Just give it a try: Save a red surface with a blue square with 25% ten times. The thing is, that jpeg compression is supposed to try to guess what the eye is able to distinguish and what not. Some rest will be that distinguishable, that jpeg won't get smaller or worse anymore. ____________________________________________________________________________ darktable user mailing list to unsubscribe send a mail to darktable-user+unsubscr...@lists.darktable.org
