Revolog / Dubblefilm films are experimental, fun films which are handmade using 35mm colour / b&w negative films ranging from 200-400 ISO. The process varies with each different type, and the effects varies randomly.
35mm colour-negative film
36 exposures - 200 ISO
The effect of the 460nm film changes the colour of your picture monochromatically. Depending on exposure and the development and scanner settings of the photographic lab the pictures either appear blue/violet or yellow/green. Underexposure intensifies the colour, whereas overexposure dampens the effect of the film.
Since the effect covers the whole picture, but will not obstruct any parts of the motive, the film is really universally usable.
