The word vignette, from the same root as vine, originally referred to a decorative border in a book. Later, the word came to be used for a photographic portrait which is clear in t......

(Digital cameras and photo printers) Fading off the sides of a picture into plain white or black instead of having abrupt edges. Also unintentional loss of brightness at the edge of the image. Wide angle lenses are particularly susceptible. However, the problem can be more or less avoided by removing the elements causing the effect, such as a filt...
