The preview says it all.
This action is built to remove the digital grey (lack of contrast or true black) that comes with HDR photography (or normal images could use this as well as a one click fix). When combining many photos to extend the dynamic range, the contrast curve can become very flat and even reverse. Modern programs are getting much better at handling this problem but I still will apply at least one of these actions to my final work before submitting to my clients.
New set has 4 actions, HDR Fix light, normal, heavy and Clicker.
To use Clicker just keep clicking play until you get the desired level of the effect from the action. I recommended using the HDR Fix Light action as the last step after using click pop.
The more grey (lack of contrast or true black) the photo has the heavier action you should employ.
