Thanks. I honestly have no idea how they came out so well. The shutter speed was pretty slow since there wasn't enough light to go any faster. Halides may look bright to the eyes, but they aren't even close to sunlight's intensity. I'm surprised at the clarity myself. I purposesly shot the hogfish when it was relatively stationary, but I fully was expecting some motion blur. It helps a lot that I was shooting with a dSLR which doesn't have much shutter lag.
