Since I discovered it, I use it on almost every picture. I entered it as an automatic action in photoshop and just run it when time comes.

You'll find it here: http://www.trekearth.com/techniques/unsharp-mask.htm

I saw it in this ws of a picture of mine http://www.trekearth.com/workshops/790571/photo121051.htm and I didn't understand it either. I just recorded it as a photoshop action. Thanks.

i'm wondering: would you use this script on the original image size (as it comes from the camera) or only for output sized pictures (for example TE with 800 pix in the longer edge)?

thanks in advance,
kristaps

The standard rule is to never sharpen an image until it is at it's final size.

well, looking at luko's script, it seemed more like a contrast booster than sharpener. that's why i was asking. i might be wrong though.

Actually it's both. The first part, 18/40 (or 10/20, or 15/30) is the contrast boost; I don't use it if the image is contrasty enough. The second part (two "passes" of the sharpening filter) is for the sharpening itself; again, I often do it at just 100 and not 150. And always on a separate layer to be able to tune it even more (by reducing its opacity, or by masking the sky or any other part, or by blending it in luminosity mode).
That WS mentioned by wjgmsppedy was mine, I'm afraid. Please feel free to ask anything you don't understand.
Regards,
Inés

Luko explains this method, but there are also more contributions.
