Unable to get good colors from a raw file

I am struggling with a photo taken under reddish light. We hade huge fires that destroyed forests: the wind carried the smoke in my direction so the afternoon light was very red.
I have tried Adobe Camera Raw and that program created an image with reasonable colors. I cannot get good colors from RawTherapee, even using the same Adobe camera profile: the colors are too saturated: if I print the photo the result is horrible.

Here is the Adobe Camera Raw result:

Here is the RawTherapee result:

I don’t know why but the in the browser the images are much less saturated, even if I converted them to sRGB. Anyway you can see the difference.

The raw file is available from here: http://www.fsoft.it/temp/P1140971.RW2

The Adobe profile that I used is available from here: http://www.fsoft.it/temp/Panasonic.DMC-GX7.Adobe.Standard.dcp

Thanks in advance for your help.

I think you ask for a neutral colors, so I have tried to (completely) remove the red cast:

  • maybe one of the problems was the amount of fringing everywhere, which adds some warm look, so some defringing has been applied
  • I have picked a neutral patch from the grey window, and almost all the reddish cast has gone (maybe too much for your taste?)
  • I’ve had to play a bit with the Exposure tool so the khakis didn’t get clipped, but there is enough overall light and contrast in the picture
  • no noise reduction or any other tool applied, so you can work from here to where you like it most

You may wish to search for color management and RT profiles in this forum, too.

just using the adobe DCP in Rawtherapee

@XavAL - Nice job. Of the replies posted, yours is the only one that isn’t too yellow. Color is such a subjective thing - unless you were there, who can say? Even if you were there what you remember v. what you wish to remember can be 2 different things.

Thank you for your answers.

The image has to be red since the light was very red.

My problem is that if I open the image in Camera Raw the colors look right. If I open the image in RT, with the same profile used by ACR, the colors are too saturated.
I am looking fo a way to get, from RT, colors similar to ACR’s.

@age you image looks really good. I used your PP3 file and the result looks very similar to the one from Camera Raw. From a quick check it looks like you enabled the tone curve in the dcp profile and disabled the auto matched tone curve in the exposure panel.

BTW, it would be very handy to have a tool to check the differences between pp3 files in a readable way…

Take a look at Meld: it’s a diff tool to show differences between files. It will be as readable as a pp3 file is, though

I think, there is just some yellow cast in your RT image. Besides that, the RT version has a little more (local) contrast, which I actually like.

Below you see a comparison of CR (left) to your RT-JPG (right) in which I reduced the yellow “zone” in saturation using the color zone module (darktable).
