Usually I take a lot of pictures, but I don't like to retouch them. Editing just one photograph could take hours of work, and I think it is better spending a few minutes or seconds setting up the camera. Besides, some picture errors are impossible to correct in Photoshop.
Nevertheless, there is some kind of photography that requires a digital laboratory. One of them is the classic black & white.
About the picture on the left: It was taken (by me) in The Netherlands in 2008, and now is processed in B&W.
