I was curious as to setting the ISO in camera. If I set it higher for night shots or for speed,what is the difference between that and adjusting the ISO in Photoshop or Nikon View6. I notice I can increase the iso in those programs. Will the settings on the camera allow for the shot to come out properly, or will the grain just be increased and let more light in.
