Panchromatic

Panchromatic means sensitive to all colours of light. Early ortochromatic film had very little sensitivity to red light, leaving red subjects as black in the resulting images. Panchromatic film - originally made by adding dyes to red-insensitive film, a result of work by Dr. Adolf Miethe, is capable of recording red subjects. Panchromatic films were, however, still too sensitive to blue light.

A variation of the panchromatic film was the so called superpanchromatic film (also called hochpanschromatisch, i.e. highpanchromatic in German), which had additionally increased sensitivity to red color - as it was intended for use in artificial (tungsten) light of low color temperature. Supermanchromatic film had generally high speed (e.g. 400 ASA).
