Remote strobes

ERB_4588.jpgIt’s been a while since I played with remote strobes, so this weekend (having been been blown out by poor Bank Holiday weather) decided to try this technique in a local quarry. In a bid to get the creative juices working at a less familiar site, my buddy and I picked the National Dive Centre in Chepstow, a location I have dived less often than other fresh water sites in the Midlands.

The idea with remote strobes is to light a subject without using the strobes attached to the camera. This has the advantage of using a light source close to the subject but further away from the camera and so giving good lighting but with a minimum of backscatter.

The NDAC, like many quarries has a lot of scrap metal and I chose a Wessex helicopter as my subject. The aircraft was reasonably intact and has a large (dark) internal space. There’s a lot of setup time needed for remote strobe work and I was privileged to have a buddy prepared to set aside his camera and carry the extra strobes for me. It was just as well really, as of the two strobes I was hoping to place, one of them refused to work at all (despite having worked when I tested it before the dive). The vis was quite good (about 8-10m) and so I tried working from further back than usual, to catch the whole aircraft. I tucked the strobe (a Sea & Sea YS-110) inside the doorway, set on half power and pointing inward toward my buddy, who swam slowly out of the doorway.

The exposure was set as if for available light only, with the ISO high enough to provide a shutter speed fast enough to freeze the bubble motion (1/100s); since I was at least a few feet from the nearest part of the wreck, an aperture of f/8 was enough to ensure the whole frame was in focus. I used a single strobe on a low power setting solely to trigger the remote strobe.

I had my buddy shine a torch towards the strobe so that the flash light is “connected” to the subject. It takes a lot of practice to get all the aspects of this technique right and in hindsight, the strobe is not far enough behind the doorway, some flare is still visible. The diver is perhaps rather small in the frame and so the effect of the remote strobe is rather subtle; on the whole I think it needs a smaller subject, so that I can have the whole wreck but with the diver larger in the frame. Just another reason to go back and try again…

The Blue Lake

2017-03-18 09.52.48A dive in the clear blue waters of a secluded quarry, whilst the early Spring weather is doing its best to stir up the vis all along the coast? Yes please- win win, surely! Well, that was till I saw the hill I had to walk up to reach it!! The hidden quarry is located about half a mile along a very steep path leading up from the road.

The Blue Lake is a quarry near the Welsh coastal village of Fairbourne, on the edge of the Snowdonia National Park. It is a rather odd experience to march in scuba gear up a very steep hill and, reaching the top to see the coast spread right across the view, turn away towards the craggy rocks. The quarry is surrounded by cliffs on all sides, so can only be reached through a low tunnel, once used to remove the quarry workings. The Blue Lake fills almost the whole space as you emerge from the tunnel and is indeed very blue. This colour is due to the copper in the water which inhibits the growth of algae.

My buddy Trevor and I were hoping for some undisturbed, crystal clear water to practice some wide-angle photography techniques. The lake, though small was indeed very clear, though as with many of these places, the clarity is very easily disturbed with a single unwise fin-kick.

The sheer cliff wall led down to a gently sloping bottom covered in broken slate and the rusting odds and ends left over from quarrying. Depressingly there is also quite a lot of the evidence of summer barbecues- broken bottles, rusting cans and even one or two pots and pans.

We practiced some selfie shots- me by using the time honoured holding-the-camera-at-arms-length and Trev by using a Tripod. The main challenge was not stirring up the silt. Was the strenuous pre-dive walk (carrying the scuba gear) worth it? Well, it was certainly quite a different diving experience and I am glad to have done it, but I am not sure if I am going to be back. We gave the passing hill walkers a smile though!

1000th dive

I logged my 1000th dive whilst on this trip to the Red Sea. I know that this is not an especially remarkable total, but it is still a large number of dives for a recreational diver. It felt as if that dive should have been accompanied by fanfares and mermaids (or maybe one of the local Dugong).

However, it turned out to be quite a low key leisurely shore dive from the dive centre at Marsa Shagra. I think it sums up what I love so much about scuba diving- it was in the company of a like-minded buddy; in this instance we had been strangers 24 hours before, but we felt like firm friends after a couple of shared dives.

During the dive, I didn’t notice any species I had not seen before, but it was a pleasure as usual to waft weightless through the water. It has to be said that it was most welcome to escape the English winter and drift over a Red Sea reef in the late afternoon sun, observing the fish going about their normal business and shooting images as I went.

I saw a Stonefish hauling itself across the sand, a Lionfish hunting for prey and flocks of Goatfish prospecting in the sand. The Anthias were pulsing in and out of the coral heads, whilst Groupers drifted across the reef, hoping to pick off an unwary small fish. Humbug dascyllus played hide and seek among the branching corals, whilst iridescent Pale damselfish rose high above the reef feeding on tiny particles in the water.

Here’s to the next 1000 dives…

Stoney Cove

The first dive of the 2017 season was in Stoney Cove, my dive site of choice for a quick dip in the winter. There is always plenty to see and there are lots of subjects to practice my photographic technique on. This time I was joined by two fellow divers from the Bristol Underwater Photography group, Kirsty Andrews and my regular buddy Trevor Rees. The visibility was quite good and we were treated to some bright winter sun, which contributed to some very enjoyable shooting conditions.

Salcombe Pea Soup

Sometimes called by divers “May bloom”, “snot” or terms less repeatable in polite circles,  there comes a time each spring in temperate waters when there is an explosion in the algae population. So it was in the Devon waters I dived with my club last weekend. Its not often a trip is a photographic washout, but my recent trip to Salcombe was almost so. Last time I went, early in April the water was clear (but very cold) and the visibility was excellent due to bright sun. That same sun, a few weeks later had caused the same stretch of sea (East Rutts) into murky pea soup, with countless green spheres in the water column from the surface to below 20m. Conditions were not helped by choppy seas and overcast skies. Still, a bad day’s diving is better than a good day in the office, as they say….

I greatly enjoyed a trip to Devon last weekend and, though the water was cold, the visibility was surprisingly good. I managed four dives- two reefs and a wreck (twice). The reef, East Rutts was a very pleasant place to spend an hour and this early in the season is covered in Oaten Pipe (Tubularia indivisa) hydroids. Those hydroids won’t be around for very much longer, as they are the food for nudibranchs (sea slugs). We saw many spiral swirls of eggs, but no slugs yet, but I would expect that by May the hydroids will be gone.

The wreck was called the Riversdale. It’s large and intact (except for the bow), with an impressive rudder and prop. It’s a while since I dived and took photos on wrecks at this depth (38m to the deck) and, photographically it was quite a challenge, due to the narcosis and the limited time. Even with good vis, lighting is difficult. We dived it twice, on consecutive days, as we could not get the shot line up after the first dive, so had to leave it in overnight and send it up on a lifting bag at the start of the second dive!

The vis was very good (about 8-10m), but I could see the beginnings of a “May bloom” of algae in the top few metres. Let’s hope that comes and goes quickly and does not spoil the view too much.

Stargazing

This hermit crab looks for all the world as if he's looking up at the stars!

On a recent trip to Scotland, we were dogged by poor visibility. This image of a hermit crab (Pagarus bernhardus) shows how much silt was suspended in the water. This site was actually one of the better ones (the shore of Loch Sunart, at a place called Camas Torsa) and I like the way the hermit crab seems to be looking up into a starry sky. I find hermit crabs endlessly entertaining and I have mused about them before, but it did make me smile. This particular individual had lovely iridescent hairs on it which have been picked up by the well-snooted strobe. I was shooting using the Nikon 60mm macro lens on my trusty D200. The critter was conveniently walking on an old crate in the water, which provided a fantastic stage from which I could take his portrait as he looked up and wondered if alien life existed out there…
