Color reproduction in color film | |||||
Color film (reversal color film) has a layer of photosensitive chemicals that react to the RGB wavelengths of light. When developed, these chmicals are replaced to form a CMY pigment image. | |||||
When negative film is used, it is impossible to view the natural image without first making a color print. The permissible latitude for exposure is greater than for positive film because the negative color can be corrected during the printing process. | |||||
In general, exposure of negative color film can be greater than that of reversal color film; exposure of the reversal color film has to be conservative. | |||||
Digital cameras do not use film. They store data in RGB mode, which can be used directly by a computer. They are extremely convenient because the steps of developing, printing, and scanning are eliminated. However, the image quality is still inferior to that of silver nitrate film. | |||||
