The brain responds effortlessly to four aspects of viewed images. These properties are color, form, depth, and movement. Using these visual cues a visual communicator can effectively design images that will have lasting impressions on their viewers.1

An image that exploits the visual que of depth is an optical illusion of a long pillared hallway. As humans we see in three dimensions. Because our eyes are set slightly apart, both eyes process a scene from two different perspectives. This disparity is responsible for the illusion of depth.1

The optic nerve in each eye intersects at the optic chiasma. These nerves are responsible for sending images through the brain which result in quick visual response times.1 Depth perception is needed not only for mobility, but allows humans to experience further dimension in their sight. This is particularly important for visual communicators to keep in mind when developing memorable images.
