Dear Fellow Diver:
Even after years of waiting for this moment, and
  countless worldwide encounters with sharks (including
  some bad-ass ones), I wasn't wholly prepared for the
  first experience. An eight-foot oceanic whitetip shark,
  cruising perhaps 70 feet away, made a seamless left turn
  and headed directly for me. From my perspective, her massive
  pectorals and dorsal formed a near-perfect equilateral
  triangle; the resemblance to the business end of a
  World War II fighter was overwhelming. The featureless
  sapphire blue of our surroundings did nothing to reduce
  the effect. At the last second, she made an invisible
  course correction and passed within a foot of me. After a
  few seconds, my heart rate and breathing returned to normal
  ,and my brain re-engaged. Its first thought: "Oh my
  God, let's do that again."
 The shark and I were just 25 feet deep off Cat Island
  in the Bahamas. It's one of the better places to find
  these critters, though they exist in the deep waters of
  tropical oceans around the world. I was one of 11 divers
  on an oceanic whitetip photography trip with Big
  Fish Expeditions, the operating brand for underwater photographer
  and
  tour leader Andy
  Murch, who works
  out of Victoria,
  Canada. Andy,
  a 40-something,
  big-animal-hugging
  adventure junkie
  is easygoing and
  good company. He
  also has a story
  or two (ask him
  about being held
  at gunpoint).
  True to his
  branding, Andy takes divers to see and photograph big animals, with
  a particular emphasis on sharks. In fact, two of
  my fellow divers had just come from Tiger Beach,
  another Bahamian venue where they'd spent a week
  with Andy shooting lemon and tiger sharks. Which
  gets me to an important point: If you want to see
  pretty reefs and the usual tropical reef fish,
  this is not your cup of tea. The divers were
  there for one reason -- to get close to as many
  oceanic whitetips as possible, and get as many
  high-quality photos as they could. And sometimes
  that means suffering at the hands of fate and,
  well, human stupidity.

On my first day, I boarded the dive boat,
  chartered from Bahamian dive lord Stuart Cove, at
  the Hawk's Nest Marina, on the south end of Cat
  Island (which is shaped and oriented uncannily
  like Italy). The boat is 46 feet long and designed
  to hold up to 30 divers. It has plenty of shade cover and a perfectly adequate
  marine head. I wouldn't want to be on a 20-person charter on it, but for our
  group of a dozen diver/photographers, it was perfect. The crew, all Stuart Cove
  employees, came with the boat. They set up our gear for us, and then we left it
  on the boat for the week. We were responsible for washing it when the trip was
  over. The crew struck the perfect balance between doing for us and allowing us
  to handle things as we wished. There were no newbies on the trip, and we all had
  our idiosyncrasies.
 We took a 30-minute ride to an area where a group on a different tour had
  encountered three sharks the day before. Parked over a practically bottomless
  ocean, divemasters Charlotte and Beto prepared and deployed an unholy stew of
  chopped fish and menhaden oil. Within a few minutes, a clearly visible slick
  extended to the limits of our vision. Surely we'd see white-tipped rounded dorsals
  cutting through the water at any moment.

  cutting through the water at any moment.
This is where human stupidity comes in. According to the Wikipedia page
  about oceanic whitetips, they suffered a population reduction of 70 percent from
  1992 to 2000 in the area we were diving, thanks to long-lining and finning. So
  we waited. Nobody suggested we head the half-mile inshore to dive a reef. There
  wasn't even much whining. After a couple of hours without any success, the crew
  went to Plan B, which was to troll a baitfish and try to hook a tuna or mahimahi.
  The idea was that the fish struggling on a line would ring the dinner
  bell for the whitetips. Somewhat to my surprise, we managed to hook and play
  five mahi-mahi. Even more to my surprise, not a single shark arrived to take
  advantage of the captive fish. At 3 p.m., with nary a shark sighting (but some
  fresh mahi in the cooler), we headed back to the resort with dry wetsuits. If we
  couldn't dive with sharks, we weren't diving.
If you're going to get skunked on a day of diving, Hawk's Nest Lodge is a
  perfectly fine place to drown your sorrows in a $6 Kalik beer. All 10 rooms are
  clean, well maintained and have a view to the ocean. It's a 50-yard walk to the
  hammocks and a gazebo at the beach, a perfect place to read a book. Hawk's Nest
  is located away from everything, so it's not like you can walk into "town" for a
  beer or a meal. I could get a cab to somewhere, but what little there is on the
  island takes a 30-minute cab ride. The lodge has a dive shop at its marina, but
  I was self-contained with Stuart Cove so I didn't investigate it. The A/C in the
  rooms works well, as does the plumbing. What else would you want?
Well, I'd want Wi-Fi in the rooms. The only Wi-Fi access point is in the
  office, which is in a small separate building (there's an old Dell desktop for
  public use). I got the best signal either by sitting in the office (they were
  happy to have me there if they were open) or in the chairs out front. The problem
  was that I was exposed either to the sun or, in the evenings, a blitzkrieg of sand flies that left me looking like a chicken pox patient the first night.
  The lounge/dining-room combination was a tolerable compromise of safety from
  insects and a marginally adequate Wi-Fi signal.
The lodge itself is a large, airy room divided into a bar/TV area and a dining
  room. It looks like every other perfectly reasonable diving/fishing lodge
  I've ever visited in the tropics. There's a big-screen TV that was turned on way
  too much (the NBA playoffs were on, to be fair). Out the back is a patio and
  freshwater swimming pool, which give way to a short boardwalk down to the beach.
  All in all, a lovely place to spend downtime. Were I stuck there, I'd have been
  fine for two to three days until cabin fever set in.
 My package included all meals, and if I wasn't satisfied with what they
  were serving on a particular evening, I could get food a la carte (out of my
  own pocket, of course). Breakfast was borderline sumptuous, including eggs,
  bacon, pancakes (on some days), fresh fruit and toast, all served buffet
  style. They packed sandwiches and fruit for us to take on the boat (the last
  question I heard before the boat left the dock each morning was, "Do we have
  the lunches?").

Dinners were unfortunately hit and miss; they just brought us whatever was
  on our menu that day. It was always edible and sometimes good but never stellar.
  I realize that the resort is in the back end of never, so supplies are difficult
  to get and expensive. But a little creativity would have gone a long way. In
  particular, I felt bad for Andy, a vegetarian. The kitchen staff seemed clueless
  about how to feed him, except for they knew not to put a pork chop on his plate. Too often, his meal seemed to be our "meat/vegetable/starch" offering, less the
  meat. If you are a vegetarian, consider bringing some bags of beans and showing
  the kitchen staff how to prepare them.
Over a post-dinner Kalik in the lounge on the first night, I got to talking
  with a group of sport fishermen who were also staying there. They complained
  bitterly about losing hooked fish to sharks, even seeing the sharks snatch the
  fish just as they were about to boat them. Needless to say, my ears perked up,
  and I asked, "Where was this?"
So on day two, we headed to Columbus Point and started the chum/slick exercise
  again. It wasn't 15 minutes before the first whitetip showed up, cruising
  around the back of the boat to slurp up the fish bits Charlotte was tossing in.
  There was also a bait box suspended at 30 feet, which kept the sharks interested
  once they found us. When I got in the water, Beto was hanging near the bait
  box. He held up two fingers, then pointed to a second shark. I drifted down and
  just marinated in the blue infinity with two exquisite apex predators swimming
  around us.
Before the other divers get into the water, I should take a minute to talk
  about why you might choose to spend a week of your life (in my case, four days
  of two tanks each) just to be close to this one particular species. Suppose
  somebody said to you, "You can sit in among a herd of elephants or a streak of
  tigers (yes, that's the official term) for
  three hours each day for a week. If you were
  an elephant or tiger junkie, you'd probably
  drop everything to sign up. Oceanic whitetips
  date from the Jurassic period; they're perfect
  for what they do, and you know it the
  minute you get close to one. Their grace,
  cool and situational awareness is astonishing.
  And when you see sunlight dappling their
  back as they cruise at the surface, you wonder
  if any creature can be more perfectly
  designed, more beautiful.
 More divers entered the water, and more
  sharks appeared, as if to offer good shooting opportunities for all the photographers.
  Over the course of that
  dive, Beto eventually got up to five
  fingers -- all five animals were adult
  females ranging from six feet up to
  probably nine feet (one massive specimen
  I referred to as "Submarine"). The
  sharks were curious. I would describe it
  as a wary respect, along the lines of,
  "I don't know what you are, you don't
  give off 'wounded' vibes, you're about
  my size, and we didn't make it 150 million
  years as a species by randomly
  attacking things we didn't recognize."
  But they would pass very close to us,
  and clearly had a sense of which direction
  we were looking. I would routinely
  see a look (or a lens) from another
  diver, then turn around and see nothing
  but gray-green shark body passing in my
  field of vision.

  field of vision.
The only time the predator/prey balance shifted a bit was at the end of
  the dive. Without exception, once a diver surfaced and began swimming toward
  the boat, a couple of sharks would peel out of the diver/shark constellation
  and go see what the commotion was on the surface. For these open-ocean predators,
  commotion on the surface often means food (yes, they are the ones who have
  picked off countless shipwreck victims over the centuries). They'd pull right up
  behind me or shadow me directly below. If one got too close, a kick with a fin
  would always send it away for a minute. I began to think of it as a game called
  "Where's the Escort?" It wasn't a question of whether you had one; it was simply
  a matter of finding her. Every day afterward, we went to Columbus Point and never
  had fewer than five sharks on each of the two dives. Eight was more common, and
  I laughed the first time Beto had to flash 10 fingers and then two more to show
  we were surrounded by a full dozen oceanic whitetips.
During multiple dives, schools of rainbow runners would pass through or
  below us; whether they were attracted to the bait slick or just coincidentally
  in the area, I don't know. Then on one magic dive, a blue marlin came screaming
  into such a school, twisting left and right as he tried to snare one of the
  rainbow runners. All that action was a bit deeper than I wanted to chase, but I
  got a good view of the proceedings from above. A couple of divers plummeted down
  into the maelstrom and got good marlin shots. There were also brief sightings of
  a single sandbar and a single silky shark -- I saw neither. If you want to be
  sure of seeing silkies, there are better places to go.
While the trips are not photo seminars, and there's no formal instruction,
  Andy is a top-notch pro "shooter" and was always willing to share expertise or
  review shots for people. The group was full of serious amateur photographers, and
  we spent much of the down time on the boat discussing the minutiae of underwater
  photography. My group was mostly Americans, with a delightful quartet of Italian
  divers to add some garlic and oregano to the sauce. There were more than a few
  of us with gray hair -- you need to have found a deep passion in life to go on
  this trip. Most importantly, there wasn't a bozo diver in the bunch. There was
  the usual mix of personalities (some more enjoyable than others), but to a diver,
  they were supremely competent both in and out of the water.
If you're fresh out of certification camp, pass on this trip until you have
  at least 100 dives. It is very much every man (or woman - there were three in my
  group) for himself or herself. The divemaster is there to help, but with a cloud
  of a dozen diver/photographers around him (or her), you're mostly on your own if
  you have a gear problem. Furthermore, photographers are the epitome of solo divers
  -- they have no awareness of anything around them except whatever they're trying to shoot. An example: A photographer's tank slipped out of his BC and was
  happily floating there, held only by his regulator hoses. He didn't even notice
  until one of the two non-photographers in the bunch came over and reattached the
  tank (the divemaster had spotted the issue and was headed there too).
This is also not the trip for those who have buoyancy control issues. You
  are suspended, untethered and over a 1,000 feet of water, so if you drop it,
  it's gone). If you spend the entire dive trying to get your buoyancy right, at
  the least you won't enjoy the dive much, at the worst, you'll be in severe danger.
  And this diving is hard on your ears. The bait box is at 30 feet, and
  there's rarely a need to go below it. On the other hand, the sharks are often at
  the surface, so that's where you go to see them. This means a long dive (often
  90 minutes or more) where you're constantly moving between zero and 30 feet --
  pretty much the agony zone for most people's ears. I have tolerant Eustachian
  tubes, but my ears were gurgling for a week after the trip.
On the last day of diving, we tried a behavioral experiment. Hoping to
  attract more in-shore species, the boat began "towing" the sharks by driving
  slowly shoreward while keeping a constant supply of fish bits going into the
  water. We weren't sure if the whitetips would leave the comfort of the deep, but
  they followed us like puppy dogs, enabling the photographers to get some unusual
  (and perhaps incongruous) images of oceanic whitetips over reef bottom. Sadly,
  no reef sharks arrived to join the fun, but I lost count at 13 oceanic whitetips
  swimming around over the reef while photographers burned through terabytes of SD
  cards. It was a perfect finale to an awesome trip.
