While photographing a freediving trip for Riffe International to the island of San Salvador in the Bahamas, we had a unique weather window that opened up good diving conditions to a very exposed point on the southern side of the island.
This point is unique in that it has a large, deep sand bar that lies in about 45-60ft of water but then plunges into extremely deep water just beyond the sand's edge, which made for the alien look of this particular image.
We had been diving hard all day but when the sun broke through the clouds I convinced Alli to jump back in with me to see if we could capture something special. Alli is an extremely graceful diver and as the sun broke through the clouds, she glided effortlessly above the sandbank and I was able to capture the moment.
Due to the strenuous nature of freediving photography I use a mirrorless Sony Nex-7 camera system with a fisheye adapter because its small size means a much reduced drag profile and therefore less effort to swim it up and down through the water column while holding my breath.
It's not uncommon for me to make in excess of 50 dives to deeper than 60ft during the course of a day, so the drag reduction is critical to my ability to photograph these amazing athletes.
