Depth of field, lighting and shutter. I started with 16mm and have shot 35mm as well. So I light like film when I am looking for that look. Now that I have access to RED and have a 35mm lens adapter for my 1/4 chip video camera, I pays to light like film because of the depth of focus. We are creating motion pictures either with film or digital.
Now shutter angle is a different matter. I did not like the shutter angle on "Public Enenies". WAY too much motion blur. I prefer film motion blur which can be done on a digital cinema camera. I use motion blur for effects but not story telling.
