Sadly, I'm not finding the 7D Magic Lantern raw workflow reliable and practical for my needs just yet. Some of it could be due to the card that I ordered. My colorist and Da Vinci Resolve expert CJ Adams and I managed to work out the workflow to a certain extent last night, but we were seeing odd things with the overall color cast of the image, and broken frames which is really unacceptable. Information is out there with regard to how to work through some of these issues, but I think a few more months of the Magic Lantern team hammering on it and working out some of the bumps in the workflow may be required before it's stable enough to depend on for a real shoot. I do plan to continue to play with it and see if there is a way to optimize it for later projects, but I'll probably not end up using it on this one.
In the interim, for some of the beauty shots and interviews where I want that really filmic dynamic range, I'll be renting a BMCC from Rule Camera in Boston. At $150 for a weekend rental, I think this is the most practical and reliable way to get the sort of look I'm after.
