Description

I use darktable for my RAW image processing, however, sometimes the color is wrong in darkroom.I found it in darktable_2.0.3 with Ubuntu 16.04.2(64bit), and i've tried the latest darktable version(2.2.5), the following problem is still there. Please help check this, thanks in advance.

As is shown in the attachment geeqie_vs_darkroom.png, with image displayed by geeqie(with color management) on the left, and image displayed by darkroom on the right:

image displayed by geeqie is Okay, and it aligns to what's shown in my camera.
image displayed by darkroom has some problems: high saturation/contrast, some color is even wrong(as is shown in the top right and other areas)

In most situations, darkroom works fine for me, however, this issue makes it impossible to process the image sometimes.

please help check the issue above, and help fix it if it is really a bug.
thanks in advance.

First of all, geeqie is showing the embedded JPEG preview and not the real raw data. So it's supposed to look the same as what you see on the camera display.

Second, you have ActiveDLighting enabled in your camera. That is doing some post processing in camera and results in the JPEG looking different than the real image taken. I guess in your case that's the reason for the difference.

Hi Tobias,

Thanks for your help, but I'm afraid that I donnot totally agree with you.

I made a test a moment ago. The difference is still there even when I turned off ActiveDLighting in my camera. The test result is shown in the attachment.

Would you please help re-check this issue? Thanks again.

That difference looks minimal to me and is probably just the expected difference between camera processed JPEGs and raw files. One thing you could check is the display profile setting in darktable. In order to make sure that it's not the color management you can set it to sRGB in darktable and disable display color management in geeqie – does it look closer than?
