Do you have a 120 film camera? Want to shoot images with the sprocket holes exposed? Want to shoot specialty films that are not available in 120 format? If so, or you just like to play with film, these adapters are for you.

These Creative Commons (CC by SA) 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 35mm 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.

Since the Shapeways materials price cut, these have become affordable and the quality is superior РI recommend them highly as they are stronger than you can print at home, but you can make your own too, below.  They are open source and the only requirement is that if you sell them, you should comply with CC license specifications (in this case, attribution to me as the designer).
