Sulawesi: twice the size of the UK, volcanoes galore, uninhabited islands, strange creatures, boiling seas, electrical clams and tons of bioluminescence, all wrapped in the blanket Mother Nature's beauty and durability.
In January, we planned a dive trip to Halmahera, but the volcanic eruption Gamalama nixed that late December. The only positive aspect of the detailed planning and flight expenses was learning to spell words like "Halmahera, Ternate, Gamalama 'and why we should not cancel Garuda flights less than 72 hours before departure! Once the ashes settled and Ternate airport reopened, our dive charter boat was long gone in North Sulawesi, with no possibility of return
Fate seems to have a way of working on the issues here in Indonesia - . Our flight on Garuda airlines went smoothly, with all eight of us arriving in Manado both Jakarta and Bali in mid-morning. From there, he was driving east towards our liveaboard dive boat parked in the port Lembeh an hour. By 2:30 p.m. we were steaming in preparation for our first dive.
This adventure took about 100 kilometers northeast of Manado in many volcanic islands. We had the chance to experience two spectacular night dives, one off the south coast of Bangka Island and the other in the Lembeh Strait itself. On these dives I focused on capturing the town miraculous marine bioluminescence in these waters.
Most people have experienced the luminescence of microscopic phytoplankton, but what I mean is the real light output from higher marine organisms such as corals, anemones and little critters when they are subject to (or excited) a spectrum of blue light. There have been a number of written research articles on this subject, but it does not yet understand the true fundamental objective of animals with bioluminescence. Postulation focuses on the defense mechanism (to confuse predators), reproduction (to attract a mate) or to attract prey. Communication can be a primary objective for the creatures of the deep sea.
Bioluminescence is the most effective method in the world for the production of light. Most of the emitted light is green, blue or reddish color. These are the wavelengths of colors that penetrate better seawater. Some of these organisms does not themselves a fluorescence, but result from symbiotic hosts such as bacteria and / or algae (as in if coral) luminescent. The researchers studied marine luminescence since the early 100s
method to display and Photo Marine bioluminescence
First of all, please keep in mind that bioluminescence is not phosphorescence. Phosphorescence is a release of light from the oxidation of crystals, which are activated by light or radiation, while bioluminescence is a complex chemical response that releases the light when excited. Bioluminescence is highly evolved in the marine world, but normally goes unnoticed, that the emitted light can compete with sunlight or a strong torch underwater.
The equipment you need to detect the luminescent subjects is a dive light with either a UV option or with a blue filter placed over the lens. A better solution is to apply a blue gel filter over your dive light and look through a yellow filter is placed on your mask or in a small frame. The yellow filter cancels the blue light, but allows luminescence to shine through. What you see using this method are only the luminescent subjects, while the rest will be completely dark.
I use an i-Pro torch-6 with UV light option while diving for analysis to subjects. The ultraviolet spectrum is not the best wavelength to excite ', but it works pretty well as a screening tool. Fortunately, the UV lights up the surrounding area, making for a more comfortable night dive. Whichever method you use, try to divorce you little from the rest of the dive group (with their 00 lumen diving lamps) to see these subtleties. Just enjoy the peace because you are basically swimming in the dark, except for these glowing creatures.
To photograph subjects, you will need to attach a set of blue filter on your flash or strobe and a yellow filter on the camera lens. You can do this or if you're lazy like me, just buy a NightSea Fluorescence excitation filter that screws on the front of the flash. This filter commercially available screens on all light except that the wavelength of 510 nanometers. You will also need a yellow filter on the camera lens.
Once a creature or coral show as "popping" come in close to compose the image. It is best to have your dive buddy hold the UV or blue light filtered diving on the subject to get a good focus. I use the light focusing on my fancy strobe for it. It is best to use a setting high enough camera ISO (800 to 1.500), as the blue filter absorbs much of the light from the flash. I use a 60mm macro lens for this purpose. Pull manual if your camera allows. Experiment a little and take several pictures of the support to get the best exposure. Have fun!
Rule number one is do not lose your dive buddy (woman) you fool around. No matter how your image is, it is not worth it. Instead, dive together and have her shoot
