Definitions for "Exposure latitude"
The range, in f-stop, that deviates from the optical exposure but will still produce acceptable results on a specific film.
The range of exposure at which the photosensitive material (film or sensor) will produce an acceptable image. Most slide films have small exposure latitude (in the 1-stop range). Most print films have big exposure latitude (in the 5-stop range), because exposure can be compensated in the printing stage. Comments & Discussion
