35mm film stock

35mm film stock is a size of photography film. Before the popularity of digital cameras, it was the film stock most often used in single shot consumer cameras. Long reels of 35mm film were among the formats used for filming motion pictures. 16mm was also used, but for lower budget films. There was also an 8mm size used by ordinary consumers. Some of the highest-cost feature films were shot on 70mm, but relatively few cinemas had projectors that could could cope with them. Some smaller cinemas would project older films that had been transferred from 35mm to 16mm.
