I'm interested in achieving the effect Simon Chaput gets on his fantastic nudes. They look like sand dunes or some other kind of black and white landscape. Basically a fully black frame with a bright silhouette cutting through the darkness. You can see what I'm talking about by going to www.simonchaput.com Go to Black and White, and then Nudes. I'm particularly interested in the photographs that are nothing more than a thin white outline. How can I achieve this result? Will it work with just one or two light sources? I have a wireless speedlight setup (580EX and 430EX) - where should I place them to get this? Any direction is very much appreciated. Thanks!
