Overview

At its core, space is the area in, around, and between objects. Space can also be thought of as a different type of perspective. Space also gives an illusion of a three-dimensional space that makes a painting look more realistic in a two-dimensional work of art.

Space

Space is the empty area surrounding real or implied objects. The pictorial space is flat. If looking at a digital work, the digital realm resides in cyberspace. Art responds to all of these kinds of space. There are many ways for the artist to present ideas of space.

Techniques for creating a sense of depth and the illusion of space include:

Size, overlapping, and position
Alternating value and texture
Changing brightness and color

1. Size, Overlapping, and Position

The size of one shape compared to another, often suggests that the larger the object is closer to us. In a similar understanding, if one shape overlaps another, the shape in front seems to be closer. Also, a shape lower in the picture plane also appears to be closer.
In Steve DiBenedetto's drawing, we recognize that the objects close to us appear larger than objects farther away, so the juxtaposition of large and smaller helicopter suggest deep space between two helicopters.
Overlapping images also creates the illusion that one object is in front of the other in space. The helicopters appear to be closer to us than the elaborately decorated red launching or landing pad below.
And because we are looking down on the screen, a sense of deep space is further suggested.2

In Michelangelo's Head of a Satyr hatching lines creates alternating value and texture. Hatching consists of a series of lines, close to and parallel to each other. Cross-hatching is a variant of hatching in which the lines overlap. Both are used to express value and create a greater sense of form and depth
The artwork created by Michelangelo is a cross-hatched pen-and-ink drawing. It gives the face solidity and depth. By building up layers of brown ink, Michelangelo overcomes the restrictions created by the thin line of the pen. 3

3. Changing brightness and color

In a painting, brighter colors may appear closer in a painting as dark or duller versions of the same color tend to recede. For example, an intense green will appear closer to the viewer than a darker green. We perceive color that is more intense as being closer.
In The Wreck of the Ole ’97, Thomas Hart Benton used brightness and color to create a sense of distance 3

Definition: Chiaroscuro

Chiaroscuro can produce dramatic effects
Chiaroscuro is an Italian term that translates as light-dark and refers to the balance and pattern of light and shade in a painting or drawing
Chiaroscuro is generally only remarked upon when it is a particularly prominent feature of the work, usually when the artist is using extreme contrasts of light and shade.
This method of applying value to a two-dimensional artwork creates the illusion of three dimensions
Renaissance artists identified five distinct areas of light and shadow: Highlight, light, core shadow, reflected light, and cast shadow. 3

Perspective

Perspective refers to different techniques artists use to suggest a three-dimensional (3D) space on a two-dimensional (2D) plane. Two types of perspective most commonly seen in the Western tradition will be discussed.

Linear Perspective

Linear perspective is seen when parallel lines meet at a point on the horizon of a 2D composition to convey a sense of depth that mimics 3D recession or depth.

Definition: Term

Depth: how far into, from front-to-back (also considered recession), or from side-to-side we can physically go into an object or appear to go into a composition.

Linear perspective uses horizontal lines and one or more vanishing points to create this illusion of three-dimensional space.

One point perspective: HL = horizon line. VP = vanishing point

One-point perspective

The following is an artwork that uses a one-point perspective. Sometimes, an artist will create more than one vanishing point to have the viewer focus on important forms in the composition. In this instance, that important form is Jesus Christ. Da Vinci composes the work by locating the vanishing point directly behind the head of Christ, thus drawing the viewer's attention to the center. His arms mirror the receding lines on the walls and ceiling, and, if we follow them as lines, would converge at the same vanishing point.

Leonardo da Vinci, The Last Supper, c. 1495-1498. Tempera. 181 in. x 346 in. Santa Maria della Grazie. Milan, Italy. "LEONARDO da Vinci The Last Supper 1498 Convent of Santa Maria delle Grazie, Milan" by normanrusin is marked with Public Domain Mark 1.0.

From the definition: “Parallel lines...” In this instance, there are implied lines (along the tops of the Apostles’ heads) creating the parallel line.

“Parallel lines that meet at a point on the horizon (this point is known as the vanishing point)...”

There are more implied lines (at the top of the doorways) creating a parallel line.

“Parallel lines that meet at a point on the horizon (of a 2D plane)...”

Next, there are literal lines (on the ceiling) that create a parallel line.

Now, there are more literal lines (on the ceiling) creating parallel lines.

Eventually, all the literal and implied lines meet at the vanishing point.

The definition continues with “...to create a sense of depth that mimics 3D recession”

Now, the definition is complete, "parallel lines that meet at a point on the horizon of a 2D plane to convey a sense of depth that mimics 3D recession or depth." Notice that the area outside of the window behind Jesus’ head looks like it's further away from us; specifically, that it is in the background.

Notice something else? On what form are all the lines directed to on the horizon? Jesus. In this composition, da Vinci is suggesting that Jesus is the most important figure
at his image of the last supper. In the Western tradition, the most important form in the artwork is always located at the vanishing point--a term that is sometimes called the focal point.

Two-point perspective

Two-point perspective occurs when the vertical edge of a cube is facing the viewer, exposing two sides that recede into the distance, one to each vanishing point.

Two-point Perspective

Caillebotte's (1848-1894) Paris Street; Rainy Day is an example of a work that uses two-point perspective. This type of perspective can be seen in the building in the background on the left-hand side of the composition.

Atmospheric Perspective

Atmospheric perspective is an artistic technique on a 2D plane that mimics what the eye sees when looking at forms in the distance.

All of the following criteria must be present for atmospheric perspective to be seen.

Forms at a distance must appear...

lighter in color

Notice the difference in the value between the forms in the foreground and those in the background.

less detailed

Although there are generally plants and streams of water in the mountains, such a level of detail cannot be seen in the background of this painting.

smaller in size

In real life, mountains are larger in size than men, but in this composition, the men are just as large (if not larger) than the mountains in the background.

Summary

Space is the empty area that surrounds real or implied objects.
Different types of perspective can be used to create a convincing sense of three-dimensionality on a two-dimensional plane.
The most common types of perspective used in Western tradition art are linear perspective and atmospheric perspective.

What element of art that is used to create an illusion of depth it can be two

Space is used to create the illusion of depth within an artwork. It can also refer to the positive and negative space between, around, or within objects. Forms are three-dimensional (length, width, height) and can be viewed from many angles.

Which technique can be used to show the illusion of depth?

Linear Perspective It is the use of lines and edges of objects to depict perspective distortion and thus the illusion of depth.

What is the visual illusion of depth in a two

Diagonal lines as diminishing scale An exemplification of diminishing scale, diagonal lines moving towards each other as they move up or down a painting or sketch give the illusion of depth. A real world example of this is a straight road that becomes skinnier as it approaches the distant horizon.
