What is USM? Everyone talks about it. I'm assuming it's a PS tool, so how do you work it?
Thanks! |

USM in photoshop is a way to increase image sharpness... it was inherited from film processing and thats why it got its name..

USM in regards to editing is "unsharpen mask." See the following tutorial for a good explanation as well as instructions for implementing it: link
Also, I think the Canon version of USM is Ultra Sonic Motor. :-)
