Color Noise Removal in Photoshop

Recently while deep into an all night processing session, I ran into a pesky issue that I've experienced before, but never found a good solution for. When photographing at high ISOs, image noise is a common problem that rears it's ugly head in two ways- luminance noise (grain), and color (chroma) noise. I've covered dealing with luminance noise in other tutorials, so in this guide I'll be covering a method I discovered to clean up color noise in Photoshop. 

  For this method, you'll need experience working within Photoshop using layer masks, a luminosity masking panel (I highly recommend the
TK Actions Panel), and at least a basic understanding of how to work with luminosity masks. This is a very precise method of selecting effected pixels, and neutralizing the color shift apparent with color noise.
