Related links, images and relevant information involving this howtube video.
A color mask allows you to precisely target each color channel in Photoshop. When combined with a Levels or Curves adjustment layer, this is a very powerful way to alter the color balance of your image. This workflow is great for nebula photos captured in H-Alpha Oxygen, although you can use it for any camera and filter combination.
Jimmy McIntyre has lots of great Photoshop tutorials, and his Raya Pro plugin is crucial to this workflow. We'll use the InstaMask feature to quickly create our color masks. You can find Jimmy's Raya Pro here:
