Perspective distortion takes two forms: extension distortion and compression distortion, also called wide-angle distortion and long-lens or telephoto distortion, [1] when talking about images with the same field size. Extension or wide-angle distortion can be seen in images shot from close using a wide-angle lens (with an angle of view wider ...
The anamorphic distortion of the source image crucial to the illusion can be understood by likening the images to projections of a 3D object onto a plane (e.g. a sheet of paper) originating from the location of the viewer's eyes. The base of the object meets the plane where the object stands, while the tip of the object is "projected" to a more ...
A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic or hemispherical image. [4] [5]: 145 Fisheye lenses achieve extremely wide angles of view, well beyond any rectilinear lens.
A figure explaining point-projection prospective. S is the distance between an observer's eye and an observation point on an object that is a long rectangular wall facing to the observer at a tilted angle. If the observation distance becomes N times longer, then the apparent height of the wall at the observation point is roughly N times smaller.
A cameraman using an anamorphic attachment uses a spherical lens of a different focal length than they would use for Academy format (i.e. one sufficient to produce an image the full height of the frame and twice its width), and the anamorphic attachment squeezes the image (in the horizontal plane only) to half-width.

It has been argued that the Ebbinghaus illusion distorts perception of size, but not action. A study by neuroscientist Melvyn A. Goodale showed that when a subject is required to respond to a physical model of the illusion by grasping the central circle, the scaling of the grip aperture was unaffected by the perceived size distortion.

Micropsia is a condition affecting human visual perception in which objects are perceived to be smaller than they actually are. Micropsia can be caused by optical factors (such as wearing glasses), by distortion of images in the eye (such as optically, via swelling of the cornea or from changes in the shape of the retina such as from retinal edema, macular degeneration, or central serous ...
