Luminosity Masks
I use luminosity masks to apply dynamic contrast very often, at times the level and window sliders don't produce my desired results. I've found that by brushing on a luminosity mask with 100% feather, 25-40% opacity preserves the lumen values but changes the local density.

Hey James. I've read you post a half dozen times trying to understand what you're trying to do. I sounds like you're trying to brush the luminosity mask in or out but it doesn't work that way. When you brush on a luminosity mask, you actually change the mask by adding or suntracting whatever the brush is set at.
or, have I just totally misunderstood the problem?

Hi Rick, I'm not certain about James .....
The steps I use wrt luminosity masking:
- create the mask
- adjust the sliders to reveal or hide to my liking
- if that fails I choose to brush at 100% feather and 35-50% opacity painting directly on the mask
- maintaining the lumen detail but changes the how much.

Peter, I did a quick test to see how luminosity mask and painting interact just to see if I understand it properly.
The way I see it, painting changes the mask. The only reason you still see detail is because you're using 50% or less which means that the luminosity levels in the painted areas are reduced by 50% there is still some detail but it's not preserved. The reason I say this is because if I painted OUT on a L/M and the mask wasn't changed, then I should be able to paint IN and reverse what I just did. It doesn't work that way, once it's painted OUT it's changed and you can't get it back without redoing the L/M. Try it at 50% and then switch from IN to OUT 3 or 4 times and you'll see what I mean. Eventually the entire area will even out.
