Divers in a large school of sardines.
Shot in Panglao, Bohol, the Philippines.
Olympus e-pl5 in PT-EP10 housing, Olympus 9-18mm, AOI 4" dome port, two sea&sea YS-D1 strobes.
The strobes were fired because I wanted some shine on the school of fish, but I'm not sure it got me anything other than some extra backscatter at the range and power I was at 
I followed the 700px long side rule, but I feel it's a tad tiny. Full version available here if anyone is interested:
