Hi all!

I'm preparing to shoot a short movie and it's gonna be filmed using the 7D, HPX171 and maybe 5D. Wright now I'm preparing to test how the camera and DSLRs hold up when cut together. I wanna do a dynamic range test comparing this cameras.

I'm just looking for some advice on how to approach at this. I've never done a dynamic range test before so some basic pointers would also be much appreciated!:) Where do I get started?? :)

Thanks!
