(photography) an
instrument for measuring a
negative's density (
relative degree of opaqueness).
a
meter used by professionals for measuring optical density (how opaque something is), of a photographic
negative, print, or slide. The
information obtained from the densitometer is used to adjust various pieces of
equipment used in
producing copies so that each
copy produced will
look exactly like or
better than the original photograph. It's
got to be on every
negative, and it's
got to be at least a
quarter-of-an-inch
square, and it's
got to match exactly on a densitometer.

instrument used in photography and printing to
measure the density of an exposed and
processed photograph or the density of ink on a
final printed
sheet. Density is the
relative darkness of film or ink. In photography, the density of film is affected by such
factors as the amount of
exposure to light (the longer the film is exposed, the denser it becomes), as well as how the film is
developed. In printing, density is affected by such
factors as ink
quantity on the printed
page. A densitometer allows a photographer to
measure the density of a photograph and thus regulate its
exposure and development, and enables a printer to ensure that the proper amount of ink is being used throughout a printing
job.
