Camera Savvy, Marine Life Knowledge and Scuba Skills Combined

Story and photo by Marty Snyderman

I feel a sense of accomplishment when I think about what it took for me to create the photograph of the whip coral goby (aka wire coral goby) that accompanies this article. From a technical perspective, after finding the fish I took a light meter reading on the blue water in the background to determine my f-stop (aperture), adjusted the power of my strobes to match the intensity of the ambient light as affected by the light meter reading and my strobe-to-subject distance, composed the shot, focused and tripped the shutter.


In previous articles I have discussed in greater detail the step-by-step process involved in capturing a blue-water background as opposed to having the background water appear black. My fundamental point is that getting this image was not merely a matter of having a good grasp of the technical issues involved. Knowledge about marine life and basic diving skills were every bit as important.
I spent the first several years of my diving career unaware of the existence of whip coral gobies. After becoming aware of them I spent the next several years unable to find and photograph them. Whip coral gobies can be a challenge to find because they are low-profile and blend very well with the whip corals they live on. However, a few years ago a Malaysian divemaster taught me something. He said the trick to locating whip coral gobies is to look for an anomaly - some irregular shape - on the whip coral as you look up and down the length of the coral. Find a shape that isn't quite like the rest of the coral, and the odds are you will be looking at a whip coral goby.
The importance of having good diving skills came into play because I had to position myself very close to the whip coral to compose the image I wanted, and I had to avoid bumping into the whip coral and frightening the goby into hiding.

To get blue water in the background I positioned myself below the whip coral so I could shoot at a strong upward angle. I had to be careful not to ascend or drift into the whip coral so I positioned myself on its downcurrent side, achieved neutral buoyancy and composed my shot. Being able to hover in the water column and maintain my exact position so I could compose, focus and shoot required good buoyancy control and, without it, there would have been no chance for success.
All too often knowledge about the marine environment and mastering diving skills are not given as much credence as they should be when it comes to analyzing what is required to consistently create the great underwater photographs we all desire. The takeaway message: Now that you have been reminded of the importance of these factors, do what's necessary so you are prepared when opportunity knocks on your door.
