Here is a short video tutorial about how to create luminosity masks. If you haven’t heard about those masks yet, I recommend you head over to Tony Kuyper’s homepage.
He’s kind of the pioneer when it comes to the usage of those masks in Photoshop and he has an extensive set of tutorials on his site. You can also buy a set of Photoshop actions as well as an Actions Panel, which I also use for my post processing, there. But for those interested on how to create those masks from scratch here’s the video.
If you’re curious how to use those masks now, head over to my Start2Finish tutorial where I show how I use those masks.
