About time for another PP tip...
I've been playing about with contrast adjustments in CS3. There are loads of ways of adjusting contrast but they all affect the saturation of the image. Well, here's a way to increase contrast without altering colour saturation by using luminosity masks...
In the layers palette, go the to RGB tab. Hold control (command on a mac) and click on the RGB layer. This selects the brightest luminosity ranges. Switch back to the layers tab and perform a highlight boosting curves adjustment. Set the layer opacity to ~20-30%
Now repeat the process for the shadows. The only difference is you need to invert your luminosity selection (control + shift + I) to select the shadows and generate a shadow darkening curve.
