Straight after diving yesterday we were offloaded onto the Solitude, an old Japanese research vessel now beautifully restored as a live aboard dive boat. There are more crew than divers with a large and spacious dive deck and camera room .
First dive of the day was the wreck of the Iro, a WWII Japanese vessel sunk in 1944. It is incredibly encrusted with masses of hard corals, more than I have seen on a wreck before. I shot quite a lot of available light images instead of strobe as the Nikon D4 is an extremely capable camera for this sort of photography, even though it was quite deep and dark at 16 meters.
We then dived Chandelier Caves which I have never seen before, and found very challenging photographically. It is very dark with stalactites hanging down into the water. For some inexplicable reason I forgot everything I have known for years about shooting underwater in low light conditions, and I struggled because of it. Of course I remembered it all when I got back onto the skiff after 90 minutes of blatting about to little avail.
