Removing Color Aliasing
Here's another quick trick Jim DiVitale and Kevin Ames use for reducing the color aliasing (digital noise) that often appears in digital photos shot in low-lighting situations.
Open the photo that has visible color aliasing. Go under the Filter menu, under Blur, and choose Gaussian Blur. Drag the Radius slider all the way to the left, then start dragging to the right until the color aliasing is blurred enough that you can't see it. Click OK to apply the blur.
Go under the Edit menu and choose Fade Gaussian Blur. When the Fade dialog appears, change the Fade Mode to Color (as shown) and the color aliasing will disappear. It's quick, it's easy, and it works. It's also an ideal candidate for becoming an action, so you can remove color aliasing with just one click.
