Definition
"The essential tool of the photographic process is not the camera but the light-sensitive layer." László Moholy-Nagy
"With the advent of photography in 1839, painting underwent a radical transformation. Nowadays, the digital process is revolutionizing photography. The chemigram, fusion of painting and photography, is most likely the ultimate adventure of gelatin silver bromide." Pierre Cordier
