So, first outing shooting underwater. Bought the rig at Backscatter, and promptly hopped in at Breakwater. Setup is a Sony NEX-6 with the 16-50mm kit lens, Nauticam housing with Nauticam flat port for the 16-50. No diopters or other adapters. Sea and Sea YS-01 strobe. Vis was absolute garbage down to 30' (see last pic), where it really opened up.
Dive #1 produced nothing good, which was a bummer because I saw a juvie wolf eel swimming around, which I'd never seen before. Biggest lesson learned - turn on the flash. All my pics were either totally black, or totally white after I turned the flash on and realized I had no idea what the settings meant. D'oh! I also had left the camera in fully automatic mode - figured that was best for my first try.
Note: In between dive #1 and #2, a body was pulled from the water. That was a real downer, but a good lesson for the beginner diver we were with to always use the buddy system.
Dive #2, started to get some pictures that I feel good about (because after dive #1 I was thinking I may have just wasted $3K.
So here they are, suggestions would be appreciated. Mean-spirited criticism will be met with snarky retorts.
