Kodachrome

Kodachrome is a brand of color transparency (slide) film sold by Kodak. It was first sold as 16mm movie film in 1935, and as 8mm movie film and 135 film in 1936. Kodachrome is the oldest successfully mass-marketed color still film using a subtractive method. Kodachrome has undergone four major developing process changes over the years - the current is the K-14 process. Kodachrome is widely regarded as one of the best films available for the archival and professional market because of its color accuracy and dark-storage longevity.
