Birdseye42 Posted December 17, 2019 Share Posted December 17, 2019 It would be good to have a graduated brightness adjustment. For example, I have a photograph of a group of people on a staircase taken with flash. Those at the bottom of the staircase are, of course, brighter than those at the top. It would be good to use a brightness or levels adjustment to compensate for the gradual loss of brightness the further up the staircase you go.

walt.farrell Posted December 17, 2019 Share Posted December 17, 2019 I think what you're asking for is already possible. You would apply the brightness adjustment, and use a gradient in its mask to control where the adjustment is applied, kind of like a graduated neutral density filter on a camera.

walt.farrell Posted December 17, 2019 Share Posted December 17, 2019 For example, here's one where I did that with a black & white adjustment, with the gradient running vertically so it applies progressively less as it goes down the image: The same could be done with a brightness adjustment, so it applies more toward the top of the picture.

Birdseye42 Posted December 17, 2019 Author Share Posted December 17, 2019 I thought there might be a way, Walt. Can you give me the idiot's guide on how to do that. Do I create a brightness/contrast layer and add a mask layer to that? Where does the gradient tool come in? Quote Link to comment Share on other sites More sharing options...
Birdseye42 Posted December 17, 2019 Author Share Posted December 17, 2019 Sorry, Walt - I think I've got it. Thank you very much for the tip - brilliant! Quote Link to comment Share on other sites More sharing options...
walt.farrell Posted December 17, 2019 Share Posted December 17, 2019 You're welcome. It was a bit of an experiment on my part, too, as I'd never actually tried it (But to answer your question, each adjustment has its own mask, and if you paint (or put a gradient) on the adjustment layer itself you're adjusting that mask, and controlling where/how the adjustment applies.)

Richard Liu Posted December 26, 2019 Share Posted December 26, 2019 Walt, Interesting. I'll have to try this. Do you know whether this works with live filters? I sometimes feel that I don't want to sharpen the background as much as the foreground.
