In photography and optics, vignetting (/ v ɪ n ˈ j ɛ t ɪ ŋ / vin-YET-ing) is a reduction of an image's brightness or saturation toward the periphery compared to the image center. The word vignette, from the same root as vine, originally referred to a decorative border in a book.
Also may mean "Perspective Control" for a lens that has the ability to shift to tilt to control linear perspective in an image. May also stand for personal computer in conjunction with digital photography. PDAF: Phase-detection autofocus. One of the mechanisms of automatic lens focusing. PF: Purple fringing. A form of chromatic aberration in ...
An example of the use of f-numbers in photography is the sunny 16 rule: an approximately correct exposure will be obtained on a sunny day by using an aperture of f /16 and the shutter speed closest to the reciprocal of the ISO speed of the film; for example, using ISO 200 film, an aperture of f /16 and a shutter speed of 1 ⁄ 200 second. The f ...
In cases where the fill light is desired to be darker than what is available without artificial means, a flag or frame may be used to block ambient light and thereby provide what is called negative fill.

The Biogon and Hologon designs take advantage of the large negative elements to limit the light falloff of regular wide angle lenses. [1]: 150–152 [64] With a 110° field of view, the Hologon would otherwise have had a 3¼ stop corner light falloff, which is wider than the exposure latitude of contemporaneous films. Nonetheless, the Hologon ...

Soft light use is popular in photography and cinematography. By diffusing hard shadows, softening dark areas, and removing sharp edges, soft light produces more flattering images of the human form. [4] Colours may also appear richer and more realistic. [1]
