Reducing Highlights With DXO PhotoLab

Posted Sep. 29th, 2023 by Daniel J. Cox

Like you, I’m a long-time user of DXO Photolab. I’m currently using v.5 and have just downloaded a trial of v.7. My question is about your procedure to reduce the highlights. In my Photolab experience, when I reduce the slider, the file takes on a dingy grey tone, rather that diminishing the highlights as would happen with my old Lightroom program. Any ideas?

Hi Eric, Was the image you saw these issues in, when comparing results in both LR and DXO, the same file? Also, was that image a RAW file or a JPEG? I’ve noticed the issue of a “dinghy grey tone” when trying to recover highlights from a RAW file that is grossly over exposed. I’ve seen the same when trying to bring back highlights in a JPEG as well. Camera manufacturers often state it’s possible to recover two stops of highlights from an overexposed RAW file. I find that to be at least a 1/2 stop too generous. My experience has been that if I’m more than 1.5 stops over exposed and I have whites in the frame, they most likely won’t be recoverable. If I do try to bring them back the white area turns grey. Maybe that’s what you have been seeing?
