Hi Terry,
Good to see that I am now getting notifications from the Forum when there is a new post. Maybe a photo critique forum would be viable now that this has been corrected!
Regarding your question, I just updated LRC this morning and found the new “Denoise” button at the bottom of the Detail Panel. It seems to only work with Raw images, in my case .ARW. It doesn’t like .jpeg or even .dng.
I did a quick test and it does seem to help remove noise with one AI click.
However, I compared the result to Topaz Photo AI, and found the result to be significantly lacking compared to the Topaz result.
Hope that helps!
Herb
