In short

Double USM is about Sharpening, i.e. all the tricks we use to turn blurry images into sources of glorious detail. All sharpening filters in Photoshop inject artificial halos but can’t discriminate between dark and light ones – they’re created equal. Not-so-cool, as Photoshop Hall of Fame’s Dan Margulis found out pooling hundreds of professionals: light halos are the main“oversharpening” cause. Double USM to the rescue. You’re allowed to control Amount, Radius and Threshold for Dark and Light Halos independently. Better, sharper images!

More about Sharpening

Everything you need to know about halos in this short and light-hearted video that I’ve recorded for the previous version – concepts still apply 100%.


Forgive me for being heavy-handed, it’s hard to appreciate the level of increased Sharpening on a website.
