Just because the latest single-sensor digital camcorders allow you to shoot with available light does not mean you should shoot with available light. However, the importance of being able to should not be overstated. To that end, John Brawley put together a great practical test utilizing six different cameras in the same setting, in order to evaluate which format would work best for a forthcoming feature to be shot mostly on Parisian streets at night. The cameras/formats were Aaton 35mm, Aaton Super 16mm, ARRI ALEXA, RED ONE MX, Canon 1D Mark IV DSLR, and the Sony F3. Here’s the video of the test, which is refreshingly devoid of test charts and instead focuses on the devices as storytelling instruments: More »

Now, as part of the Technicolor CineStyle picture setting release, the user manual mentions that one should shoot at “multiples of 160.” I assume Technicolor knows what they’re talking about, but the question remains.
