I'm trying to utilize the quirks of anamorphic on a project that wants to be tall. So we're choosing the flat ratio (1.85:1). I want to do as little cropping as possible. I think the best way would be to use a tall sensor like that on the Sony Venice, and shoot open gate with a 1.33x lens. If I'm right, that should get me desqueezed to about 1.99:1. I don't think I'd lose much of the images rolloff cropping to 1.85:1.
Is there a better way to do this? Anyone have advice?
