I took this in the rain. It lightened up just enough for me to grab the camera again (with one of those plastic rain covers around the camera. Weird to handle the camera through that.
I took a couple of shots with my flash, which did reach him, but the pool water in between us and him caused nasty reflections. He also got a blue hue cast on him from the water. Decided to not deal with the flash. Went with my 55-200mm lens, since I wouldn't shoot at 2.8 because of the low light. I didn't want to risk it not being in focus, since the 2.8 is pretty narrow, even at 70mm. Would have shot at 5.6 - 8 anyway.
1/125, f/5.6, ISO6400, 200mm
