I am shooting an indoor short for a horror film with a Canon 60D; i am using one light source. I only want parts of the frame to be lit and the rest to be crushed out. To do this however I need to shoot at 1000 ISO. Tests look good on the laptop but I am wondering if the grain(which I like and want) will cause issues if I either down grade from 1080*24 or if I transfer it to any other format - broadcast. Or does it makes sense to shoot at 500 ISO at smaller aperture - I will still get some grain but also greater DOF and a DSLR image which is not as appealing.
