This is my most popular action that I have created to date with over 500 comments, 1,500 favorites, and over 410,000 downloads from when I originally posted it on Deviantart.com
It works best on photos that have high contrast to begin with, but enhancements can be made before or after loading the action. It features a unique gradient map, and blending layers to enhance photos.
I like to load the action and duplicate my original image and adjust the opacity to blend the result – depending on if I want something more natural or if I want something dramatic I will leave it as is.
