Hi All

Having not found a forum search facility here? I hope someone can through some light (no pun intended) on the following.

I have read variously that most advise doing the resize and all other editing actions then USM as a final step. But there were one or two that suggested that the USM could be applied earlier in the workflow i.e. after the "main" actions e.g.colour correction, curve etc but before resizing.

So, what is the best advised workflow for these key actions - resize > sharpen or sharpen > resize? Apart from cropping & rotation these are all I have been concentrating on at the moment. And would the same advice apply if you were doing more complex work with filters and other actions?

TIA

Actually my sig has the link to the dpc search.

I use unsharp mask twice, actually. Once near the beginning - if I need some kind of noise removal as well. Then after the resize, a final "touchup" USM.

Hi Mavrik

Thanks for the pointer, will check out the links as well.

I use PSP (now version 8) I would have thought that 2 uses of USM would create more problems than it removes? Could you give some guidance as to the amount of USM (settings) that you might typically use as your starting levels for the steps you mention.

In my, so far, limited usage of USM I have already found that "soft" edged subjects like flower petals need different settings compared to subjects that have "harder" edges. So, if it were possible that such guide lines exist as a starting point in "typical" situations that would be of help!

Thanks again :~)
