I have a B&W pixel layer that I have converted to a mask layer and put inside a live adjustment layer. I decided that I want to boost the contrast of the mask after I had put it into the live adjustment layer. How do I do that? Preferably non-destructively such as adding the Levels adjustment to the mask for more control. If not possible I'm still happy with a destructive method too. In Photoshop I just ALT+CLICK on the mask to make it active and then CTRL+L to adjust the Levels of the mask.
