In this video we get a more in-depth look at how we actually go about color grading our Blackmagic Cinema Camera footage in Adobe Camera Raw.
*Special note about luminance adjustments: Surprisingly enough, I had a difficult time trying replicate the initial noise problems I experienced when I was first working on our BMCC footage. So between that and video web compression, you may not get the full effect of what I experienced. The bottom line is just to be wary of getting too aggressive with those particular adjustments. My working theory (based on nothing more than a guess) is that by "congealing" micro-level noise, the luminance adjustment can actually create macro-level noise that didn't previously exist and is really only apparent when the clip is played in realtime (which means you won't notice when grading just a single frame). If you have a better guess - especially if you've experienced this issue yourself - let us know in the comments.
Another cautionary note that I forgot to mention in the video - don't use Auto White Balance in ACR! It works just like auto WB would work in camera and it will change your white balance in the middle of the clip if the lighting temperature changes enough to warrant doing so. That definitely falls into the "stupid little mistake" category and it will cost you a re-render. Or, if you're like me, it will cost you several re-renders as you maddeningly try to figure out why the color is changing in the middle of a graded clip.
All of that aside, hopefully this video gives you a good idea as to how simple it can be to extract all of the potential that is available from the Blackmagic's 12-bit Cinema DNGs by using Adobe Camera Raw. Grades can be pushed incredibly far and the dynamic range (note the workbench shot in particular) is truly game changing if you're like us and coming from DSLR-based production. The implications for what this now-affordable technology will allow small production companies and indie filmmakers to achieve are staggering. And I think the clarity and flexibility of 2.5K RAW (and soon, 4K RAW) will tempt many more photographers like myself to venture into video production and bring with them new (and maybe unconventional) perspectives on how to light, shoot, edit, and color.
