the distance between the nearest and the furthest objects that give an image judged to be in focus in a camera.
a room from which normal light is excluded, used for developing photographs.

a light source suitable for use in a photographic darkroom
a light-sensitive coating for photographic films and plates, containing crystals of a silver compound dispersed in a medium such as gelatin.
The silver crystals that make up an image on a negative or print
the measure of a photographic film's sensitivity to light, determined by sensitometry and measured on various numerical scales
