Contrast

Contrast is the dissimilarity or difference between things, acording to wiki.

I'm adding this because I submitted it to a contest on my favorite photo forum, talkphotography.co.uk. It has contests every month and I sometimes have a punt, this months subject was contrast, quite a tough one really, a lot of black and white images as you might suspect, heres my take on it.
A simple flash setup with lighting coming from a single 580EXII to the left the black polo was changed in CS3, not as easily as I first suspected. First I applied a layer mask (cutting out the polo using the pen tool) and just added an inverted adjustment layer, the problem with it is it turns the black shadows white which isn't what I wanted. I went back to the layer mask and used a levels adjustment to just bring down the levels of white and grey to black.
