I noticed this while editing some very dark night photography images that were the product of trial and error. Upon importing them to RT I noticed a ton of noise on the photos but could not seem to revert the file back to its’ original form.
I’ve been scouring the interface trying to find a Preferences tab that shows me a ticked box, beside which the text reads something about automatically adjusting something, somewhere. It has been annoying because I can only remove so much noise with Dfine!
