Bolex 18-3 DUO

Bolex 18–3 DUO projection and recording camera, made for Super 8 and Standard 8 mm film. The camera projects 3 frames per second without flashing the light, but the shutter would spin as if it were 24 frames, while the transport mechanism advanced the film at only about three frames per second. The camera is self-winding, which meant it did not need to be wound by hand, a common feature in later models. It was considered a very compact and technical camera. Bolex projectors were on the more expensive side and were of very high quality. The difference between Standard 8 and Super 8 is that the perforations on Super 8 are smaller, which allows for a larger image frame. Super 8 films were usually in cartridges, so they didn't need to be spliced in a darkroom. You had to be careful not to play a Super 8 film on a standard setting, as the film would be destroyed.
