Lightroom/Camera Raw: Fuji GFX Raw File White Balance Issues - Magenta Tint

Done

Thanks Rikk!

Yes - that thread is full to the 150 post limit, so I'll start a new one.

I've got them attached to the bug. I won't be responding to the DP Review thread - Can you let them know we are looking into it?

Hey Rikk - many thanks for taking interest in this one.

RAW + JPEG here: https://www.dropbox.com/sh/jp1sdcfwfjj6bhc/AAAmREz8Z22IcroFnp3VFBF6a?dl=0

This is a Fuji GFX in camera aspect ration crop, so you'll need JPEG and RAW in the same folder for ACR to see the JPEG crop and apply it to the RAW file.

Let me know any questions you have - and FWIW this issue appears to extend to other Fuji X Series models as well, so may not be GFX specific.

Greetings Chris, 

Would you be willing to share a file with us Preferebly Raw + JPEG so that I can attach it to the bug report?

FYI, I will be cross-referencing your DP Review Thread as well. 

I never shoot Adobe RGB for work, only sRGB. So I'm not interested in doing AdobeRGB based comparisons. This may be a specific sRGB issue, so I'm not interested in making the issue 'go away' at the expense of using a different color space.

Just keep in mind when comparing ACR RAF renderings it uses ProPhoto RGB. If a specific area of the image falls outside of sRGB gamut it will look different in the sRGB  JEPG. For the CC Graycard shot using sRGB is OK as long as the WB is set correctly in-camera.

There were no other camera settings applied to the motel image, no custom WB or tint adjustments. No custom settings to the JPEG, as I never use them. The only reason one exists with the Motel shot is that the camera insists on generating JPEGs with the RAW file when you're shooting a cropped camera view.

I believe what you're saying and you should post that raw+JPEG pair as well for examination. Was this an in-camera crop setting or still shot taken with the camera in video mode? It may be an entirely separate issue.

It's interesting that you keep using embedded JPEGs, and see nothing, where as I use the camera generated full resolution JPEG and see differences, and they are always skewed the same way. Small differences are important, minimizing them is not helpful.

Currently the embedded preview is all I have to compare! There may be something different about the camera embedded preview, which is why I am requesting you shoot the controlled raw+JPEG test shot.

I have a fully calibrated monitor, and it get's recalibrated monthly, so I don't believe your monitor profile theory holds water. I see the effect across multiple computers and screen btw.

Chris why so defensive. I said "it can also be caused by an incompatible monitor profile," which is not a theory. Troubleshooting is a process of elimination. I didn't say that was  the cause here, which remains undetermined. The fact that you see the same issue across multiple computers indicates it's probably not the cause.

I'm only seeing a 1 unit Tint or Temp difference between your raw and in-camera JPEG, but even the 2 unit difference in your screenshot is very small. I know you mentioned that this is happening with all Adobe camera profiles, but it's important that we compare the same in-camera to ACR settings. To do that you need to set the camera to Adobe RGB and Provia/Standard so that the JPEG has these settings applied to it. We can then set the raw file to Provia Standard camera profile to match the JPEG in-camera rendering. That's what I did in my screenshot showing the Embedded Preview, RAF file, and JPEG export of the RAF file. In my composite shot there is 0 difference in Temp and Tint.

The larger WB differences in the 2nd picture of the motel may be due to other in-camera settings. Many in-camera settings are not read or applied inside ACR/LR, which can cause significant difference in the raw rendering compared to the in-camera JPEG file. These raw to JPEG differences can also be caused by an incompatible monitor profile.

Given these small differences the best way to determine what's happening is to do a controlled test shot of the ColorChecker Grayscale card. Set the camera for Adobe RGB, Provia/Standard picture, Highest Quality Full-Size JPEG, and all other picture style controls set to 0 or OFF. This will most closely match the RAF file rendering inside ACR/LR when it is set to Provia/Standard camera profile. It would also help to set the camera's WB as close as possible to the actual lighting condition. Then post the raw+JPEG file pair to Dropbox for comparison. This will help us both to determine what's wrong and get it "fixed." Thank you!

Here's a good example where I'm having to shoot RAW + JPEG in order to do the in-camera pano crop. You can see the ACR version has more magenta, neutrals like the sidewalk go magenta in color for example.
