is the normalized value of the minimum (for example, the voltage or grey value of the black area) When the system can no longer resolve the bars, the black and white areas have the same value, so Contrast = 0. At very low spatial frequencies, C max = 1 and C min = 0 so Modulation = 1. Some modulation may be seen above the limiting resolution ...
Photographic film is a strip or sheet of transparent film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast, and resolution of the film. [ 1 ]
