ND Filter Color Cast removal
Posted: Sun Feb 07, 2021 10:42 pmDear all,
it's late here in Austria and I've worked hard to get a certain ND filter greenish Color Cast removed, that shows up in the corners of Super Wideangle Lens footage shot among other footage at a Snow covered Valley.
# Camera: DJI X7
# Lens: Laowa 9mm/f2.8 (it's a Hot Swap with that manual Laowa Lens usually from the DL 16mm/f2.8 so it says that in the EXIF, in case one wonders)
# footage: Cinema DNG 5.6K
Thing is, I managed to get rid off the Cast in Premiere CC relatively easily by creating a Vignette, and then desaturating that Green cast within the Vignette's area with a soft setting (it's the Area where the ND Filters green cast is visible) plus secondary HSL. Done. Saved as a Preset, looks fine, and works with all other Scenes shot with that Lens...
But holy moly I can't get that corrected with Davinci Resolve 17 beta.
I am fairly new to Davinci, but anyways very very happy with the Performance on the huge 6.2K CinemaDNG folders the X7 (and X5s - 5K) create. Runs very smooth on a iMac Pro 10 Core off of Thunderbolt 3 RAIDs, and is a joy to color grade otherwise (except that Green Cast ND Filter footage I am too stupid to get done with).
Here's a DL link of 44 Frames of a CinemaDNG Sequence with that Cast in case one want's to have a look at that.

What is the approach here with Resolve?
Thanks for your help! Any Tipps highly appreciated.
Cheers
Christoph
