I'm probably risking a lot of "DNMC" but hey, it's my comfort after a long day's work. Only one glass of course.
Lee Forst has a description of how to do this kind of picture in his book "Photos that sell". I thought I'd have a go myself.
Setup :
-20"cinema display with white screen as background
-black cardboard leaving only two vertical strips of light left and right
-black foamcore under the glass
-2 stops underexposed
