Develop diving skills. “For photography the most important skill is buoyancy control — the ability to hold yourself in a stable position in the water,” Snyder says. Most underwater photography is close-up work, and adjusting focus may mean moving the camera back and forth by fractions of an inch — while staying motionless in the water.
Predetermine lighting setups. While sometimes you may have a cooperative subject that will stay still long enough for you to adjust lights, sometimes you won’t. Snyder will find an underwater area similar to the one he wants to shoot at, and set up his lights there.
