Aren't you the colorist for that 5D Short film in Kenya?
If you're looking for DNGs you can download the 3 Gigs that I uploaded:
viewtopic.php?f=2&t=3791I'm definitely not a Cary Fukunaga but they're new DNGs and you can test things out. I don't see any color banding at all when pushing the material in Resolve 9's latest build, using BMD Film, but if you see some let me know where.
Oh, I will say that in some ProRes footage that I shot during my testing phase I DID see Banding under very specific circumstances, but I also think it was due to my retina display. On the Barco 2K in our DI suite I don't remember seeing the same banding.
And again, I definitely haven't seen any in RAW but let me know what you think.
