ISO 400 -- pretty fast, but why is the iron ring more in focus than the critter? What other camera setting could have made both the iron ring and the rat in clear focus?
Paul, the rat is slightly blurred because of the slow shutter speed (one fiftieth of a second). ISO 400 because there wasn't much light in the shade under the roof. If I'd increased the ISO to 800, the speed would have been 1/100, but I suspect even that wouldn't have been enough to get the rat completely sharp. ISO 1600 (and therefore 1/200) would have done the trick, but in retrospect, I'd have been inclined to go the other way and drop the ISO to 200 to make the motion blur more pronounced. Whether I could have held the 300 mm steady enough at 1/25, even with image stabilisation, would have been the question, though.

ReplyDeleteGreat moment captured, though.
