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.

36 exposures - 200 ISO or 36 exposures - 400 ISO
Lazer film adds green and blue lines to your photographs. The effect includes the sprocket holes, so it‘s great to try lazer film with cameras that also expose the sprocket holes. Try shooting a full roll in landscape format: when you get the pictures printed the lines will connect successive frames throughout the entire roll making a great panorama to decorate your walls with!
Careful with strong underexposure as the effect might dominate your image.
