These real world camera values…and definitions do have limits.…However, the vray physical camera, although it's based on…a real world camera, does not have limits,…but otherwise works the same.…Let's talk about the relationship between two values here.…The shutter speed at the top, the F-number at the bottom.…In this example, we're using the same exposure…for all of these settings.…We look over here at the far right,…
