ABSTRACT
Experiments in which subjects were exposed to a homogeneous visual field for a prolonged length of time led to some interesting results. When the visual field is not completely homogeneous, perception of the observed scene might be inaccurate unless appropriate visual cues are present. In the world of heterogeneous fields, people select what attracts their attention as figure. In uniformly exposed areas of photographs, the microstructure clumping of the silver or dye particles that make up the image is called graininess when judged subjectively and granularity when measured objectively to assign it a value. The term working space refers to negative space that serves a particular function in an image. A subjective camera angle immerses us into the scene and subject, as if we are part of the experience. An objective camera angle encourages us to remain more distant and neutral, like an observer of the situation.
