This MIGHT work: Sharpen a layer to the degree you want for you highlights. Sharpen a layer to the degree you want for you mids. Sharpen a layer to the degree you want for you shadows. Use the 'blending' in each layer to properly/decently combine the 3 layers. Definitely not as good, but it was sort of how I did it before CS2. Shawn
Also, Detail Enhancer in Optipix. Free trial version downloadable from www.reindeergraphics.com. But, if you already have CS, why not upgrade to CS2- it's worth it...
Before CS2 I used the following sharpening proceedure: 1. Convert the image type to 'Lab Color' in Image/Mode/Lab Color 2. In Channels select 'Lightness', i.e. the b/w part of the image. 3. In Filters/Sharpen/Unsharp select the amount of sharpening you think is OK (not too much). 4. Reselect the image mode you had been using (Note the colour will be reinstated). I don't know if this is how 'Smart Sharpen' works but this method certainly did a good job for me.
Smart sharpen is a deconvolver, and there's really no way to imitate it by merely adjusting local contrast.
