The last difficulty with photography is movement. The water is moving, you are moving, the fish are moving. How on earth can you get a photograph that is worth anything if EVERYTHING is moving? Persistence.
I’m sure the longer you do it the easier it gets. The simplest things such as breathing can cause you to move up and down a foot or two. Inhale, rise. Exhale, drop. And you really shouldn’t hold your breath underwater, lest you get a lung injury, which can happen with as little as two feet of ascent while holding your breath, depending on your depth. Having had a pulmonary embolism once in my life, I wasn’t keen on another lung injury. But the overwhelming urge to hang still found me trying to hold my breath just to get that illusive photo. It’s more difficult closer to the surface where neutral buoyancy is a little more difficult and the surge is greater. Not to mention that the fish don’t really like to pose, although admittedly there are some who don’t shy away as easily as others.
The male Stoplight Parrot Fish is one that just does not stop swimming. He is really hard to get a photo of, and I followed him for 15 minutes or so, and snapped about as many photos.
The angel fish is equally illusive. He never stops swimming, and rarely swam in my direction.
These little guys tended to be curious, and head-on shots were a little easier with them.
Then there are the Sand Divers who lay on the bottom and blend in, hoping not to be seen. Photo courtesy of DH, as mine did not come out well.
These little guys are about an inch long, and cover the bright orange coral. I found them difficult to photograph because of their size and movement of the surge while using macro required tweaking of shutter speed and f stop.
This last guy is less than an inch in length, so I think the fact that I got him was probably nothing more than dumb luck.
