What does the acronym GRAM stand for in relation to visual perception?

The acronym GRAM stands for various principles used to interpret visual perception, particularly in the context of depth and spatial awareness. In this specific context, aerial perspective refers to the way the atmosphere affects the appearance of objects at a distance. As objects become further away, they tend to appear lighter, less saturated, and often blurrier due to the scattering of light by atmospheric particles. This principle plays a significant role in how we perceive depth and distance within a visual scene.

Aerial perspective is a critical concept in art and visual sciences, as it helps in creating a sense of depth and realism in two-dimensional representations. By understanding and applying this principle, artists and designers can effectively guide the viewer's perception of space.
