Hey guys, late last year I bought a P6K to work alongside the Alexa I normally shoot with. The goal was to have smaller, lighter camera that would live on a gimbal or could be used in situations where

After many requests, P4K2Alexa PowerGrade + LUTs coming in the next day or two. Dawn to dusk, one PowerGrade, no adjustments to the transform.

I have BMP6k footage we shot with two ND's stacked that caused really bad IR pollution and blue channel issues.  Do you have any idea how to correct ?

It could be pretty difficult to correct.

I would start by shooting an outside scene with and without those filters. Use shutter speed to compensate for the lack of ND on the unfiltered shot. Take both into Resolve and use temp and tint to get as close as possible to the unfiltered version. Then use the RGB curves to correct any non linear differences. And depending on how bad it is you might need to use hue v hue, or even qualify and correct specific colours.

That's going to be tough if not impossible to correct completely.

If it's a short video I would look at qualifying and using shapes to isolate and correct as much as possible. If it's long, I would probably see how far the first methods I suggested could get you. Followed by making it B&W. And if that isn't acceptable I would look at reshooting.
