Yeah, I use the auto ISO for general room shots without the flash and forgot to turn it off for the NightSea shots. I really wish I had, but I was in such a rush (we had already more than overstayed our welcome) that I totally spaced. I kept trying to control the exposure, slowing the shutter down and it kept trying to compensate by pushing the ISO. D'oh. I REALLY need to get back there when I can take the time to focus on taking pictures because he has some corals that really look AMAZING with the NightSea.
