Why are the purples missing in my photo suddenly?

@Terry

Test your style on normal subjects and confirm it still functions correctly.

I do this all the time and it works on the large majority of photos. I admit that I sometimes struggle with the CC or white balance in DT, but this was the first time an entire color just completely went missing for me (and I couldn’t bring it back).

@mino

Do you have other photos, where you observed this behaviour? The shown image of the incredibly saturated blue wallpaper seems like a fairly artificial testing ground compared to other more naturally lit scenarios.

Sure, that’s a good observation as I have posted an image previously where I also photographed blue light and struggled with it.

@mino

What is the source of the left example in your original post?

Just delete the sidecar file and it will show up like that in lighttable.

@kofa

I do wonder if the original scene really had those purples, or if they are only artefacts of the camera’s own colour management. RawTherapee also shows no purples.

I posted a screen dump of the wallpaper I took a photo of a few posts up, so you can see the original purple yourself. My laptop does have a very saturated screen I’m not super fond of, though. I have no idea how to change the monitor profile on it (especially in Linux).

And thank you to everyone commenting so far, now I’m starting to learn things!

EDIT: Also, now that I’ve been staring at the photo for a bit more after sharing it, I regret not dusting off the laptop first!
