Picture plane- is the flat surface on which a picture is created.
Perspective- refers to a wide of techniques that artists use to create an illusion of three- dimensional space beyond the picture, including diminishing scale perspective, stacked perspective, overlapping forms, atmospheric perspective, and chiaroscuro.
Diminishing scale perspective- an illusion of depth on a two- dimensional surface by making some objects smaller than others, The smaller objects will appear to be farther away.
Stacked perspective- an illusion of depth on a two- dimensional surface by placing some objects higher in the composition. The objects higher up in the composition will appear to be farther away.
Overlapping forms- an illusion of depth on a two- dimensional surface by placing two or more figures next to each other so that one figure is presented only in part and its missing part corresponds to the position of another figure. The whole figure will appear to be in standing in front of the partial figure.
Atmospheric perspective- derives from the way certain weather conditions can make distant objects seem fuzzy. Artists can create the illusion of depth on a two- dimensional picture plane through gradations of texture, tone, or color, Objects that the artist wants to appear close are made more detailed, darker, and warmer in color. Objects that the artist wants to appear to be farther away are made less detailed, lighter and cooler in color.
Chiaroscuro- to create an illusion of depth, artist use chiaroscuro for a dramatic contrast of light and shadow effect.
Negative space- The empty space left after the positive elements have been created by the artist.
