Polaroid's new ISO 40 color transparency film develops in a minute using the Polaroid 35-mm Autoprocess system. Unlike widely used subtractive color photography, Polachrome employs an additive color screen. The process offers interesting characteristics and advantages. Polapan black and white continuous-tone transparency film and Polagraph HC black and white high contrast transparency film, two other new Autoprocess films, are mentioned. -- AATA
