USM.. the big mystery!!

I am just getting the hang of this... my focus fell slightly on some recent photos and I wanted to get them back- the capture was so cute.. but how to make it look right??

well, use your USM in your photoshop. It's called UNSHARP MASK but it does seem to sharpen.. It has to do with how it was done in a real darkroom versus how we do it in a computer digitally. "It gets it's name because it unsharpens (de-focuses) the image and uses the difference with the original image ..." (this quote from Focus Magic)
there are 3 things to understand.
The first being amount which is measured by percentage.
The second being radius which is measured by pixels.
The third being threshold which is measured by levels.

I have some links to some sites and I would really like to get a discussion going on this great filter!!! What do you say?? are you ready to clear up some of your photos that are soft on focus??
