Ok, I finally figured out what is happening: For my understanding, I can't compare the pictures from darktable with another image viewer, instead I do a 1:1 ratio comparison, otherwise the picture can be very different. Depending on the software's algorithm used to display the image, it will interfere a lot in the image visualization, and, for what I have read, and after doing 1:1 comparison between several exported pictures and using several image viewers, I got the same results, but again, only using a 1:1 ratio. Otherwise the pictures will be very different.
I also did an experiment using another RAW editor (AfterShot in my case), and I got the same problem, AfterShot shows a different image than the one exported, unless I do a 1:1 ratio comparison. Now, I have a question if somebody can give me a help with. How could I work on an image and be sure that what I see is exactly what people seeing my photo will see? As I said I'm quite new on photo editing, and I'm struggling with it :) doing 1:1 comparison is not always feasible, or at least doesn't sound feasible for me all the time, but maybe I'm wrong and should always edit RAW images in a 1:1 ratio :) Cheers, and thanks for the help until now On Sun, Feb 14, 2016 at 12:57 PM, Carlos Maiolino <cmaiolin...@gmail.com> wrote: > BTW Patrick, how are you comparing both images? > > I've been using Image Viewer to open jpeg files, not sure if this make > much difference.
