A diver's got to know their limitations: Diving within your limits.

Ask any experienced photographer or videographer and they will tell you that they often hold their breath for a few moments to get the shot. Scalloped Hammerheads are notoriously shy and afraid of a diver's exhalation bubbles. The trick to filming them is either to be on a closed circuit rebreather or hold your breathe as long as you can to let them come closer to you before you must take another breath. Of course, we are trained to never hold one's breath upon ascension but to get the footage down deep, it is pretty common.

Sorry sharky! I did not hold my breath out at Malpelo & Galapagos and ended up with relatively good shots (I was on OC) vs. the Mk6 guys. I find that long steady rythmic breathing (1 in 1 out >15m else 2 in 2 out) works better around predators in most cases. Works great in Asia too! Perhaps understanding a little of these magnificent creatures' behaviours helps a lot too!
