Roberto just finished shooting Bond 22. He was gracious enough to allow me to post his comments from another forum.
"When I was doing tests for the last film, which I ended up shooting 3-perf Arri, I shot comparison tests between film and Red camera ( build as of October '07) digital. I was trying to emulate the film look with the Red as much as possible, so far as having several post facilities go through to a DI film out and project the results A/B. The reason was to prove to the producers that you could shoot part film, part Red, and seamlessly intercut the two. When done properly in the color timing stage, it was highly successful. The Red was able to be timed to match the 5219 without any problem except for scenes with extremely high overexposure and contrast.
I had the film timed first the way that I wanted it, and then asked the color timers to match it as best as possible from the Red data. The Red did superbly, and in fact when I shot night available light it did even better when I rated it at 2000 ASA. The noise was minimal and had great dynamic range.
I know that if I wanted to I could have "rigged" the results and made the Red footage look better ( different). It is such an open playing field that test results from various sources are really open to so much interpretation."
