I've really fallen in love with this plug-in and if you've looked through my pictures you'll often see "sharpened with FocalBlade". You don't have to have Photoshop to use it. This is a list of all the programs it will work with. FocalBlade does much more than sharpen. It also has a soft focus option.

I have NO financial gain from this recommendation! I just love the product. By the way, the screen grab is from the 40 page manual
