Quick Summary

Panchromatic film is a type of photographic film that is sensitive to all colors within the visible spectrum. Introduced in 1904, these films were a significant advancement over earlier emulsions that were only sensitive to ultraviolet, violet, and blue light.12

Panchromatic films record the colors of a subject as varying shades of gray, with the brightness of the gray tone corresponding to the visual brightness of the original color. This ability to accurately capture the luminance of all colors makes them suitable for general photography. Orthopanchromatic film is a variation that has a color sensitivity that most closely matches that of the human eye.23

…with a thin film of panchromatic (i.e., sensitive to all colors) emulsion, and it resulted in a positive color transparency. Because Autochrome was a color transparency and could be viewed only by reflected light, however, researchers continued to look for improvements and alternative color processes.
