The essential challenge of all artists working in 2 dimensions is the usage of space. It can be a challenge quickly addressed by acknowledging the flatness of the surface as modern painters did or delve into a myriad of choices of how space can be crafted. Such choices presented in art history include (but not limited to) realism/ illusionism, Byzantine, Pre- Renaissance, Renaissance, Cubism. All unavoidably deal with the issue of space selection, meaning and represent the thinking of that era.
John Singer Sargent
To understand this issue we first must look at the subjective nature of engaging space visually as humans. At best we can see just under 180 degrees ( an admittedly incomplete perception of the space that surrounds us.) Below are two examples from John Montagues's Basic Drawing Perspective.
Again remember our brain is comprehending information, in multiple ways, from an image projected upside down within our eye. From this information the brain uses conditioned responses to particular appearances of shapes and colors to process quickly. In this manner vision and it's subject are perceived. The very nature of the term perception, is the ability of the mind to grasp what is seen. The challenge in space depiction is the utilization of depth perception as it relates to:
COLOR (temperature, intensity, value)
CLARITY (focus vs blur)
SCALE ( relative size of objects)
SEQUENCING ( overlapping and placement of objects)
SHAPE DEFORMATION (the regularized shape in perspective and how the mind grasps these shapes as the vacillate between flatness and form)
Space and it's depiction is a loaded choice as it highlights and consciously omits/ edits certain information as it's expression needs. We all generally grow up being amazed by the simulacra ofillusionistic space, yet have unintentionally disregarded the multiple possibilities that space offers. It is the artists decision to make use of what best suits their "message" and equally important, enhances their perception of space, a skill necessary in engaging with all forms of 2 dimensional work whether it is advertising, fine art, design, illustration, photography. Below are examples highlighting some artists approach to handling space within these terms.
Thomas Moran
George Inness
Richard Parkes Bonington
The previous examples showcase an extreme depiction of spatial recession in the landscape format, foreground, middle ground and background. Atmospheric perspective is employed as we see colors of a more neutral hue in the background as well as cooler color and less contrasting values. Scale changes are evident as well as overlapping objects.
Richard Deibenkorn
In this example of Deibenforn we can see a tension between the flatness of the space and three dimensionality. It is a heavy "shape" composition which leans toward flatness, yet he employed a knowledge of color and values in spacial recession. Notice the shadows on the pavement.
Lucian Freud
Joan Semmel
Philip Pearlstein
The above examples display an approach to the figure in space through more traditional techniques. We see clear usage of sequencing particularly in Pearlstein (notice the mannequin behind, the in front of the model.) In the Semmel example she plays with the mirror (and extends the space) using color and scale. Notice the taper of the legs and the overlap. In the Freud example, we see clear overlaping of the body, foreshortening, color and scale (thigh/ knee to head ratio.)
