Color film that gives a positive image directly on the film after processing, instead of a negative. It is also called slide film or transparency film. The colors and tones look like the original scene when you hold the film up to the light. Traditionally, each frame was cut and put in a small cardboard or plastic mount for viewing with a projector. Kodachrome and Ektachrome are well-known examples. Reversal film has less exposure latitude than color negative film, so exposure must be accurate.
