Stefan is a German painter/photographer living on Ibiza in Spain. His portfolio contains some very nice portraits. An interview with him is published on Through the Looking Glass.
Stefan on taking portraits (from the interview):
"Both the photographer and the one being photographed must feel good, feel free. It can also happen that at the first encounter no picture is made, that there have to be several meetings to establish the trust I am speaking of. Other times it happens quickly. Every person is different, has her or his own times, reacts differently to the camera. To me, as a photographer, the most important things are the emotions of the model; they have to be positive and open. If somebody doesn’t want to be photographed I respect that wish and don’t take pictures. No problem at all. So painting is a mere expression of myself and my feelings, photography on the other side is an interaction with the other human being in front of the lens."
