Objects that are superimposed are perceived as having depth, even if they are all situated the same distance from the eye, as long as they overlap. F IGURE Interposition. 12). We always perceive distant objects as soft and slightly blurry as well as having a bluish hue. Atmospheric haze and fog are also examples of this kind of depth perception, even if these phenomena are closer to the observer than pure atmospheric scattering. F IGURE Aerial perspective. 12 R ELATIVE H EIGHT Relative height depth perception is related to aerial perspective.

This quick correction is called flick. Tremor, drift, and flick—the first three types of eye movement—ensure that an image is continuously refreshing the retina’s photoreceptors and avoiding image adaptation. Since the retina gets “tired” of an image if it is kept still, it must refresh in order to keep the visual acuity intact. This is why the eye has to keep moving when tracking an object. The eye actually does not move smoothly when tracking an object in its visual field. It performs a series of short, jerky movements that predict the speed and location of the object it tracks.

Long lasting) than regular film. No matter what kind of film is used, photography is still about the capture and control of light as it falls on a scene or subject. For most people, however, it is hard to see the varying levels of luminance on a scene due to humans’ perception of color. The best method of solving this problem is to perceive the scene in terms of black and white. For other people, it is even harder to visualize a color scene in black and white, so they use visualization aids with filtration.
