Photoshop CS2 has a new sharpen tool, called 'Smart Sharpen', but can it beat a multi-layer 'Unsharp Mask'? These look pretty close to me, but can you tell which is which: a: b: Here is another example in the same order: a: b: Smart sharpen is very easy to use. You set the sharpening similar to the way you do for USM. Then fade the shadows and highlights until the halos disappear. I did an amount of 396 and radius of 0.2, then faded the highlights 64% and shadows 10%. Supposedly, Smart Sharpen is supposed to sharpen detail but not noise. These shots are very high ISO, does that seem to be the case?
