Experiments with a self-made slit-scan camera:
In front of the lens of a DSLR camera a cardboard with a vertical slit (0.5 mm wide) is mounted so that it can be moved during the exposure. Landscape pictures with moving and stable camera and portraits with dancing models (Sabine and John, Thanks!) have been taken during the Weinviertler Fotowochen in the Workshop with John Hilliard, 2015.
