Panchromatic plates cost two to three times as much, and had to be developed in total darkness, unlike orthochromatic—which, being insensitive to red, could be developed under a red light in the darkroom. [3] And the process that increased the film's sensitivity to yellow and red also made it oversensitive to blue and violet, requiring a ...
In analog photography, it is a chemical process carried out on metal salt-based prints, such as silver prints, iron-based prints (cyanotype or Van Dyke brown), or platinum or palladium prints. This darkroom process cannot be performed with a color photograph. The effects of this process can be emulated with software in digital photography.
