With more than 20 years of professional aerial photography culminating in the series "Colours of Water" in 2009, I felt the need to broaden my horizons and to take up photography on ground level as well. Aerial photography, a highly technical discipline, offers the opportunities of a unique perspective together with typical limitations, and heavily relies on formal esthetics and a keen eye for shapes and composition. The aerial perspective mainly shows the look of things, their outside appearance, while on ground level I try to convey inner worlds, the feel of people and situations.
