So I'm fooling around with ISO 50 - 80, and getting awesome results with  a lot more DR than I can get without this. Only problem is, a few highlights are pinkish. I look around and I find people saying this is normal and fixable in post, but I haven't seen anyones process. Is it just selecting the regions and CCing them? Is there a more methodical way? Any feedback appreciated. Thanks.

Looking around, I saw  that you can use  video limiter in premiere to correct this, and it works but seems like it slightly desaturates the rest of the image as well. Anyone know a better method?

Good news! So I have developed the following workflow.

FOR H.264 VIDEO WITH NEGATIVE ML-ISO:
Import footage to 5DtoRGB
Export to ProRes 4:2:2 HQ
Color Correct in Premiere, bring highlights until pink highlights are very obvious.
Videolimiter on Chroma, Highlight Compression, reduce Chroma Max until 1% Below level where pink highlights are no longer visible.

Finished, footage is clean.
