lthough most people that view an image made by a fisheye lens think it is distorted, humans actually sense their environment with curvilinear perspective. This sensation is based on the physiology of the eye, with a primary contributor being the fact that we project light and focus it on the interior of a hemispheric surface. The field of view from the two eyes combined creates an oval asymmetric image with ~190 degrees horizontal by ~115 degrees vertical coverage, subject to individual variability.
Resolution and color sensation are not uniform across this field, with excellent quality possible only in a tiny, slightly off-center area known as the fovea. Most of the time, we are aware and thus perceive based on the sensations received in the fovea, while generally ignoring the rest. The fovea, being an extremely small sensor, performs like an acute telephoto lens resulting in rectilinear perception. Over such a narrow angle field of view, all perspective schemes appear nearly identical.
With a little effort and practice, it is possible to shift attention to the entire retina, thereby widening the angle of view and perceiving full sensor data. This will reveal the curvature of natural fisheye perspective and help to broaden understanding of reality.
- Sensation: detecting physical energy….
- Perception: selecting, organizing, and interpreting sensory information….
