Kodachrome

Kodachrome is a brand of color transparency (slide) film sold by Kodak. First sold in 1935, it is one of the oldest (if not the oldest) mass-marketed color still film. Kodachrome has been through many incarnations and processing processes over the years; the current (2003) is the K14-process Kodachrome.

Kodachrome film has mostly been replaced by E6-process transparency films, though it still finds use for applications where its archival stability is valued.

Kodachrome film has a different structure to its emulsion than other slide films. This makes its rendering of color and response to light unique. A Kodachrome slide is quickly detectable by an expert reviewing a series of slides with indeterminant origins.
