Which of the following definitions
best describes emulsion latitude?
1.
The ability of a film to
reproduce brightness
differences
2.
The amount of deviation from
the correct exposure that will
still produce acceptable
densities
3.
The evenness of the emulsion
thickness applied to the film
base
4.
The variation in film
processing time that still
permits the emulsion to respond
to the action of the fixing
bath
What is exposure latitude?
1.
