|The tonal range, including brightest highlights and deepest shadow detail,
that a film can record in a single image before the highlights wash out
or the shadows become muddy is called that film or Digital sensors exposure
The other way of defining exposure latitude is to say how much the film or digital sensor can be under-exposed or over-exposed and still produce usable images.
Latitude is defined in f-stops. Generally most negative films have an
exposure latitude of five to seven stops. Color transparency (slide) films
have much less exposure latitude -three to five f-stops. Present day digital
sensors are even more picky in exposure latitude than most color transparencies.
