Reflection Removal in LRc, does not seem to work on Sony ARW files. It does work in Photoshop/ Camera Raw, but not in the latest version of LRc. Anyone seen this issue?

I have been underwhelmed by Classic reflection removal. It doe not live up to the hype. I have not tried it in PS. Thanks for the suggestion

“Sony ARW files” can be from a large number of cameras. I can’t speak for all of these, but it does work fine with files from my Sony A7R V camera in Lightroom Classic 14.4 on my Mac.

What kind of pictures? It works best on plate glass, rather than curved glass like spectacles.

That sounds like a bug. Upload a problem .arw to Wetransfer, Dropbox, Google Drive or similar free service and post the sharing link here. We can file a bug report if necessary.

Doing some tests just now on a sample raw, I noticed significant differences in Reflections between CR 17.4, 17.4.1 (released a a month ago), and 17.4.2 (released today with Photoshop 26.9).

Update to PS 26.9 and verify you have CR 17.4.2. Do you still see differences between LR 14.4 and CR 17.4.2? If so, share a problem raw as described previously.

I have tried Reflection removal on several “textbook examples” of Nikon NEFs. The results have been poor compared to the advertised examples. I am away from my home computer and PS26.x to compare. But I will do this at first opportunity.

There are other threads where I posted examples of the poor implementation of Reflection removal. If you want to look them up.

It's not perfect by any means but I rather like it. A polariser restricts light polarised at a selected angle, allowing the remainder of the light information through. This is vastly different. It has to identify a reflection, no easy task, remove it then generatively rebuild the space left, guessing with what little real information was left. I was recently at a croc jumping boat tour on the Adelaide River, Northern Territory. I had to shoot through glass and didn't bring a polariser. Reflections were easily removed. It helped that most of the images had a relatively featureless water background and I was shooting from inside a cabin to the sunlit outside. On the other hand, shooting through a shop window from the outside, at a complicated display was not successful at all. I also find it useful for water scenes where it gives a sense of depth like a polariser except unlike a polariser, you are not actually seeing into the water.

Thanks guys on further investigation, some worked and other did not. So I eventually realised that those that did not work had the wrong camera profile, Nikon rather than Sony. Now all the offending pictures are available so be modified in the distraction removal panel, with the correct profile updated. So I assume CR does not use the profile when transferred from LRc?

John I have both CR and PS and the current version and do not see any differences.
