I wasn’t blown away by the look of Zodiac, but I wasn’t down on it either. It sounds like what really attracts David Fincher to the Viper camera is the workflow:
David loves the workflow of the Viper. He likes seeing what he gets. He asked me once, “Don’t you sleep better knowing it’s all good, all in the can, with no scratches?” I’m looking at the answer print and I’m happy with what I see. He also raved about how much time they saved on reloads on Zodiac.
