Whites clipping to harsh blue color
My apologies if this is a begginer’s problem. I am grading some R3D files shot at 8K on a RED Helium. When I apply my grade to it, a strange blue color appears in the whites. I am looking everywhere at the program but cannot find what is causing this and how to eliminate it.
Before Grade:
After Grade:
Any idea on what is going on?
Thank you so much for you time.

What are your Raw settings? Are you using a LUT?
One workaround: use Soft Clip and reduce the Blue clip level.

My workflow is this:
Import the R3D files via XML, use the color match (an X-rite color checker passport was used on set), then grade.
I’m using project settings, but I tried all the color settings in the project settings, I tried switching the Red Raw settings, I tried black hole sun fixer, lowering the highlight clip in the curves.
It doesn’t seem to occur when I grade from scratch, not using the color match.

Well could you not use the color match in that case?
-
Yes that is a work around, in fact what I ended up doing is exporting it with this artifact and then selectively keying it out in premiere. Cost me a few hours but I was able to get around it.
I suppose I was just asking if anyone knew what is causing this and if there was a simple solution that I just overlooked.
I appreciate your time / response though!

You can selectively key out the problem just as easily as Premiere in Resolve.

There’s nothing done in Color Match that you can’t also do manually. All it takes is time and work, plus knowing how to interpret scopes and the monitor.

I’m certain that is the case – however I was stubbornly wanting to use the X-rite. I wasn’t able to key in out in Davinci even with another node. That was another odd thing.
I agree that I could just do the grade over, I was too deep to start over. I was hoping the was a simple fix other than not using a feature.

Also using the automatic color match to a target isn’t some magical one click done-sort of deal. If there are lighting/exposure/whatever issues with the target footage there can be all kinds of weird results.

Right… I was just trying to get to a balanced shot to start actually grading. What the X-rite is made for.
I guess maybe I wasn’t clear. I understand that I can grade everything from scratch, as I have been doing for years. But there is no reason for these whites to clip into a harsh blue color like this even using the color match feature. My hope was that someone would have a very obvious solution to this issue – perhaps it was a common one that I just didn’t know about not having used the color match feature.
So far the advice has been repeatedly – don’t use the color match feature which though I appreciate input, is not helpful in any way.
Has anyone else seen this type of artifact? Where whites are clipped into a very harsh color? Using color match OR NOT, since the solution may be the same. If so, what was your fix other than throwing away all your work and starting over?

Please do use the color match feature IF you know what you’re doing. There are some tips in the manual. I never start forcing my colors according to a target, but I will probably check out white, gray and black balance on it.
