In our last interview with him he highlighted: „I have color photographs, quite a few, but what I really felt was my own was the world of black and white images. It's an abstraction: the harmony of dark and light shades creates the image. At first, we worked with harsh tones, almost graphic effects. On my long trips I always had two cameras with me, one with color film. In those cases, you have to make a decision - what was a really important subject was always shot on black and white film."
