The general assumption that "undoctored" photos cannot distort a scene is incorrect. Perspective distortion is particularly noticeable in portraits taken with wide-angle lenses at short camera-to-subject distances. They generally give an unpleasant impression, making the nose appear too large with respect to the rest of the face, and distorting ...
The most characteristic features of linear perspective are that objects appear smaller as their distance from the observer increases, and that they are subject to foreshortening, meaning that an object's dimensions parallel to the line of sight appear shorter than its dimensions perpendicular to the line of sight. All objects will recede to ...
Because of foreshortening, the difference in convergence needed to see repeated patterns on different planes causes the brain to attribute different sizes to patterns with identical 2D sizes. In the autostereogram of three rows of cubes, while all cubes have the same physical 2D dimensions, the ones on the top row appear bigger, because they ...
The foreshortening factor (1/2 in this example) is inversely proportional to the tangent of the angle (63.43° in this example) between the projection plane (colored brown) and the projection lines (dotted). Front view of the same. Oblique projection is a type of parallel projection: it projects an image by intersecting parallel rays (projectors)

Linear perspective of a cube (left) and reverse perspective (right). The viewing plane is shown in blue, with the projection point where the red lines meet.
Luca Signorelli (c. 1441/1445 – 16 October 1523) was an Italian Renaissance painter from Cortona, in Tuscany, who was noted in particular for his ability as a draftsman and his use of foreshortening. His massive frescos of the Last Judgment (1499–1503) in Orvieto Cathedral are considered his masterpiece.
