A shutter speed of 1/400 of a second (aperture = f2.8) was certainly fast enough to freeze any coral movement, but it was at the cost of depth of field. The depth of field is very narrow. It was a good choice, however, because the narrow depth of field focuses the eye on the sharp part of the coral in front.
