These films are the result of a collaboration between KONO! and dubblefilm / dubble.
KONO! was started in 2014 by Uwe Mimoun and specializes in offering creative 35mm films. Most of the films are pre-exposed with the "Reanimator" and hand-packed.
Dubble was founded a year earlier and is a mobile app. The app enables a digital version of film swapping. To do this, you take a photo over which an image from another user is superimposed, thus obtaining a double exposure.
All of these films are effect films. That means the color films were pre-exposed to achieve a special result. All color negative films are developed using the C-41 process.
