Lightroom/Camera Raw: Camera Standard profile for A7R III is terribly off

The Camera Standard profile Adobe has created for the A7R III adds a notable yellow cast to the image (unlike say Neutral or Vivid). Clearly not a match for the in-camera Standard profile when shooting jpg.Dear Adobe, can you please correct this?thanks

I'll repeat a previous post here: "no profile will fix metameric failure of the camera".

The profiles you create using the color checkers are only valid in the exact same lighting conditions as you shot the color checker. If the light spectrum changes in any way, it is no longer valid.

I would agree with you if it was not for the fact that the very same picture that I used to build both profiles looks different under the two profiles. Try the second link I posted, the shot of the CC passport "...004", then pls flip between the DPE and XRite single illuminant profiles and look at - say - the orange square at the bottom. Night and day.They cannot be accurate at the same time.

With the CC Passport next to the screen I have to say X-Rite colors are a much better match.

Again there is no right or wrong: only preferred subjective color OUTSIDE known measured reference solid colors (like on the Macbeth itself)!

But here we are INSIDE the known measured reference solid colors. We are discussing the rendering of the CC Passport. How can it be different? It is the same shot that I used to build both profiles.

What is the whole point of doing all this if they can't even match the colors from the same pic from the same camera? Let alone from different cameras and different pictures.

It seems to me this is a giant waste of time, I think the Adobe Standard after all is quite accurate and works in many situations.

I have noticed the same thing. The passport software produces profiles that generate better matches with the visual appearance of the color checker than adobe's profile editor and overall more pleasing color. I generally don't use Adobe's software for that reason. I remember reading that Adobe's software doesn't touch the tone curve in the final profile and just uses the curve embedded in the base profile you start with. Don't know whether my memory is correct.

So you can't just ignore the base profile you start with? I ignored that tab, I think by defaults the base profile is Adobe Standard and not the camera emulation one you used to shoot. Should you get better results using Camera Standard instead of Adobe Standard as base profile?

I'm surprised this topic is still going...

Here's a generic dual illuminant profile I made. It's not meant to match camera standard or anything and I can't promise it'll work right for you or your specific camera

Well, just playing with the profiles and comparing differences...

Thanks, for the profile, what software did you use to build it?

I've just discovered the root cause of the Sony A7R III camera profile rendering issues:

https://forums.adobe.com/message/10263842#10263842

It appears Adobe used a pre-production camera to create the Sony A7R III camera profiles. Apparently Sony made available a number of these cameras for test purposes with firmware v0.01. Images shot with these cameras look fine with the Adobe created camera profiles:

Production cameras with firmware version 1.0 or the later 1.0.1 version exhibit the rendering issues being discussed here.

Interesting. Hopefully Adobe will fix it once for all. Seems Eric Chan is on it.

Could someone please clarify if this color rendering issue has been fixed in a software patch yet, as currently thinking of purchasing Lightroom...?
Thanks,

This is just one particular profile that is/was off. Other profiles for the A7III are fine. I have this camera and I love the Adobe Landscape colors. No reason to base your decision on one profile.

I ́m still struggling with this issue.
My images present a yellow/greenish tint in the middle to dark tones, specialy visible in skin tones.
Also the color transitions in dark areas of the skin present an abrupt color change in certain tones oversaturating the yellow to orange tones and crating very strange artifacts in the blue chanel. The highlights and small specular whites are never clean of yellows making the hair look awfull...
Mosto of the time people I photograph looks like a Simposon character and trying to solve this with camera calibration just mess with any other color in the scene.
Adobe profiles are terrible, but the Camera matching ones are way worse.

In Capture One I tried other camera profiles and had better results with Canon 1Dx profile anda with Adobe DNG colorspace with bumped saturation adjustments.
