What do a cave and a monkey have in common? Nothing.

I set aside my Oly EM-10ii after 10ish years, and bought a OMD E-M5.
– I really like the OOC jpgs more!
– It will aggressively boost the ISO when in auto, compared to the conservative em10.
Lots of learning to do here. But it rained on me 90% of the time we were in Spain, so the weather sealing was terrifying and incredibly useful.
Anyways…

I don’t know what I am doing. I pull a string on the modules, and watch what it does to the picture. Repeat dozens of times, and sometimes I am happy with the result. But with the new RAWs, I am hitting a problem consistently – there seems to be a slightly green tinge to my raws. I generally try to replicate the OOC look just to practice with darktable, and then improve from there. But in many of my photos, the raws are just frustrating me. (Yes, i tried the built in style, same problem but worse).

It is a green? tinge, and it uglies the blue sky and my monkey loses his glow. I keep going back to the color calibration module, but I am not sure this is the right thread to pull. Or, i am on the right track but doing it wrong…

Anyways, I would love a pointer on how to re-glow my monkey. And the cave picture has the same issue, but even more pronounced.

As for the cave colors, it’s hard to tell if there are dominant

Concerning the green (yellow?) tint, a hue shift of -8° your edit might improve it (color balance RGB).

My version of the monkey.

I wonder if using the green attentuation sliders in Sigmoid help with the green shift you are noticing.

Hello,

I think it’s best to use an input profile for your camera, as Darktable doesn’t have one and uses a generic one. darktable user manual - input color profile
Here is my proposal with an icc profile made with Dcamproof.

I wanted the background to be a little less distracting.
Cool monkey, thanks for sharing!

I made a one click change from my prior post, using Color Equalizer to give it a Kodachrome 64-like emulation.

I think I went down the ICC path a while ago. I had color cards, all sorts of test images, and it all accomplished NOTHING useful.

Thank you for the file you provided - It seems to have been EXACTLY what I was needing. The one piece of the puzzle that may make life with darktable suddenly easier? Or I will overuse it while not fully understanding, like curves and color calibration!
I experimented with lowering greens via the other methods listed here - I appreciate the inputs. I got so overwhelmed by the options, I forgot there were simple ones.
Anyways, my monkey looks like what I remember. He is glowy.

In the monkey shot, the raw shows a green cast:

1 EV more than red; 1/2 EV more than blue.

Converted in RawTherapee (AmAze) floating 32-bit ProPhoto, the raw green cast goes away.

Didn’t Play, just looked …
