Tip of the day: 30-second Photoshop Noise Buster

Here’s a quick and dirty way to get rid of color noise (that’s the nasty variety that most messes up the shadows) while keeping the detail—no fancy filters or plug-ins required. Duplicate your noisy background layer. Go to Filter Gaussian Blur, and blur it until all the colors run together and you can’t really see the details anymore. Then switch the Blend Mode to Color. The result: Noise goes, detail stays. (from December 2008 Picture Doctor)
