One of the neat features about unsharp mask is that it can be used to increase saturation and dynamic range. I played with the sliders using maybe 150 amount, 80 radius, 0 threshhold to start with. Next I went to a levels adjustment and moved the left slider towards the right until I liked the way the image looked. I ended by going back to unsharp masking and did a regular sharpen with Smart Sharpen (gaussian blur setting) in CS2, but you can use unsharp masking moved the amount slider the way you like it with a radius of only .4 and threshold of zero. I tried that in CS2, but Smart Sharpen worked better. It is a new feature in CS2 that I just love.
