This photo of God’s Window in South Africa near Graskop and Hazy View (!) was shot too late in the morning so the scenery was hazy. So I tried “haze removal”. But the result is that the colors in the exported jpg are different from the colors in the darkroom view”. Below you will find screen shots of the exported image and the corresponding darkroom view.
You may consider checking “Lighttable/Global options” first. You might have changed something there without noticing.
Or, you can open and save another photo (with similar colors, with just a basic processing) to see whether it also shows the same abnormality.
I’m not certain that it isn’t a color profile issue but I have never had any wish to change the color profile settings since everything was working fine (apparently) using all other tools. Color profiles are a hard subject to fully understand. After having experienced the problem and before posting I have studied the manual and looked through the settings without succes.
My settings are the following (pls let me know if I have left out some settings):
Your file format setting is 8 bit jpeg with a low-ish quality (73).
That may be too low to reproduce the colors you saw on darktable screen.
As an example, my settings are Tiff, 16 bit. Just a thought.
I have also tried it with JPG quality (100) and with Tiff (maybe this was 8 bit can’t remember) same result. I think that the differences are so big that there must be some other explanation.
Here is another example. Almost no editing is taking place except for haze removal (just to demonstrate the effect) and output is 16-bit TIFF. I also upload the xmp.
Look at the result using RT 5.5. for haze removal below. The RT editor view and the JPG are very much like the TIFF in the latest example. So it seems to me that the darkroom view could be wrong?
Haze removal will darken and alter colours as you see in your export so maybe the display while editing is not updating correctly to diplay the effects of the filter…not sure why that would be though…
Thank you for many responses and ideas, but no solutions or explanations have materialized.
I have installed 2.6.2 from scratch on another windows pc running only default settings. Same problem.
I will upload the photo and the xmp. I hope that some of you will test to see if the problem exists on other platforms and systems………?
Yes, I know and I have given it som thought. The blue sky is not out of gamut in the darkroom view and yet the color of the sky is changed a lot in the exported image?
