peterke actually wrote a Smart Sharpening tutorial a while back, I'm still in the process of transcribing the thing to html. Hang on then... off to check out the link (*

Thanks for this information!! Being a "newbie" to digital manipulation, I am limited by my own learning curve. This helps straighten out that curve and "sharpen" it.

Yes I remember Peterke sharpening tut. I tried it out, it seemed a little strange, but it really did sharpen up images. :0)

Ah! That's where that went. [Star??? Please add it to the Resource links... Luminous Landscape is a wonderful site! Don't know myself how the Brits do it, not being able to pronounce the words right and all. What IS gobsmacked, BTW?] I made a photoshop "Action" using this technique, and it mostly worked great. But the amount of gaussian blurring, and the curves adjustment to the found edges, plus the amount of sharpening, were a lot of variables to juggle. Is there a way to publish good "Action" scripts? Maybe should ask this over in Photoshop Forum... Think I will!

Yep, this seems to be the process allright ! I use it quite often. I first read about it in a Photoshop book a very long time ago (about 6 years or so) and experimented with it until I got some decent results in print. In the mean time, I've refined this technique somewhat (a colleague -absolute expert PS user- has given me some pointers). If I have some time, I'll write it all down and make it available. By the way, If you understand the digital processes behind this technique, you can develop quite sophisticated (and spectacular) "remove grain / noise" actions. I'm in the process of writing down some of my techniques for a friend of mine. So, when I'm finished, I'll pass those on to the forum mods...

Sounds good Peterke, One of the great things about the forums is sharing ideas and techniques. :0)

What I'm finding interesting as I play with the new technique and apply it to different image types is using glowing edges (instead of find edges) on a b&w channel. With that, you don't need to invert the mask. I've found at least one image that it worked better on for the sharpening ... but don't know yet what it was about that image that made it work so well. -=>Donald
