I'd love to see an X-T3 version! Instant purchase for me. Cheers Same here and +1 on the XT3 Chris Quote Link to comment Share on other sites More sharing options...

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 ?

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.

Juan Melara Posted March 31, 2020 Author Share Posted March 31, 2020 Hi all, after several requests I've now updated the P4K2Alexa and P6K2Alexa PowerGrades with new ACES versions. This allows you to match the Alexa when working in Resolve's ACES colour science. It's a free upgrade, get in touch if you never received your update email. heart0less, MoroZ and Gregormannschaft 3 Quote Link to comment Share on other sites More sharing options...
