Improve my photo techniques. I want to add a 2X or 3X diopter and turn my 105 into an underwater microscope and take just rediculous macros. Taking half-a-rice kernel and filling the frame. That kind of stuff.
Nothing about my diving facinates me more than getting home and pouring over the life that is in a 3 or 4 square in patch around my subject. Its just amazing stuff.
The diving things I'm fine with. I can float, I can drop, I can get around without drooling on myself. I don't get lost, and I don't make a mess of the dive site. I can valve drill, I can kick, I can mask drill, I can basic 5, etc, etc... That's the important stuff, and all that I'm satisfied with.
The shooting thing I need lots of help with.
