Relative Log Exposure
D-Max: The density value for the film's darkest black. In prints, the whiteness of the brightest highlight, relative to the unprocessed print. Slope: The positive ratio of the log E increments of the straight line region of the curve, as determined by the 1/4-3/4 increment method. [. . . ] Reciprocity failure occurs during very long or very short exposures, requiring the photographer to increase exposure.
