Panchromatic film

Description

Black and white film that is spectrally sensitive to the complete visible spectral range versus normal silver halide film, which is most sensitive to the blue region. The first panchromatic plate, Azaline, was developed in 1884 in Germany by H. W. Vogel when he used dyes to increase the sensitivity of green and blue wavelengths (Nadeau 1997). Early panchromatic emulsions were used primarily for three color reproduction. Kodak experimented with their use for motion pictures in 1913 and by 1926 they were widely used for motion pictures.
