Anotations

Scope note:

A subtractive color reversal process using a film with an integral tripack of black-and-white emulsions, each layer sensitized to a separate primary color. The film contains no dyes; the color developing agents and color couplers are supplied in development, each layer being dyed and bleached separately by carefully controlled processing through three machines, with separate drying between each machine. For Capstaff's two-color Kodachrome process, use "two-color processes."
