Camera Raw: Nikon Z50 camera profiles display strong (red) color bias

Similar to the first generation camera profiles for the Z6, there is a relatively strong red tint in the Z50 images. Most of time the tint value is set at >20 after importing NEF files and applying for instance the Camera Neutral profile. This has been solved with an updated v2 profile for Z6 cameras (https://helpx.adobe.com/camera-raw/kb/white-balance-issue-color-cast-with-nikon-z-6-raw-file.html) but apparently it has not yet been addressed for the Z50 camera.

Please advise.

Until/if Adobe makes the correction, you can create your own default settings and in those default settings you could make the appropriate adjustment.

Thanks, i've tried but the results are not consistent (because i suppose the tint values aren't linear). So sometimes, it's +12 (instead of the let's say +24), sometimes +2 etc. I.e., much less consistent than when starting values around 0 (such as it the case for the updated version 2 profiles for the Z6). But I'm not a software engineer and this is just my impression...

Hello. Please upload some sample NEF for us to examine. Thank you.

Many thanks in advance Chris. Here is the Dropbox link to three recent examples (NEF files) as well as the three same images after editing (as DNG files exported from LR Classic).

Hi Chris, were you able to reproduce - or even better, identify a solution - for the red tint issue with NEF files from the Nikon Z 50? Thanks in advance and best wishes from Tübingen, Germany, Steffen

Sorry for my repeated questions, do you please have an update for me?

Thanks in advance and best wishes from Tübingen,

I downloaded your images and looked at them. I am not an Adobe employee, and I'm not a particularly technical individual. However, I opened them in camera raw and I did not see any red tint issue. All images look well exposed and very natural to me.

Hi James, thanks. Are you referring to the PNG images (which were manually corrected) or to the NEF files when viewed in Lightroom Classic? When you're referring to the NEF files when opened in Lightroom Classic (or Camera Raw - which i suppose should give similar results), didn't you notice a strong red tint when compared to the final PNG copies of the same images (after correcting for the strong red tint)?

Especially DSC_0968.NEF displays an almost purple sky... doesn't look natural to my eyes (while the sky in the corresponding PNG does)...

I looked at all the images in Bridge, looked at the NEF files in camera raw and also in the Nikon software, NX Studio, and everything appeared natural on my computer. I wonder if perhaps you have a corrupted monitor profile.

Thanks James. This would need to affect on my side: 3 newer Macs, 2 iPad Pros and an iPhone 11 Pro... possible but relatively unlikely...

Maybe an Apple issue?

On the other side, a very similar, if not identical, issue happened with the original camera profiles for the Nikon Z 6 images (prominent red tint), which corrected in very rapidly released camera profiles version 2.

I am not a Mac person. I'm using a dinosaur of a Windows PC, and I'm a dinosaur myself. Not really someone qualified to make a real diagnosis of the situation. All I can report is that on my computer your images, all of them, displayed normally, no color bias whatsoever. And since I have no real computer expertise I will make no more suggestions or comments regarding this subject.

Dear James, thanks a bunch! ;-) No worries. Long live dinosaurs!

PS: there wasn't a single JPEG, there should be either NEF (raw) files and PNG files...

Just checking back. On my system The NEF files and the PNG files both appeared normal. So I really don't have any suggestions for you. Someone who understands Mac computers might have some insight.

Greetings @Steffen70 ,

I've spoken to Chris about this particular issue.  After evaluating test files and the files provided, it has been determined that there is not a bug here to fix.  

Note that the cast appears only in some picture controls and by extension, their camera matching profiles in Lightroom. Additionally, the cast is present in the camera manufacturer's software when using these picture controls. 

We don't find the cast present when applying Adobe Color profiles.

The good news is that it appears to be easily correctable by adjusting White Balance and/or using Adobe Color profiles.

This thread has been removed from the acknowledged status and set back to neutral. You can opt to turn this into a feature request for a change in the default behavior if you wish. 

I apologize for the length of time returning an answer to you. 

Thank for your patience and providing the example images.

Dear Rikk, thanks. I agree this is more easily correctable than for instance the other issue with the under corrected vignetting for Nikon now >2 years old Z lenses. It's still jarring though after using Lightroom for D200, D300, D700, D800, D750 and (with camera profile v2, also) Z6 where the tint tended to be rather around 0 and was thus much easier to correct. For instance, i know exactly what a +2, +4, +6 etc value does to my other NEF files - with the +16, +22 and higher with the NEFs from the Z50 i'm without any compass and therefore, spending A LOT more time per image to gauge a natural colour balance... but other than that, yes it's correctable (although may be not quite as "easily" as with all the previous very high quality camera profiles for Nikon cameras in Lightroom Classic). ;-)

Rikk I'm seeing a much higher saturation with the LrC 10.2 Camera Standard profile when compared to the in-camera 'Standard' profile applied to the embedded preview. It's easy to duplicate. Here's a link to the test file.
