Shot with 4 Canon 580 Flashes. Flash 1 directly above the fish tank with a Honl 1/4" grid and soft gel and lights the hand and splash. Flash 2 pointed at background used another 1/4" grid with a red gel creating the red spot. Flash 3 was behind (2 oclock), and above the water line at a 45 degree angle to the top of the water giving the red water surface. Flash 4 was off to the left and behind with an 1/8" grid and soft gel giving some light behind the hand. Drop, click, drop, click, repeat, repeat.
F11, 160th. Flashes set between 1/8th and 1/2 power depending on grid used and amount of light needed.
