just read this and it works great. if you use USM then you know that it's a powerful sharpening tool but this setting does not sharpen the image but does enhance contrast. open USM and choose a setting of
amount; 40-50- your guess
radias; around 160- your guess
threshold; 0- your guess
click the prview button on and off to see your results.

enjoy,
roy

I use a freeware program The Gimp and use the USM facility.

The only difference is that the numbers recommended for Photo shop do not apply.

With experimentation I have developed what I hope are good valuies for threshold, radius and amount.

But it does vary from image to image, depending on the contrast level as USM does bring up the overall contrast.

The general rule is that the last thing you do is apply USM as it will also vary depending on the size of the image.

When I reduce the size of an image for web posting they seem to need more USM.

i'll ck the gimp, i have it loaded. the settings i posted are just a place to start but should be pretty much universal with any program. yes, sharpening should be use last after all other PP has been done. just as noise removal should be the first thing you do.

Those settings really seem to saturate the photo.

phil, i've got gimpshop. you are right, the numbers are all different. it's awful slow also.. they are also too strong in PSP9. PSE4 is fine.

guess i'll have to say use these numbers in adobe programs..
