A unique dive site off the coast of Yonaguni has been intriguing both archeologists and divers.  It is located on a remote island west of Naha (Okinawa's Capital), Japan.  It is known for schools of hammerhead sharks, but especially for the mysterious underwater formation that has long been a subject of debate. Is this massive linear rock formation a natural geological feature or an ancient city that is now underwater?

Macro photography has always been my first love for shooting underwater. Taking time to find just the right subject can force me to slow down and enjoy the dive, explore a little more and concentrate on just one thing: making an image. Once that special subject is found, the next task is to photograph it in just the right manner. For this there could be a myriad of options depending on my camera set up. As an SLR shooter, I prefer to use my Nikkor 105mm macro lens on almost every macro dive.

I felt guilty once as the only guest out of eighteen on a 12 day liveaboard who wanted to go on a night dive one evening. The dive guide said, “Let’s go!” and after that 90-minute one-on-one experience, I became hooked on night dives. It seems tough to beat the day dives on such trips, but night dives are an opportunity to do some serious critter hunting without a lot of effort. Simply put, things come out at night.

Nudibranchs are one of the most popular subjects for underwater photographers.  They are very colorful and usually stay still or move very slowly, making them easier to shoot than fast-moving macro subjects.  Photographers aim to shoot their rhinopores, little antenas sticking out from their heads, which substitute nicely for eyes (since nudibranchs don't have developed eyes).
