The movie was shot with a crew not bigger than five people in order to achieve a space as free as possible to work for the actors. There was the cinematographer with his 1st ac, one guy for sound, an assistant to the director and the director himself.
The director and the cinematographer decided to work without any film lights throughout the project. In this form they could achieve as much shooting time with the actors as possible.
Schwarz Weiss Bunt was shot in 20 days of shooting with around 10 of them being not longer than 5 hours.
