I'm a director, but most of the times I will also be the dop on my films. When I am not, though, I have the chance to work with other great dops and learn a lot with them and their methods.
I've recently shot a commercial with a ASC dop and other with a ABC dop, and they both did change the ISO a lot during the same film. When asked why, the answer was simply that this way they would change the dynamic range according to the scene.
Even though that makes sense, I have always been doing the same just changing the exposure and balancing my fill lights, usually working with ISO 800 during the whole process.
I was wondering how do you guys approach that, and why.
