Double USM 2

Multi-radius Sharpening plugin for Photoshop

Multi-radius Sharpening plugin for Photoshop


Double USM 2 is about sharpening, i.e. all the tricks we use to turn images into razor sharp sources of gorgeous detail.

Whatever fancy technique you happen to use for this purpose, the goal is to visually enhance the edges of your picture’s subjects. Chances are that you and your Sharpening filter are doing so injecting halos: dark and light ones.

Halos are created setting three parameters: Amount (intensity), Radius (thickness), and Threshold (noise control).

The UnSharp Mask filter and its descendants cannot discriminate the control of Light and Dark halos. They’re created equal. Which is not so cool: super-experts like Dan Margulis, pooling a large number of professionals over the years, have found that Light Halos are the ones giving the feeling of oversharpening ? the cardinal sin of the post-producer.

Double USM 2 is to the rescue: you’re allowed to selectively control Amount, Radius, and Threshold for Dark and Light Halos separately. Better, sharper images! Plus, you have advanced preview options and Presets.

What for? Tone down Light Halos on Traditional Sharpening, use better HiRaLoAm (High Radius Low Amount) to enhance the local contrast, or mix Traditional and HiRaLoAm for creative purposes.

Double USM 2 is a Panel that drives a C++ plugin, internally working with 32bits precision.

It supports 8bit, 16bit and 32bit (HDR) images, on Photoshop from version CC up to CC 2017, both Mac and PC.

2.0.0 - Feb 2017
First release of the 2.x version.
Double USM 2 is the successor of Double USM, a Photoshop Script that I’ve first published in 2013. The technology behind it is completely changed (HTML Panel + C++ Plugin): that’s the why you find it as a new, distinct product.

Double USM 2 is compatible with Photoshop CC onwards (CC, CC 2014, CC 2015, CC 2015.5, CC 2017 and following versions). It does *not* support CS6 ? please use Double USM first version if you need backward compatibility.

Please find Double USM in the Windows > Extensions menu
