Sorry, if it's silly question - but I noticed the problem only recently, and after digging around found these threads explaining roots of the problem:
https://www.reddit.com/r/photography/comments/3q8q7o/purple_noise_in_shadows/ https://www.reddit.com/r/photography/comments/3q4tnz/how_to_correctly_push_5_stops_with_canon/ Not sure: have suggested there software tweaks been implemented into Darktable already? Anyway if not - it could be worthy... it seems most of the software - including Adobe's LR - handle Canon's RAW files not quite correctly - that's why there are problem with unusual shadows' colours while pushing. -- regards, Zbigniew ___________________________________________________________________________ darktable developer mailing list to unsubscribe send a mail to darktable-dev+unsubscr...@lists.darktable.org
