I'm new here and I know almost nothing about underwater photography. Today I've been trying to trigger a flash that was outside of the water (not really far from the transmitter, 3 metres maybe) but it didn't work. I've used cactus v4 radio triggers, do you know if there is any other system I could use to fire a flash that is outside the water? thank you very much :) Nico6/17/2013 7:34:03 AM
