pancol

Pancol, short for panchromatic, refers to a type of film or sensor that is sensitive to all visible wavelengths of light, from approximately 400 to 700 nanometers. This characteristic allows pancol film or sensors to capture a broad spectrum of colors, making them versatile for various photographic applications. Pancol film was particularly popular in the mid-20th century for its ability to produce high-quality black-and-white images with a wide range of tones and details. It was widely used in professional photography, including portraiture, journalism, and scientific documentation. The term "pancol" is also sometimes used to describe color films or sensors that are designed to capture a wide range of colors, although these are not strictly panchromatic in the traditional sense, as they also respond to infrared and ultraviolet light. Today, pancol film is largely obsolete, having been replaced by digital photography and advanced color film technologies. However, its historical significance and technical characteristics continue to be studied and appreciated by photographers and historians.
