Lightroom/Camera Raw: Nikon Z7 RAW processing and White Balance

A couple of problems with the camera profiles for the Nikon Z7.

1. When changing the white balance from "As Shot" in Adobe Lightroom or Camera RAW, the program creates a magenta cast on all Nikon Z7 images. This is true for all Adobe white balances and all the camera white balances. Returning the Tint slider to its original location removes almost all the magenta cast that was introduced. I believe this was an issue that was fixed for the Z6.

2. There's something wrong with the way that Adobe is reading or applying the Built-in Lens Profile. It seems to apply the corrections correctly for the Z lenses, but when using adapted F-mount lenses the profile isn't applied even though Lightroom claims that it is. If you manually apply the profile for the F-mount lens, it gets applied correctly. This also impacts stitching in panoramic photos. I can get a perfect stitch from a D850 with the same lens whereas using the same properly adjusted for the camera/lens RRS pano system and same lens with a Z7, the stitch is poor. It gets better after manually turning on the lens profile for each image in the stitch.

Running the 8/14/19 release of Lightroom Classic/Camera RAW.

hey! i'm so glad you report those issues, i have exactly the same problems with my Z7 and LR. i had hours of chats with adobe tech support, but in fact they named me an idiot and no one in the world would have reportet such an error...
regarding 2) switching on lens profile correction does exactly nothing, i'm experiencing vignetting of about 1 stop in the corners that isn't corrected.

I've asked the Camera Raw engineer to review this thread. Please stand by. 

I spoke to Chris on the Camera Raw team and we'd like to collect a couple of files that exhibit both the White Balance issue and the Lens Correction issue. Please include all information about your system and step-by-step instructions for inducing the behavior.\

Would you like these files sent from anyone with the Z7 white balance issue?

I will send him my files when I'm back in my office tomorrow. I've been teaching a photography workshop, so I haven't been to the office since Thursday.

I have all of the above issues with the Z7, but in addition to the tint, the temp is also visually off by about +200K. I discovered this by comparing the same scene of a grey card shot with a Z7 and a Z6, using the same lens. It may be small enough to go unnoticed because of the magenta tint. Could you guys check your photos again and verify this?

Another thing to note is that in this grey card test both the Z7 and Z6 were set to 5000K in camera, but when importing to Lightroom, the As Shot values for the Z7 are 4600K and -13 tint, for the Z6 they are 4800K and +7 tint, a difference of 200K and 20 tint. The white balance is visually the same for both cameras in these differing As Shot values. When I set both to Daylight, they are visually different, the Z7 showing as warmer with a magenta tint. When I use the eyedropper tool to set the white balance from the same spot, I get visually correct white balance on both, but the Z7 values are approximately -200K and -20 tint compared to the Z6, varying slightly depending on where I click.

The issue is obvious with the Z7, but what I wonder is that is there still a problem with the Z6 as well even though it was supposed to be fixed, since the As Shot white balance value does not correspond with what is set in camera?

Another data point: a picture taken with "Daylight" White Balance on my Z7 shows up as 4800K / Tint -15 in Lightroom Classic 8.4.

And, taking a picture of a gray card in direct sunlight, then using the neutral gray picker sets the temperature to around 5200K / Tint to around -15.

Issue: Lightroom has incorrect WB values for Nikon Z7 camera when camera is set to "Direct Sunlight". The Z7 settings (WB settings and values) were verified using Nikon software, so issue is with Lightroom.  Lightroom handles the Nikon D850 properly with the same settings (WB set to "Direct Sunlight").

This reply was created from a merged topic originally titled Lightroom problem with Z7 WB when camera set to "Direct Sunlight"..

Lightroom problem with Z7 WB when camera set to "Direct Sunlight". When the camera is set to this mode, the values for kelvin temperature should remain constant. In Lightroom, for this camera, the values for WB (yellow, blue, magenta, green) vary when the camera is set to "direct sunlight". The Nikon software verifies that the values should remain constant across all photos based upon the camera settings.  The settings should remain at 5150 Kelvin.

Hi,
I have exactly the same problem. My "0" at the tint slider in LR is at -18. Since I am only shooting raw, I never set the white balance in camera or switch between picture profiles. Iam a professional Nikon shooter since many years and I never had this Problem before the Z7.
The problem is, that Iam very used to set my tint and WB in LR only by Numbers and not by my one eyes. After editing 1000s of pictures, it's kind of burned into my brain which number to choose for specific scenes. It kind of goes automatically.
But now I always have to calculate those -18 into my adjustments for each picture.
That is a huge problem for my workflow. I had to use gray cards and the eye dropper to trust my editing.
If I use a colour sheet to create a present in LR the "0" colours are completely different compare to the imported RAW files.

I tried capture one and I am actually very close to switch.
Lightroom needs to fix those problems fast.
And saying the reason for that is to match the results between jpeg and raw is just completely wrong.
If I would be interested in jpeg I would shoot with my phone and not with a 3000 dollar camera....

Is there any solution to this problem? I have this issue when copying and pasting settings from a D500 file to my Z6 file with the "Treatment and Profile" box checked

The Z6 file looks pretty close but after I pasting the settings from the D500 it will become magenta and requires about a -30 point correction in tint. It seems like is an issue with the profile because after pasting the settings and having the color shift issue I go to the Profile dropdown and select any profile (even the one currently set) and it reverts to the normal color.

The profiles are specific for each individual camera. I don't believe you can paste such as you describe.
