I have used darktable previously and this just started the other day.

I imported a raw image and when I change anything (exposure, contrast, etc) temporarily the preview I get from darkroom is what resembles to the jpg photo. If I zoom in and out the image goes back to raw...

This is very strange as I cannot see what is the effect of whatever module I change.

I am using darktable 2.6 on windows 10. I haven removed and installed darktable.


I did a system restore and the program got back to how it was in the beggining.

Today I got the same issue as before, still could not figure what is the problem.


Not only the colors are very different the histogram varys without anything being chaged. See images.

The contrast block changes inconsistently the histogram. And again the image color is wrong

    Nit: you are never looking at the raw image. You are always looking at a rendering. How that render is generated and cached is a different question, of course. – user31502 Jan 15 at 14:58

    I think this is more of a bug report than a question. For what it's worth, I can't reproduce this behavior on the Linux version. – junkyardsparkle Feb 17 at 23:42
  • FWIW, I'm getting the same issue - same setup as the OP (2.6 and Win 10). Am using half-RAW preview rather than the JPEG, as well. – user82573 Mar 10 at 2:41

Darktable has a couple options that influence which image is displayed when. Check your settings, in particular the one that says "don't use embedded preview JPEG but half-size raw" under "GUI options".

  • I have done that, but still get what it looks like the JPEG image preview and then if I zoom in and out again back with the RAW – Henrique Silva Jan 18 at 15:42
