What is the point of Aperture priority and Shutter priority since they are just the inverse of each other?
I intentionally phrased the question title a bit provocatively. What I mean is this: Aperture priority mode (Av) means that I select an aperture, and the camera selects the corresponding shutter ...
So what's the benefit of using one over the other? The way I understand it, in Av or Tv, you only have to adjust the shutter or aperture, and the rest is done automatically for you...is this correct? ...
