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. Spectral Sensitivity: Shows the equivalent energy needed at each wavelength in order to activate the emulsion so that it produces a neutral density of . 75. [. . . ]
