I have always wondered why we see pictures the way that we do and why is the life behind a lens so fascinating? As defined by Casper J. Erkrelens, "A picture is a powerful medium for inducing the illusion that one perceives a three-dimensional space." It is first important to discuss how we see an image. Reflection of light is the short answer. The reflection of light enters the eye through the pupil, which is the focused by the cornea and the lens. This then hits the retina where the visual receptors, rods and cones, are. This then travels to the brain for processing. What is so interesting about a photograph is that how familiar we are with a setting determines our perception of an image. Shape and relative size are cues for distance from the photographer to the object.
The psychology of Perception involves the interaction of our senses and our conscious mind. Perception is involved in every aspect of our lives as we make decisions and judgments based on what we experience. If you study diligently you will leave this course with a broad understanding of sensation and perception. From this general understanding you will be able to further investigate areas of interest by means of literature review and research on specific topics.
