hey guys. I'm kinda new to DSLR filming really, but since I plan on shooting lots of concert footage and in general low light videos, I have a small question. Is there any way to achieve nice low light with deep Depth-of-Field? Of course, to have deep DOF it is necessary to increase the F-Stop, but that will take most of the light present in the shot and relatively ruin it. Increasing ISO obviously helps, but I wonder, what is the best way to work on this? Especially for concerts, where it is not easy at all, especially if you're not on stage with the band but in the crowd, to keep moving the focus ring. What do you suggest? Should I just see what I'm working with every time and decide what is the best option? Just try some stuff out before filming the real thing in every different situation?
