These open source (CC by SA 3.0) adapters are a matched pair – one centers 35mm film canisters in a 120 format spool and the other is a 120 takeup spool, sized to wind 35mm film. These adapters allow shooting 35mm film in any 120 medium format film camera with a flat back plane, such as Flyer 6×6, and enable use of films that are not available in 120 format. The entire film is exposed, resulting in images out to the edges, sprocket holes and all, creating a unique effect.
On a curved film plane camera such as Clipper 6X18, the film will take a shortcut across, resulting in unexpected effects.
