This shot captures a lot of what scuba diving means for me - the sense of mystery and exploration, the alien landscapes (seascapes?) of coral reefs, and most of all, the fact that scuba diving is like flying - the closest we'll ever get to three-dimensionally free moving flying.
Though I've been scuba-diving since 2006, I've only recently got a proper underwater photography kit. Most of the photos I took on this dive trip to Pulau Aur were what I'd call "procedural" - the equivalent of tourist snapshots, albeit at depth. This is the only "art" shot I made on the whole trip, and even so it was a case of neccessity - the flash on my camera had limited range, and the whole photo came out too blue.
