I went diving off Kume Island a couple of weeks ago. The water is still quite cold in February so I was wearing a hooded 5mm wetsuit, but the visibility was excellent and there were plenty of things to see.
A small whitetip reef shark (Triaenodon obesus) hiding in a cave. This was shot at 17mm, so I was only a couple of feet away. It’s quite emboldening having all the underwater camera and strobe equipment between you and your subject. Hope it recovered its night vision after being dazzled by 4 or 5 very bright flashes.
