13th April 2017 – Underwater

It has long been held as true that we know more about space than we do about our oceans. Quite possibly true, though I don’t know how you measure it, what I do know is that club member Julie Kaye’s presentation on underwater photography went down, if you will forgive the unintentional pun, very well. Julie brought her equipment as well as prints of her results and took us through the mechanics, the necessities of adapting the human body and her camera equipment to the realms where no human is naturally equipped but for the very briefest of visits.

 

The equipment needs are not merely image critical, they are life supporting and diving is a dangerous sport if the basics are not attended to.  The conditions under which you are shooting are a challenge too and this is one of the more difficult areas of photography to master. For those of us brought up on the Undersea World of Jacques Cousteau the mysteries of the oceans were a childhood staple.

 

Possibly most associated by most as branch of travel photography, the underwater milieu  goes back to the end of the Nineteenth Century, the first underwater camera and lighting rig was invented by another Frenchman, Louis Marie Auguste Boutan in 1893, when certainly photographs would have been taken but the oldest extant photo of a diver, a selfie by Boutan is dated to 1899 (and apparently damned near killed him through Nitrogen narcosis in the process). The gap is accounted for by Boutan’s work on a lighting solution, a highly explosive mix of oxygen in a barrel and magnesium powder to provide a flash held in a glass container triggered by an electrical current. Remember that film (read glass plate) speed was very low at these times with normal photographs being taken with what we would consider long exposures.

 

Prior to Boutan, the first person to take photographs whilst submerged, there had been underwater photographs but these had been obtained by using a camera in an almost-waterproof housing lowered on a tripod, was William Thompson, who took them in Dorset in 1856. Unfortunately the glass plates don’t seem to have survived.

 

Colour came along in 1926, National Geographic staff photographer Charles Martin and naturalist Dr William Longley taking a picture of a Hog Fish in the Gulf of New Mexico for that august journal. Following on in Boutan’s tradition they still executed the image with pounds of explosive magnesium flash powder. The difference was that they sensibly left it floating on the surface in a raft rather than build a submersible flash unit as Boutan had.

 

Cousteau remains the most famous pioneer though, operating from his famous boat the RV Calypso, which came to near sticky end in Singapore in 1997 but on which restoration work began last year (after a 20 year story worthy of a soap opera), he developed not only Scuba gear but the underwater camera as well. The Calypso, before coming in to Cousteau’s hands, was built as a Minesweeper for the Royal Navy and served as such from 1943 to 1949, then as a ferry in Malta for 4 months before being bought by Thomas Loel Guinness MP and leased by him to Cousteau for one French Franc a year on grounds of anonymity for Loel Guiness.  There were, at the time, around a thousand Francs to the pound, so bit of a bargain. For those of us brought up on the TV show (1968-1976 and endless repeats) the Calypso was as much of the show as Cousteau.

 

Cousteau wasn’t just an explorer (naturalist, conservationist, etc etc), he was an inventor too. He conceived the idea, which was designed by Jean de Wouters, of an underwater camera which was called, wait for it, the Calypso. It came with an f3.5 35mm lens, with 45mm and 28mm optional lenses and a shutter speed of 1/30th to 1/1000th of  a second shutter, which was redesigned to a 1/15th to 1/500th of a second range which was the one carried on to the Nikonos, licensed and built by Nikon, through three variants and which lasted in production until from 1963 to 2001. Basically it was killed off by digital but it is still to be found second hand.

 

Underwater photography is also a sport, not big here, admittedly, under the auspices of CMAS. The World Championships run thus: Basically at least four 90 minute dives (including decompression time) are undertaken and the first 100 images from the relevant memory card are downloaded and then the competitor selects which images go forward to (anonymous) judging. Then it gets complicated: ” During the last day of the competition, the jury will review all submitted images to rank these within the photographic categories described in the Specific Rules. An individual classification will also be compiled by allotting scores to the top ten images in each photographic category using a fibonacci sequence. The names of top ten competitors in the photographic categories and in the individual classification will be publicly announced.” Not so catchy, maybe.

 

There is a wider range of photographic equipment and accessories available to the modern diver, of course, specialist housing, lighting (non explosive), but all at a price and a half. It has to be precision engineered of course, able to withstand pressure greater than found at sea level and whereas it is popular with people on holiday (who can buy pouches and boxes for their cameras for shallow depths if their camera isn’t already waterproof) who go snorkelling, if you are serious and a scuba diver and a regular photographer, then the outlay garners the returns.

 

So a big club thank you to Julie for an interesting and unusual evening.

NB: The AGM has been postponed for a couple of weeks, our next session is table top photography so bring cameras, tripods and something small to photograph.
