125 results about "Reversal film" patented technology

In photography, reversal film is a type of photographic film that produces a positive image on a transparent base. The film is processed to produce transparencies or diapositives (abbreviated as "diafilm" in many countries) instead of negatives and prints. Reversal film is produced in various sizes, from 35 mm roll film to 8×10 inch sheet film.
