been important since at least the tardily 18th century. The contrast, as traced by etymologies in the Oxford English language Dictionary, seems related to the observed contrast in landscape light, between the "warm" colors associated with daylight or sunset and the "cool" colors associated with a grayness or overcast twenty-four hour period. Warm colors are the hues from red through yellow, browns and tans included. Cool colors, on the other hand, are the hues from blue green through bluish violet, with about grays included. Colour theory has described perceptual and psychological effects to this dissimilarity. Warm colors are said to advance or appear more active in a painting, while cool colors tend to recede. Used in interior design or manner, warm colors are said to agitate or stimulate the viewer , while cool colors at-home and relax.

Texture

Texture refers to the tactile quality of the surface of an art object.

Learning Objectives

Recognize the use of texture in art

Fundamental Takeaways

Key Points

• Visual texture refers to an implied sense of texture that the artist creates through the use of diverse creative elements such as line , shading, and color.
• Bodily texture refers to the physical rendering or the real surface qualities we tin notice by touching an object.
• Visible brushstrokes and dissimilar amounts of pigment will create a physical texture that can add to the expressiveness of a painting and draw attention to specific areas within information technology.
• It is possible for an artwork to incorporate numerous visual textures but however remain smooth to the touch.

Key Terms

• tactile:Tangible; perceptible to the sense of touch.

Texture

Texture in art stimulates the senses of sight and touch and refers to the tactile quality of the surface of the art. It is based on the perceived texture of the canvas or surface, which includes the application of the pigment. In the context of artwork, there are 2 types of texture: visual and actual. Visual texture refers to an implied sense of texture that the artist creates through the utilize of diverse artistic elements such as line, shading and color. Bodily texture refers to the physical rendering or the existent surface qualities we can observe by touching an object, such as paint application or three-dimensional fine art.

It is possible for an artwork to contain numerous visual textures, yet nevertheless remain smooth to the bear upon. Take for example Realist or Illusionist works, which rely on the heavy use of pigment and varnish, yet maintain an utterly smooth surface. In Jan Van Eyck'south painting "The Virgin of Chancellor Rolin" we can notice a slap-up deal of texture in the article of clothing and robes especially, while the surface of the work remains very smooth .

Jan van Eyck, The Virgin of Chancellor Rolin, 1435: The Virgin of Chancellor Rolin has a great deal of texture in the clothing and robes, but the actual surface of the work is very smooth.

Paintings oftentimes utilise bodily texture besides, which nosotros tin can observe in the physical awarding of paint. Visible brushstrokes and different amounts of paint will create a texture that adds to the expressiveness of a painting and draw attention to specific areas inside it. The creative person Vincent van Gogh is known to have used a great bargain of actual texture in his paintings, noticeable in the thick application of paint in such paintings as Starry Night.

Vincent van Gogh, The Starry Dark, 1889: The Starry Dark contains a great bargain of actual texture through the thick application of paint.

Shape and Volume

Shape refers to an area in a two-dimensional space that is defined by edges; book is three-dimensional, exhibiting superlative, width, and depth.

Learning Objectives

Define shape and volume and identify means they are represented in fine art

Key Takeaways

Key Points

• "Positive space " refers to the space of the defined shape or effigy.
• "Negative space" refers to the infinite that exists around and between i or more shapes.
• A " airplane " in fine art refers to any surface expanse within space.
• " Form " is a concept that is related to shape and can be created by combining two or more shapes, resulting in a three-dimensional shape.
• Art makes use of both actual and implied volume .
• Shape, volume, and space, whether actual or implied, are the ground of the perception of reality.

Cardinal Terms

• form:The shape or visible construction of an artistic expression.
• volume:A unit of three-dimensional measure of infinite that comprises a length, a width, and a peak.
• plane:A flat surface extending infinitely in all directions (due east.g., horizontal or vertical plane).

Shape refers to an surface area in ii-dimensional space that is defined by edges. Shapes are, past definition, ever flat in nature and can exist geometric (eastward.1000., a circle, square, or pyramid) or organic (due east.g., a leaf or a chair). Shapes can be created by placing ii different textures , or shape-groups, next to each other, thereby creating an enclosed area, such every bit a painting of an object floating in water.

"Positive infinite" refers to the space of the divers shape, or figure. Typically, the positive space is the subject of an artwork. "Negative space" refers to the infinite that exists around and between i or more shapes. Positive and negative space can go difficult to distinguish from each other in more abstruse works.

A "aeroplane" refers to any surface expanse within space. In two-dimensional fine art, the " picture plane " is the apartment surface that the image is created upon, such as newspaper, canvas, or wood. 3-dimensional figures may be depicted on the flat motion-picture show plane through the use of the artistic elements to imply depth and book, as seen in the painting Small Boutonniere of Flowers in a Ceramic Vase past Jan Brueghel the Elder.

Jan Brueghel the Elder, Modest Bouquet of Flowers in a Ceramic Vase, 1599: Three-dimensional figures may be depicted on the flat picture airplane through the use of the artistic elements to imply depth and book.

"Form" is a concept that is related to shape. Combining ii or more shapes tin can create a three-dimensional shape. Course is always considered three-dimensional equally it exhibits book—or height, width, and depth. Art makes employ of both bodily and unsaid volume.

While iii-dimensional forms, such equally sculpture, accept volume inherently, volume can likewise be imitation, or implied, in a 2-dimensional work such equally a painting. Shape, volume, and space—whether actual or implied—are the basis of the perception of reality.

Time and Motion

Move, a principle of art, is a tool artists use to organize the artistic elements in a work; it is employed in both static and fourth dimension-based mediums.

Learning Objectives

Name some techniques and mediums used by artists to convey motion in both static and time-based art forms

Key Takeaways

Key Points

• Techniques such as scale and proportion are used to create the feeling of motion or the passing of time in static a visual piece.
• The placement of a repeated element in different surface area within an artwork is another way to imply move and the passing of time.
• Visual experiments in fourth dimension and motility were first produced in the mid-19th century, and the photographer Eadweard Muybridge is well-known for his sequential shots.
• The time-based mediums of film, video, kinetic sculpture , and performance art utilise time and motility by their very definitions.

Key Terms

• frames per second:The number of times an imaging device produces unique sequent images (frames) in one 2nd. Abridgement: FPS.
• static:Fixed in place; having no motion.

Motion, or movement, is considered to exist ane of the "principles of art"; that is, one of the tools artists use to organize the creative elements in a piece of work of art. Motion is employed in both static and in time-based mediums and can show a straight action or the intended path for the viewer 's heart to follow through a piece.

Techniques such every bit calibration and proportion are used to create the feeling of motility or the passing of time in static visual artwork. For example, on a flat picture plane , an image that is smaller and lighter colored than its environment will appear to exist in the background. Another technique for implying motility and/or time is the placement of a repeated element in different areas inside an artwork.

Visual experiments in time and motion were first produced in the mid-19th century. The lensman Eadweard Muybridge is well known for his sequential shots of humans and animals walking, running, and jumping, which he displayed together to illustrate the motion of his subjects. Marcel Duchamp's Nude Descending a Staircase, No. 2 exemplifies an absolute feeling of motion from the upper left to lower right corner of the slice.

Marcel Duchamp, Nude Descending a Staircase, No. 2, 1912: This piece of work represents Duchamp's conception of motion and time.

While static fine art forms have the power to imply or advise time and motion, the time-based mediums of motion picture, video, kinetic sculpture, and performance art demonstrate time and move by their very definitions. Film is many static images that are apace passed through a lens. Video is substantially the aforementioned process, simply digitally-based and with fewer frames per second . Performance art takes place in existent time and makes apply of existent people and objects, much like theater. Kinetic fine art is fine art that moves, or depends on motility, for its effect. All of these mediums use time and movement as a central attribute of their forms of expression.

Chance, Improvisation, and Spontaneity

Dadaism, Surrealism, and the Fluxus move all relied on the elements of chance, improvisation, and spontaneity every bit tools for making fine art works.

Learning Objectives

Describe how Dadaism, Surrealism, and the Fluxus movement relied on chance, improvisation, and spontaneity

Primal Takeaways

Key Points

• Dadaists are known for their "automatic writing" or stream of consciousness writing, which highlights the creativity of the unconscious mind.
• Surrealist works, much like Dadaist works, ofttimes feature an element of surprise, unexpected juxtaposition , and tapping into the unconscious mind.
• Surrealists are known for having invented " exquisite corpse" drawing.
• The Fluxus movement was known for its " happenings ," which were performance events or situations that could take place anywhere, in any course , and relied heavily on chance, improvisation, and audition participation.

Key Terms

• happening:A spontaneous or improvised consequence, specially one that involves audition participation.
• assemblage:A drove of things which have been gathered together..

Chance, improvisation, and spontaneity are elements that can be used to create fine art, or they can be the very purpose of the artwork itself. Whatever medium tin apply these elements at any betoken within the artistic procedure.

Marcel Duchamp, Urinal, 1917: Marcel Duchamp'south Urinal is an example of a "fix-made," which were objects that were purchased or found so declared art.

Dadaism

Dadaism was an art move popular in Europe in the early 20th century. It was started by artists and poets in Zurich, Switzerland with strong anti-state of war and left-leaning sentiments. The movement rejected logic and reason and instead prized irrationality, nonsense, and intuition. Marcel Duchamp was a dominant member of the Dadaist movement, known for exhibiting "ready-mades," which were objects that were purchased or found and so declared art.

Dadaists used what was readily bachelor to create what was termed an "assemblage," using items such as photographs, trash, stickers, bus passes, and notes. The piece of work of the Dadaists involved chance, improvisation, and spontaneity to create art. They are known for using "automatic writing" or stream of consciousness writing, which ofttimes took nonsensical forms, but allowed for the opportunity of potentially surprising juxtapositions and unconscious creativity.

Surrealism

The Surrealist movement, which developed out of Dadaism primarily as a political movement, featured an chemical element of surprise, unexpected juxtaposition and the tapping of the unconscious mind. Andre Breton, an important member of the movement, wrote the Surrealist manifesto, defining it equally follows:

"Surrealism, n. Pure psychic automatism , past which one proposes to express, either verbally, in writing, or by whatsoever other manner, the real functioning of thought. Dictation of thought in the absenteeism of all command exercised past reason, outside of all aesthetic and moral preoccupation. "

Like Dadaism before it, the Surrealist movement stressed the unimportance of reason and planning and instead relied heavily upon chance and surprise every bit a tool to harness the inventiveness of the unconscious heed. Surrealists are known for having invented "exquisite corpse" drawing, an exercise where words and images are collaboratively assembled, one later some other. Many Surrealist techniques, including exquisite corpse drawing, allowed for the playful creation of art through assigning value to spontaneous production.

The Fluxus motion

The Fluxus move of the 1960s was highly influenced by Dadaism. Fluxus was an international network of artists that skillfully composite together many dissimilar disciplines, and whose work was characterized by the utilise of an farthermost do-it-yourself (DIY) aesthetic and heavily intermedia artworks. In addition, Fluxus was known for its "happenings," which were multi-disciplinary performance events or situations that could take place anywhere. Audience participation was essential in a happening, and therefore relied on a bully deal of surprise and improvisation. Key elements of happenings were often planned, but artists left room for improvisation, which eliminated the purlieus between the artwork and the viewer , thus making the audience an important part of the art.

Inclusion of All Five Senses

The inclusion of the five human senses in a single work takes place most frequently in installation and functioning art.

Learning Objectives

Explain how installation and performance art include the five senses of the viewer

Key Takeaways

Key Points

• In contemporary art, it is quite common for work to cater to the senses of sight, touch, and hearing, while it is somewhat less mutual to address smell and taste.
• "Gesamtkunstwerk," or "total piece of work of art," is a German word that refers to an artwork that attempts to address all 5 human senses.
• Installation art is a genre of three-dimensional artwork that is designed to transform the viewer 's perception of a infinite .
• Virtual reality is a term that refers to computer-false environments.

Fundamental Terms

• happening:A spontaneous or improvised event, especially one that involves audience participation.
• virtual reality:A reality based in the calculator.

The inclusion of the five human senses in a single piece of work takes identify most frequently in installation and performance-based art. In addition, works that strive to include all senses at in one case generally make use of some form of interactivity, equally the sense of taste clearly must involve the participation of the viewer. Historically, this attending to all senses was reserved to ritual and ceremony . In contemporary art, it is quite mutual for work to cater to the senses of sight, bear on, and hearing, while somewhat less mutual for art to address the senses of smell and taste.

The German word "Gesamtkunstwerk," meaning "total work of art," refers to a genre of artwork that attempts to address all 5 man senses. The concept was brought to prominence by the German opera composer Richard Wagner in 1849. Wagner staged an opera that sought to unite the art forms, which he felt had become overly disparate. Wagner's operas paid great attention to every detail in lodge to accomplish a state of total artistic immersion. "Gesamkunstwerk" is now an accustomed English language term relating to aesthetics , just has evolved from Wagner'due south definition to mean the inclusion of the five senses in art.

Installation fine art is a genre of three-dimensional artwork that is designed to transform the viewer'southward perception of a space. Embankment by Rachel Whiteread exemplifies this blazon of transformation. The term generally pertains to an interior space, while Land Art typically refers to an outdoor space, though at that place is some overlap between these terms. The Fluxus movement of the 1960s is key to the evolution of installation and functioning art equally mediums.

Rachel Whiteread, Embankment, 2005: Whiteread's installation Embankment is a type of art designed to transform the viewer'due south perception of space.

"Virtual reality" is a term that refers to estimator-imitation environments. Currently, most virtual reality environments are visual experiences, but some simulations include additional sensory information. Immersive virtual reality has developed in recent years with the improvement of technology and is increasingly addressing the 5 senses within a virtual realm. Artists have been exploring the possibilities of these fake and virtual realities with the expansion of the field of study of cyberarts, though what constitutes cyberart continues to be upward for fence. Environments such as the virtual world of 2nd Life are more often than not accepted, simply whether or not video games should be considered fine art remains undecided.

Compositional Balance

Compositional balance refers to the placement of the creative elements in relation to each other within a work of art.

Learning Objectives

Categorize the elements of compositional balance in a piece of work of art

Key Takeaways

Key Points

• A harmonious compositional balance involves arranging elements and then that no one part of a work overpowers or seems heavier than any other part.
• The three most common types of compositional rest are symmetrical, asymmetrical, and radial .
• When balanced, a composition appears stable and visually right. Just as symmetry relates to aesthetic preference and reflects an intuitive sense for how things "should" appear, the overall remainder of a given composition contributes to outside judgments of the work.

Key Terms

• radial:Arranged like rays that radiate from, or converge to, a common middle.
• symmetry:Exact correspondence on either side of a dividing line, plane, centre, or axis. The satisfying arrangement of a balanced distribution of the elements of a whole.
• asymmetry:Want of symmetry, or proportion between the parts of a thing, especially want of bilateral symmetry. Lacking a common measure out between two objects or quantities; Incommensurability. That which causes something to not be symmetrical.

Compositional rest refers to the placement of the elements of art (color, form , line , shape, space , texture , and value) in relation to each other. When balanced, a composition appears more stable and visually pleasing. Simply every bit symmetry relates to aesthetic preference and reflects an intuitive sense for how things "should" appear, the overall balance of a given limerick contributes to outside judgments of the work.

Creating a harmonious compositional balance involves arranging elements and then that no unmarried part of a work overpowers or seems heavier than any other part. The three near common types of compositional balance are symmetrical, asymmetrical, and radial.

Compositional residual: The 3 mutual types of residuum are symmetric, asymmetric, and radial.

Symmetrical residual is the most stable, in a visual sense, and by and large conveys a sense of harmonious or aesthetically pleasing proportionality. When both sides of an artwork on either side of the horizontal or vertical centrality of the picture airplane are the same in terms of the sense that is created by the organization of the elements of art, the work is said to showroom this type of balance. The contrary of symmetry is asymmetry .

Leonardo da Vinci, Vitruvian Man, 1487: Leonardo da Vinci's Vitruvian Man is often used as a representation of symmetry in the human being body and, past extension, the natural universe.

Asymmetry is defined as the absence of, or a violation of, the principles of symmetry. Examples of asymmetry appear commonly in architecture. Although pre-modern architectural styles tended to place an accent on symmetry (except where extreme site conditions or historical developments lead away from this classical ideal), modern and postmodern architects frequently used disproportion as a design element. For instance, while most bridges use a symmetrical form due to intrinsic simplicities of blueprint, assay, fabrication, and economical employ of materials, a number of modern bridges have deliberately departed from this, either in response to site-specific considerations or to create a dramatic blueprint argument. .

Oakland Bay Bridge: Eastern bridge replacement of the San Francisco–Oakland Bay Span reflects asymmetrical architectural blueprint.

Radial remainder refers to circular elements in compositions. In classical geometry, a radius of a circle or sphere is any line segment from its eye to its perimeter. By extension, the radius of a circle or sphere is the length of any such segment, which is half the diameter. The radius may be more than half the diameter, which is commonly defined equally the maximum distance between any two points of the figure. The inradius of a geometric figure is unremarkably the radius of the largest circle or sphere contained in information technology. The inner radius of a ring, tube or other hollow object is the radius of its cavity. The proper noun "radial" or "radius" comes from Latin radius, meaning "ray" merely likewise the spoke of a circular chariot wheel.

Rhythm

Artists use rhythm every bit a tool to guide the heart of the viewer through works of art.

Learning Objectives

Recognize and translate the use of rhythm in a piece of work of art

Fundamental Takeaways

Key Points

• Rhythm may be generally defined every bit a "movement marked by the regulated succession of strong and weak elements, or of opposite or different conditions" (Betimes. 1971).
• Rhythm may also refer to visual presentation equally "timed motion through infinite " (Jirousek 1995), and a common linguistic communication of blueprint unites rhythm with geometry.
• For instance, placing a blood-red spiral at the lesser left and top right, for case, will cause the middle to motility from one spiral, to the other, and everything in betwixt. It is indicating movement in the piece by the repetition of elements and, therefore, can brand artwork seem active.

Key Terms

• symmetry:Exact correspondence on either side of a dividing line, plane, center or axis. The satisfying system of a balanced distribution of the elements of a whole.

The principles of visual art are the rules, tools, and guidelines that artists use to organize the elements of in a piece of artwork. When the principles and elements are successfully combined, they assist in creating an aesthetically pleasing or interesting work of fine art. While at that place is some variation among them, motility, unity, harmony, variety, rest, rhythm, emphasis, contrast , proportion, and pattern are unremarkably sited as principles of art.

Rhythm (from Greek rhythmos, "any regular recurring movement, symmetry " (Liddell and Scott 1996)) may exist by and large divers as a "movement marked by the regulated succession of potent and weak elements, or of opposite or different conditions" (Anon. 1971). This general pregnant of regular recurrence or pattern in fourth dimension may exist applied to a wide variety of cyclical natural phenomena having a periodicity or frequency of anything from microseconds to millions of years. In the performing arts, rhythm is the timing of events on a human scale, of musical sounds and silences, of the steps of a trip the light fantastic, or the meter of speech communication and poesy. Rhythm may likewise refer to visual presentation, as "timed movement through space" (Jirousek 1995), and a common language of design unites rhythm with geometry.

In a visual composition , blueprint and rhythm are generally expressed by showing consistency with colors or lines . For instance, placing a red spiral at the lesser left and top correct, for example, volition cause the eye to move from one screw, to the other, and then to the infinite in between. The repetition of elements creates movement of the viewer 'south heart and tin can, therefore, make the artwork feel active. Hilma af Klint'southward Svanen (The Swan) exemplifies the visual representation of rhythm using color and symmetry.

Hilma af Klint, Svanen (The Swan), 1914: Color and symmetry work together in this painting to guide the eye of the viewer in a particular visual rhythm.

Proportion and Scale

Proportion is a measurement of the size and quantity of elements inside a composition.

Learning Objectives

Employ the concept of proportion to unlike works of art

Key Takeaways

Key Points

• Hierarchical proportion is a technique used in art, mostly in sculpture and painting, in which the creative person uses unnatural proportion or calibration to depict the relative importance of the figures in the artwork.
• Mathematically, proportion is the relation between elements and a whole. In compages, the whole is non just a edifice simply the set up and setting of the site.
• Among the various ancient artistic traditions, the harmonic proportions, human being proportions, cosmic orientations, various aspects of sacred geometry , and pocket-size whole-number ratios were all practical as function of the practice of architectural design.

Key Terms

• gold ratio:The irrational number (approximately 1·618), usually denoted by the Greek letter φ (phi), which is equal to the sum of its own reciprocal and 1, or, equivalently, is such that the ratio of 1 to the number is equal to the ratio of its reciprocal to 1. Some twentieth-century artists and architects take proportioned their works to approximate this—especially in the form of the golden rectangle, in which the ratio of the longer side to the shorter equals this number—believing this proportion to be aesthetically pleasing.

Proportion is a measurement of the size and quantity of elements within a composition . Hierarchical proportion is a technique used in art, mostly in sculpture and painting, in which the creative person uses unnatural proportion or scale to depict the relative importance of the figures in the artwork. In ancient Egyptian art, for example, gods and important political figures appear much larger than common people. Beginning with the Renaissance , artists recognized the connection between proportion and perspective , and the illusion of three-dimensional space . Images of the human being body in exaggerated proportion were used to depict the reality an artist interpreted.

Depiction of Narmer from the Narmer Palette: Narmer, a Predynastic ruler, accompanied past men conveying the standards of various local gods. This piece demonstrates the ancient Egyptians' use of proportion, with Narmer appearing larger than the other figures depicted.

Mathematically, proportion is the relation betwixt elements and a whole. In architecture, the whole is not just a building but the prepare and setting of the site. The things that make a building and its site "well shaped" include everything from the orientation of the site and the buildings on information technology, to the features of the grounds on which it is situated. Light, shade, current of air, pinnacle , and option of materials all relate to a standard of architectural proportion.

Compages has often used proportional systems to generate or constrain the forms considered suitable for inclusion in a building. In almost every building tradition, there is a system of mathematical relations which governs the relationships between aspects of the design. These systems of proportion are often quite simple: whole number ratios or incommensurable ratios (such as the gilded ratio) were determined using geometrical methods. Generally, the goal of a proportional system is to produce a sense of coherence and harmony amidst the elements of a edifice.

Among the various ancient artistic traditions, the harmonic proportions, human being proportions, catholic orientations, various aspects of sacred geometry, and small whole-number ratios were all applied equally function of the do of architectural design. For instance, the Greek classical architectural orders are all proportioned rather than dimensioned or measured modules, because the earliest modules were not based on body parts and their spans (fingers, palms, hands, and feet), but rather on column diameters and the widths of arcades and fenestrations .

Temple of Portanus: The Greek Temple of Portanus is an example of classical Greek architecture with its tetrastyle portico of four Ionic columns.

Typically, one set of column diameter modules used for casework and architectural moldings by the Egyptians and Romans is based on the proportions of the palm and the finger, while another less delicate module—used for door and window trim, tile work, and roofing in Mesopotamia and Greece—was based on the proportions of the hand and the thumb.

Dating back to the Pythagoreans, there was an thought that proportions should be related to standards, and that the more general and formulaic the standards, the amend. This concept—that there should exist beauty and elegance evidenced by a skillful limerick of well understood elements—underlies mathematics, art, and compages. The classical standards are a series of paired opposites designed to expand the dimensional constraints of harmony and proportion.

The organisation of space in art is referred to as limerick, and is an essential component of any work of art. Space can exist mostly defined equally the area that exists between any two identifiable points.

Space is conceived of differently in each medium . The infinite in a painting, for example, includes the background, foreground and middle ground, while three-dimensional space, like sculpture or installation , volition involve the distance between, around, and inside points of the work. Space is further categorized every bit positive or negative. "Positive space" can be defined as the subject of an artwork, while "negative space" can be defined as the infinite around the bailiwick.

Over the ages, space has been conceived of in various means. Artists have devoted a great deal of fourth dimension to experimenting with perspectives and degrees of flatness of the pictorial plane .

The perspective system has been a highly employed convention in Western art. Visually, information technology is an illusionist phenomenon, well suited to realism and the delineation of reality equally it appears. After spending hundreds of years developing linear perspective, Western artistic conventions near the authentic depiction of infinite went through a radical shift at the beginning of the 20th century. The innovations of Cubism and subsequent modernist movements represented an of import shift in the use of space within Western art, the impact of which is still being felt.

Pablo Picasso, Les Demoiselles d'Avignon, 1907: Les Demoiselles d'Avignon is an example of cubist art, which has a trend to flatten the picture aeroplane, and its use of abstruse shapes and irregular forms propose multiple points of view within a single image.

Two dimensional, or bi-dimensional, space is a geometric model of the planar projection of the physical universe in which we live. The two dimensions are normally called length and width. Both directions lie on the same plane . In physics, our bi-dimensional space is viewed as a planar representation of the space in which nosotros motility.

In art composition , cartoon is a form of visual art that makes use of whatever number of cartoon instruments to mark a 2-dimensional medium (meaning that the object does not have depth). One of the simplest and most efficient ways of communicating visual ideas, the medium has been a popular and fundamental means of public expression throughout man history. Additionally, the relative availability of basic drawing instruments makes drawing more universal than most other media.

Measuring the dimensions of a discipline while blocking in the drawing is an important step in producing a realistic rendition of a bailiwick. Tools such as a compass can be used to measure out the angles of different sides. These angles can be reproduced on the cartoon surface then rechecked to brand sure they are accurate. Another form of measurement is to compare the relative sizes of different parts of the discipline with each other. A finger placed at a indicate along the drawing implement can be used to compare that dimension with other parts of the image. A ruler tin can be used both every bit a straightedge and a device to compute proportions. When attempting to draw a complicated shape such as a man effigy, it is helpful at kickoff to represent the grade with a set of archaic shapes.

Almost whatever dimensional course can be represented past some combination of the cube, sphere, cylinder, and cone. In one case these basic shapes have been assembled into a likeness, and then the drawing can be refined into a more accurate and polished grade. The lines of the primitive shapes are removed and replaced by the last likeness. A more than refined art of figure drawing relies upon the creative person possessing a deep agreement of anatomy and the human proportions. A trained artist is familiar with the skeleton structure, joint location, muscle placement, tendon move, and how the different parts work together during move. This allows the artist to return more natural poses that exercise non appear artificially stiff. The artist is also familiar with how the proportions vary depending on the historic period of the subject, particularly when drawing a portrait.

• Systematic attempts to evolve a organisation of perspective are usually considered to have begun around the 5th century B.C. in the art of Aboriginal Hellenic republic.
• The earliest art paintings and drawings typically sized objects and characters hierarchically according to their spiritual or thematic importance, non their altitude from the viewer .
• In Medieval Europe, the apply and sophistication of attempts to convey distance increased steadily but without a ground in a systematic theory.
• Past the Renaissance , well-nigh every artist in Italy used geometrical perspective in their paintings, both to portray depth and also as a new and "of the moment" compositional method.

Key Terms

• curvilinear:Having bends; curved; formed past curved lines.
• horizon line:A horizontal line in perspective cartoon, straight contrary the viewer's eye and frequently implied, that represents objects infinitely far away and determines the bending or perspective from which the viewer sees the work.
• vanishing signal:The point in a perspective cartoon at which parallel lines receding from an observer seem to converge.
• Perspective:The technique of representing three-dimensional objects on a 2-dimensional surface.

In art, perspective is an guess representation on a apartment surface of an image as it is seen past the eye, calculated past bold a item vanishing bespeak . Systematic attempts to evolve a arrangement of perspective are usually considered to accept begun effectually the fifth century BCE in the art of Aboriginal Greece. By the subsequently periods of antiquity , artists—especially those in less popular traditions—were well aware that afar objects could be shown smaller than those shut at manus for increased illusionism. Just whether this convention was actually used in a work depended on many factors. Some of the paintings constitute in the ruins of Pompeii evidence a remarkable realism and perspective for their fourth dimension.

The earliest fine art paintings and drawings typically sized objects and characters hierarchically according to their spiritual or thematic importance, not their distance from the viewer. The virtually important figures are often shown as the highest in a composition , also from hieratic motives, leading to the "vertical perspective" common in the art of Ancient Egypt , where a group of "nearer" figures are shown below the larger figure(southward).

The art of the Migration Flow had no tradition of attempting compositions of large numbers of figures, and Early Medieval art was irksome and inconsistent in relearning the convention from classical models, though the process tin can be seen underway in Carolingian fine art. European Medieval artists were enlightened of the general principle of varying the relative size of elements according to altitude, and use and sophistication of attempts to convey distance increased steadily during the period, merely without a footing in a systematic theory.

By the Renaissance, however, nearly every creative person in Italy used geometrical perspective in their paintings. Not only was this apply of perspective a mode to portray depth, just it was also a new method of composing a painting. Paintings began to show a single, unified scene, rather than a combination of several. For a while, perspective remained the domain of Florence. Gradually, and partly through the movement of academies of the arts, the Italian techniques became part of the training of artists across Europe and, later, other parts of the globe.

Perspective in Renaissance Painting: Pietro Perugino'south usage of perspective in this fresco at the Sistine Chapel (1481–82) helped bring the Renaissance to Rome.

A drawing has i-bespeak perspective when information technology contains merely ane vanishing point on the horizon line . This type of perspective is typically used for images of roads, railway tracks, hallways, or buildings viewed so that the front end is direct facing the viewer. Whatever objects that are made upward of lines either directly parallel with the viewer's line of sight or direct perpendicular (the railroad slats) can exist represented with 1-point perspective. These parallel lines converge at the vanishing point.

Two-betoken perspective tin can be used to depict the same objects every bit one-point perspective, but rotated—such as looking at the corner of a house, or looking at ii forked roads compress into the distance. In looking at a firm from the corner, for example, one wall would recede towards one vanishing point and the other wall would recede towards the reverse vanishing indicate.

Three-point perspective is used for buildings depicted from to a higher place or below. In addition to the 2 vanishing points from before, one for each wall, there is at present a third one for how those walls recede into the basis . This third vanishing betoken would exist below the footing.

Four-bespeak perspective is the curvilinear variant of two-bespeak perspective. The resulting elongated frame can exist used both horizontally and vertically. Like all other foreshortened variants of perspective, four-indicate perspective starts off with a horizon line, followed by four equally spaced vanishing points to delineate four vertical lines. Because vanishing points exist only when parallel lines are present in the scene, a perspective with no vanishing points ("aught-betoken") occurs if the viewer is observing a non-rectilinear scene. The near mutual instance of a nonlinear scene is a natural scene (e.k., a mountain range), which oft does not contain any parallel lines. A perspective without vanishing points tin can still create a sense of depth.

Distortions of Space and Foreshortening

Distortion is used to create various representations of space in two-dimensional works of art.

Key Points

• Perspective projection distortion is the inevitable misrepresentation of three-dimensional space when drawn or "projected" onto a ii-dimensional surface. It is incommunicable to accurately depict three-dimensional reality on a two-dimensional plane .
• Nonetheless, there are several constructs available which permit for seemingly accurate representation. Perspective projection can be used to mirror how the eye sees by the use of one or more vanishing points .
• Although distortion can be irregular or follow many patterns, the most unremarkably encountered distortions in composition , especially in photography, are radially symmetric, or approximately so, arising from the symmetry of a photographic lens.

Key Terms

• radial:Arranged similar rays that radiate from, or converge into, a common center
• project:The prototype that a translucent object casts onto another object.
• foreshortening:A technique for creating the appearance that the object of a drawing is extending into space by shortening the lines with which that object is fatigued.

A distortion is the alteration of the original shape (or other characteristic) of an object, image, sound, or other form of information or representation. Distortion can be wanted or unwanted by the creative person. Baloney is usually unwanted when it concerns physical degradation of a work. Nevertheless, it is more commonly referred to in terms of perspective, where it is employed to create realistic representations of space in two-dimensional works of fine art.

Perspective Project Distortion

Perspective projection baloney is the inevitable misrepresentation of three-dimensional space when fatigued or "projected" onto a 2-dimensional surface. It is impossible to accurately depict three-dimensional reality on a two-dimensional aeroplane. However, at that place are several constructs bachelor that allow for seemingly accurate representation. The most common of these is perspective projection. Perspective projection tin can exist used to mirror how the eye sees by making use of one or more vanishing points.

Giotto, Lamentation (The Mourning of Christ), 1305–1306: Giotto is 1 of the most notable pre-Renaissance artists to recognize baloney on two-dimensional planes.

Foreshortening

Foreshortening is the visual effect or optical illusion that causes an object or altitude to appear shorter than information technology actually is because it is angled toward the viewer . Although foreshortening is an important element in art where visual perspective is beingness depicted, foreshortening occurs in other types of two-dimensional representations of 3-dimensional scenes, such as oblique parallel projection drawings.

The physiological ground of visual foreshortening was undefined until the twelvemonth k when the Arabian mathematician and philosopher, Alhazen, in his Perspectiva, first explained that lite projects conically into the eye. A method for presenting foreshortened geometry systematically onto a plane surface was unknown for another 300 years. The artist Giotto may have been the offset to recognize that the image beheld by the eye is distorted: to the center, parallel lines appear to intersect (like the afar edges of a path or road), whereas in "undistorted" nature, they do non. In many of Giotto's paintings, perspective is employed to accomplish diverse distortion effects.

Foreshortening: This painting illustrates Melozzo da Forlì'southward usage of upward foreshortening in his frescoes at The Basilica della Santa Casa.

Distortion in Photography

In photography, the projection machinery is light reflected from an object. To execute a cartoon using perspective projection, projectors emanate from all points of an object and intersect at a station signal. These projectors intersect with an imaginary airplane of projection and an prototype is created on the aeroplane past the points of intersection. The resulting image on the project airplane reproduces the image of the object as it is beheld from the station betoken.

Radial distortion can usually exist classified as one of two primary types: barrel baloney and pincushion distortion. Barrel distortion occurs when prototype magnification decreases with distance from the optical centrality. The credible effect is that of an image which has been mapped around a sphere (or butt). Fisheye lenses, which accept hemispherical views, utilize this blazon of baloney as a way to map an infinitely broad object plane into a finite image expanse.

On the other hand, in pincushion distortion, the prototype magnification increases with the distance from the optical axis. The visible consequence is that lines that do non go through the eye of the epitome are bowed inwards, towards the center of the image, like a pincushion. A sure corporeality of pincushion baloney is often establish with visual optical instruments (i.e., binoculars), where information technology serves to eliminate the globe event.

Cylindrical perspective is a course of distortion acquired past fisheye and panoramic lenses, which reproduce straight horizontal lines above and below the lens axis level equally curved, while reproducing directly horizontal lines on lens centrality level as directly. This is also a common feature of wide-angle anamorphic lenses of less than 40mm focal length in cinematography. Essentially information technology is just butt distortion, but only in the horizontal plane. It is an artifact of the squeezing process that anamorphic lenses practise to fit widescreen images onto standard-width pic.
