My business partner and I have a bit of a debate, and we really want to learn from it. Our question is:
"Does the ISO affect depth of field?"
That is to say, does manipulating the ISO when shooting RAW R3D on a Scarlet GIVE YOU MORE LATTITUDE to to then change your F-stop to affect depth of field? Or does it matter what the ISO setting is?
I know setting the f/stop to a more open setting allows for narrower DOF, but since you can manipulate the ISO while shooting OR in post, doesn't it make sense the ISO does NOT influence how open or closed the aperture is (therefore influencing the DOF)?
ISO does not have to be changed at the shoot to create a different DOF, right?
