Darkroom film fogging must be eliminated because it causes which change in film contrast?

Explanation:
Darkroom fogging adds unwanted density across the film, so the difference between adjacent gray levels is reduced. This extra density effectively flattens the film’s exposure–density response, especially in the mid-density range where many diagnostic details reside. The net result is a loss of contrast in those mid-tones, not an increase. Fogging does not selectively boost contrast at the toe or shoulder; it broadens and dulls the overall range of visible densities.
