This pictures were taken on 35mm film with a classic Olympus Pen rangefinder.
The camera is amazing, totally mechanic but automatic, it measures the exposure with a selenium panel attached to the side of the lens. One of the best designed cameras ever, it is as simple to use as a pen.
The film is Lomo 35mm ASA 400 developed by The darkroom in California. The prints are totally awesome, much better than this scans, they have something organic on them.
