Typically, when I get to a dive site that I have not been to before, my initial thought is to use my wide angle lens so I can try to take pictures of the large reef structures and any fish aggregations so that I will have a general sense of what a particular dive site is like. Most of the time I dive with groups, so if I am shooting wide angle the challenge is to only have one or perhaps two divers in the image. I usually do alright at keeping up with the group, although by buddy says I am pretty slow and tend to be at the back of the group.
Nevertheless, there are times when I pull out the macro lens to take underwater pictures. A trip we took to Curacao not to long ago was one trip were I was glad I had packed the macro lens. We dove with Ocean Encounters, which is an excellent shop. Good safety briefings, skilled and well trained staff and solid equipment. One of the dive leaders we dove with on several dives was Pol Bosh. Pol is extraordinary at finding the small critters that live on the reef system in Curacao. Curacao has quite a few sea hares which are shell-less mollusks. One such sea hare he found was a Petalifera Romosa. This Petalifera Romosa was perhaps at most an inch in length, yet with a macro lens it looks fairly large. This sea hare dwarfed some of the other sea hares that Pol found and were at most only about a quarter of an inch or a centimeter in length. (I wish my eyes were that sharp and could readily spot creatures that small).
Pol was also quite skilled at finding arrow crabs.
Curacao does have a multitude of macro subjects. So typically I was way at the back of the group with my buddy trying to hurry me along.
I hope we get to go back to Curacao to get lost in the small small world of creatures that live off of its shores.
