I am having fun with my new Canon 6D. I was out at the wetlands the other night at sunset. It was getting pretty dark, but there was a beautiful black-crowned night heron, waiting to be photographed. I had the 100-400 lens on, and was in the car and hand-holding the camera in the growing dusk. An impossible photo, but what the heck - it's digital, and costs nothing to try, right?
Automatic ISO - 10,000! Not a sharp photo for enlarging, but pretty amazing....
ISO 10,000. If we had heard that on Star Trek in the 60s, we would have thought it was ridiculous. Of course, it would have been ASA back then, anyway. High ISO can mean the difference between getting a shot and not getting it.
