A Few Words From Mike.

No. 5
"Pinnacles" - Ponta D' Ouro Mozambique, Africa
     A few short years after I abandoned the grind of my office job in New York City, I was in the need for some adventure. I just finished up working as a mate on a dive vessel in Hatteras, North Carolina in 1999 and was in the market for a new job as well. Scanning the internet one day I came across this dive job posting: 
"Dive resort manager wanted for remote African dive camp in Mozambique." 
     "Perfect", I thought to myself. "Where is Mozambique?" "What is a dive camp?" What better place to run off to than a country I had little idea where it was. I did know it was in Africa, but I didn't know where. After doing some more research, I discovered that Mozambique was located on the south east coast bordering South Africa, Zimbabwe, Zambia, Malawi and Tanzania with coast line twice as long as California on the Indian Ocean. I wanted to experience life outside the United States and living and working in Mozambique might be just what I was looking for.

     I spoke to the dive operation manager of the dive company, Blu International, over the phone, who was based out of Johannesburg, South Africa. We both decided the job would be perfect for me. He indicated I would be sleeping in a tent and getting paid 2000 South African Rand per month to manage the dive camp on the very southern tip of Mozambique in the small town of Ponta D'Ouro; a popular dive vacation destination for South Africans. That didn't sound so bad. Even though 2000R was equivalent to a mere 333USD, we worked out the details and it was a deal. This job wasn't about the money, but the adventure.

Poles and reeds were the primary materials used in
most of the structures in Ponta. 
     After an arduous flight and cross country drive for ten hours (a story that needs to be told another time), I arrived in the small town of Ponta D' Ouro. To call it a town could be considered an over statement. Most of the buildings were gutted, falling down and riddled with bullet holes left over from a harrowing civil war that only ended a few years prior. (This too, is a story for another time).


     Most of the newer structures were made with reeds and framed out by tree poles. There were a handful of proper private homes in the area, but they were mostly owned by foreigners from SA and Portugal, the European country that colonized Mozambique prior to 1975 before it reached independence. 

My home for six months...a leaky tent.

    After getting settled in to my humble abode (a leaky tent), I wandered down to the beach to get a glimpse of the Indian Ocean for the first time and to see how the diving was conducted. As I walked down the beach, all I could see for miles was vacant waterfront property over looking the blue sub-tropical waters.  Ponta D, Ouro, when translated from Portuguese to English means, 'point of gold'. It was 'golden' indeed. 


      It was towards the point, where the town got it's name from, that I discovered where the dive operators set up and launched the dive boats. From a distance, I could see a semi-rigid inflatable rib weaving through the surf and heading in to the beach at full speed. I wondered when the skipper was going to slow down, but it became quickly apparent that he had no intention. With dive passengers holding on to straps and seated on the pontoons, the skipper drove the rib 20 feet right up on to the dry beach at full speed. The twin 150 HP outboard engines roared as the free spinning props popped up out of the water. I had never seen anything like.

     For the next 6 months Ponta D, Ouro was to be my home. I managed the dive operation and coordinated all my customers needs from accommodation to diving. It was a challenging job due to the remote nature of the camps. Everything had to be shipped in from near by South Africa; fuel, food and of course the tourists.

    I experienced some amazing diving over the next 6 months on the reefs of the Indian Ocean. However, the dive that stands out to be the most memorable was called, "Pinnacles".  About 4 miles off the beach was a couple of sea mounts that shot up from the sea bed that attracted a myriad of marine life. Schools of giant trevally and big eye jacks were common site as were zambezi and hammerhead sharks.

    (Unfortunately, my trip to Mozambique was before I became a keen underwater photographer, so I have no underwater video or photos to share with you.)

     The dive to Pinnacles that was the most memorable for me was done with a group of divers visiting from England. They had travelled a long way and were eager for top notch diving.  Sad to say their trip so far was riddled with problems. The tents that they were using leaked terribly and it seemed to rain nearly every night they were there.

The broken down vehicle left to me to help run the
dive operation. It never did run. 
     In an effort to make their stay more enjoyable, I promised I would take them to Pinnacles every day, since it was renown for being the best dive site, but it happens to be the furthest one from the beach and trips out there are sporadic at best due to the cost of fuel required to get there. At this stage, preventing a dozen angry Brits from assaulting me was more important than a few dollars of petrol.

     The boat we used was about 21 feet in length with a rack running down the center line of the boat to hold tanks and BC's. Launching from the beach in Ponta D' Ouro is a team event requiring everyone to participate. 4 x 4's would tow the boat down to the water line where muscle power would finish the job. Paying divers would line up along the side and help push the boat down the beach and in to the surf. The skipper would say, "one, two, three", and on three everyone would push. Once the boat was in the water all of us would hold on to stabilize it. On a calm day this was easily done, but when 3-4 foot waves rolled in holding on to that boat was a challenge even with 12 divers.

     The captain would enter the boat from the transom and head to the helm that was mounted almost up on the bow. He would lower the engine, start them up and then tell everyone to get in. Sometimes he would have to engage the props while divers were still hanging on with feet dragging in the water in order to prevent the boat from getting thrown back on to the beach again. This was a 'hairy' experience when it happened and not just for the poor person being dragged around.

An enormous GT or giant trevally, much like those seen at Pinnacles
on display by locals and the man who caught it who is in the bottom front.
    When the skipper gave the ok, everyone would pull themselves in to the rib over the pontoons. Some with weaker upper body strength would have to be pulled in by their britches. Once all on board the skipper throttled up and headed out to seas weaving in and out of the breakers. On many occasions these boats were known to flip over when captains would poorly judge when a swell was about to crest. Fortunately, I did not see this while in Mozambique, but I had heard many stories. 

    The trip across the open ocean was most often a bouncy one. These high speed boats were driven hard by there skippers sometimes with little consideration for passenger comfort, but then again this was Africa. Toughing it out with little complaint was a way of life there.

    Once at the dive sight, the skipper would triangulate positions on land to determine if he was on the right spot or not. The use of electronics was not the norm here and frowned upon by the veterans who prided themselves on being able to drop divers without there use. When everyone was kitted up and ready to go we all did a backward roll entry in to the warm Mozambique water and headed straight for the bottom 110 feet down.

    This dive was pretty simple. Start deep, drift through the water and look for marine life. After the first few minutes while cruising along the bottom we all spotted what looked like a very large zambezi shark, otherwise known as bull shark. This 8-10 footer swam around us a bit and then swam off. At first I didn't think much about it, but it bugged me as to the species of this shark. It didn't figure. It wasn't until after the dive later on that we all concluded it was a small great white shark that casually swam past us. Very cool.

     After a few minutes we left the bottom and began our very slow ascent to the surface  and spent the rest of our dive drifting with the current.  It didn't take long before someone was waving there hands and pointing out in to the blue water. There they were. A school of about 20 hammerhead sharks about 30-40 feet out from us. They would swim around in small circles together for a few moments and then disappear only to emerge again a few moments later. It was an awesome sight. 

    While this was going on some of the largest giant trevally I have ever seen would cruise up to us for a close inspection. Then off in the distance I could see yet another shark species on the fringe of our vision. As it drew closer in I could see that it was a zambezi. This shark would keep his distance and travel along with us for the duration of the dive.

    The show kept getting better. After only another minute a dozen beautiful devil rays in formation appeared below us. Devil rays are much like their relatives, the manta ray, but much smaller in size and are known to swim together in large groups. There we were drifting along in the wide open Indian Ocean with a dozen hammerhead sharks ahead of us, a zambezi lurking around behind us and these stunning devil rays cruising beneath us. It was breathtaking.

     This dive continued on for another 30 minutes until most of us started to run out of air. No one wanted it to end and popped there heads up only when the last breath had been drawn. One by one the divers scurried over the pontoons and back on to the boat. Just before it was my turn to hop in, I took one last look out in to the blue and saw, for a brief moment, a 6 foot marlin swim by. I just shook my head and knew this dive was going down in my log book as one of my all time greatest. Twelve years and several thousand dives later, my Mozambican drift dive is still in my top ten.


Afterword
So much could be said about the country of Mozambique and its people, but their story is one that requires respect and in-depth attention to tell. The country was emerging from a harrowing civil war when I arrived in 1999. What I saw was both inspiring and heart breaking. The people of Mozambique have come a long way, but with a long road still ahead.

Photo Tip of the Week
Ambient Light Exposures

     Although strobe lighting is critical for achieving well exposed images underwater, there are circumstances where you should shut them off and experiment with just the ambient light available. When should you shut your strobes? Here are a few tips:


1 - Most strobes are only effective with lighting up the foreground of your image within several feet to maybe 12 feet away depending on the strength of your strobe units. If your subject happens to be out of range of the strength of your strobe, then it is pointless to keep them on. Shut them off and try shooting ambient.  All the strobe will do is illuminate suspended particles in the water and create complications. It is important to understand just how powerful your strobes are by spending time out testing them on a subject at different strengths and distances with varying exposure settings.


The Fumitzuki destroyer from Truk Lagoon, was too
far away for strobes to be effective.
2 - Sometimes there is nothing in the foreground of your image that requires the use of artificial light. The subject may be drab, lacking color and generally not an important element to the overall shot.

3 - Maybe your camera set up doesn't even have strobes on it. Understand the limitations of your gear and seek subject matter where ambient light exposures would work well. ie, colorful reef systems may not work well, but wide angle shipwreck shots would.

ambient light and little foreground to
light up. Fujikawa Maru 2006©.
Experiment and try different situations and over time you will begin to see what works and what doesn't.

Good luck!

Just a Few Words First
      My top Top 10 Dives of all time countdown continues in this weeks blog. At number 6, I have chosen a specific dive from one of my trips to the Micronesian island nation of Palau in 2003. The dive was German Channel. Famed photographer, Doug Sloss has helped out this week and contributed some of his wonderful images to the blog. Thanks Doug! Scroll down and find out why this dive stands out.
     Beneath the Sea Dive Expo in New Jersey is days away and I have a busy weekend ahead of me with presentations and a workshop. Visit my the events section on my Facebook page, Evolution Underwater Imaging (by Mike Gerken) for a complete schedule.
     Olympus Dive Center has been reporting unbelievable dive conditions already this year. Last week they had 62 degree water temps and 50 foot of visibility on the inshore wrecks in 60 feet of water. That is impressive indeed. Pretty soon, the vessel I captain out of Olympus, the Midnight Express will be running and I will have first hand accounts of the conditions and excitement from North Carolina. Stay tuned!

     Shooting black and white images is the Photo Tip of the Week. Scroll down to the bottom and learn when you should shoot in black and white and the effects you will obtain by doing so. 

Happy diving!

No. 6
German Channel - Palau
     I would be remiss if I did not select at least one dive, out of many, from my excursions to Palau. The one dive that stands out above the rest was my dive on German Channel.

     In 2003, I had been vacationing from Truk Lagoon on board the liveaboard dive vessel, Palau Aggressor that was, at the time, captained by my close friend, Ryan Tennant. Unfortunately, this dive trip was before I began shooting underwater photography so I do not have any of my own photos to share. However, my friend Doug Sloss, who was also working on the boat alongside his future wife, Lorenza Sloss was kind enough to donate some of his amazing images for this blog issue. Thanks a million Doug!

     I should point out first, my dive on German Channel wasn't actually on SCUBA. At the time, I was an avid free-diver or breath hold diver and I decided that I would opt for my long fins, mask and snorkel over a cumbersome dive tank. Since the max depth was only around 60-80 feet, making short trips to the bottom on a single breath of air was possible. Lucky for me though, some of the best action on this dive was near the surface anyway.

     Many who enjoy the sport of free-diving will tell you that the feeling of being underwater without the use of modern technology is liberating and peaceful. It is also beneficial to getting closer to marine life that otherwise would be skittish around scuba divers and their noisy open circuit regulators.

     German Channel was a man made channel and is the only one in Palau that funnels incoming and outgoing tides from the inner lagoon. It is probable that this flushing action of the lagoon and the stiff currents that are prevalent here is the cause for the plethora of marine life such as manta rays, sharks, turtles and numerous tropical fish species.

     Before our group was to set out from the mother ship on board the skiff, we were thoroughly briefed on the dive by Captain Ryan. He indicated that our main objective was to see manta rays at the feeding station inside the channel and under no circumstances were we to touch the manta's.

     My plan was to simply snorkel on the surface while watching the divers below and to make as many short breath hold dives to the bottom as I could. I have little recollection of where we were during this dive, since I was merely content on following the group. During the first half of the dive we were inundated with large schools of scad, jacks, grunts, groupers, a sea turtle or two and a handful of sharks circling about the perimeter inspecting the action.

     It was very late in the afternoon and by this time of the day the water within German Channel becomes thick with plankton and algae. It was this nutrient rich water that brought so many fish in to such a small area. We watched the fish open and close their mouths filtering the tiny morsels through their gills continuously.  It was quite a spectacle.

     After maybe 20 or 30 minutes I could see Ryan point excitedly ahead of him deep below me as I lay on the surface resting. I strained my eyes to make out what he was pointing to. Off in the distance I could make out a large black and white winged shape creature dodging in and out of the hazy water. Manta Rays! It had to be. 

     I closed my eyes for a few seconds, took a few long deep breaths and dipped below the water. With long steady fin kicks I began my descent down to get a closer look. As I made it past the forty foot mark I could now clearly make out a manta ray about 30 feet away from me.  Getting excited while breath hold diving is a major no-no. Any adrenaline released in to the body merely uses up the precious supply of oxygen within your lungs. I had to keep my cool while observing these stunning, graceful and beautiful creatures.

Channel including these Black Tips. Palau, Micronesia.

     After maybe 90 seconds it was time to head back up to the surface for another breath of air. With long dolphin kicks it took only a moment or two before my head broke the surface. Once again, trying not to become excited, I rested and took long deep slow breaths. After three cycles of breathing I took one last deep breath and slid back down to where the manta was. As I got closer, I could now make out three mantas performing barrel rolls with their mouths agape feeding on the tiny crustaceans. 

     I have seen Manta Rays before, but it makes no difference. Every time you see them, it is a thrill like few other encounters in the ocean. After a another minute, I had to head back to the surface once again through the numerous streams of bubbles venting from the excited divers below. 

    Once back to the surface, I now had a birds eye view of all the action going on below me and to add more icing to this already sugary desert, more manta's arrived for their afternoon feed and were now closer to the surface where the lion share of the plankton were accumulated.  I lay there on the surface, relaxing and enjoying the show happening all around me.  It was like having front row seats right behind first base at Yankee stadium. 


     Pretty soon the manta rays were coming within only a few feet of me performing front rolls, back flips, barrel rolls and many other moves that would make any ballerina envious. It was an awe inspiring event to witness.  The other divers seeing what was going on above them slowly made their way to the shallows to partake in the manta show.

     It was about this point where one of the manta rays swam on a direct course right for me! While holding my breath at about 15 feet, all I could do was hope this enormous fish would veer off. The manta swam up, stopped and stared right at me only two feet away! A moment later, he turned off and bumped right in to me. I then looked at Ryan and shrugged my shoulders in a show of protest. "It was not my fault", said my facial expression and body language. "I did not break the rule. The Manta touched me!", I protested like a spoiled child.  I'm not sure if this argument would have held up in court, but I only received a single sneer from the captain and that was all. Nothing more came of it. 

     After a few more minutes the 5 or 6 manta rays that had performed their ballet act, now disappeared off in to the fading light in the bluish green water. The divers began to ascend to the surface and await the skiff to pick them up. I floated there feeling very satisfied and watched the setting sun.  The rays reflected an intense menagerie of red and orange light off the surface. This surreal sunset was a most fitting way to end what was, for myself, a top diving experience. I didn't know how the other divers felt, but I think I had a pretty good idea based on the beamy smiles emanating from below their masks.

In many regions of the world, manta rays are being hunted at alarming numbers and in many cases for the use of there gill rakers only! It is falsely claimed that they are useful as herbal remedies in asian medicine, but there is no basis for this.

Photo Tip of the Week
Shooting Black White

    First off, let me clarify one thing.  One should never shoot an image in the black and white mode on their cameras.  Shoot in color and convert to black and white later in post processing instead. By shooting in color you are creating more data in the image that when converted to B & W will yield more dynamic range or in other words, a larger palette of gray tones from shadows to highlights. You will also find more latitude in processing your image when shooting in color and the ability to add greater contrast. Lots of contrast is most often a desirable result when converting to B & W. Some would say it adds dramatic effect or to put it simply, it just looks better.

   When should one shoot in B &W? This decision is subjective and in the eye of the beholder. Some people love black and white photography, while others do not. Convert an image to B & W and hold side by side with its color version and see how you feel about it. I show many of people both versions of an image and most often the opinions are split down the middle as too which one they prefer.

    Generally speaking though, I would recommend converting to B & W under these circumstances:

1) When you want to achieve an alternate mood in your photo such as one of boldness, antiquity, or mystery to name a few.


Which one do you prefer?
The engine room of the Fujikawa Maru, Truk Lagoon©
2) When the underwater scene is green or having a lot of suspended particulates. Rather than create a blue image where there was none; convert to black and white and the green is no longer there and the specks now add character to the image.

Rather than try to save the green cast image with low visibility I converted to B & W.

3) When your image is monotone or when color is not a factor in the photo.
Monotone images are prime candidates for B &W conversion. Color is not a dominate factor in this image.

     I hope this tid bit of information will inspire you to dabble with your post processing conversion of color to awesome Black and White images. 

Good luck!
