Some pics from today at Flushing Beach. Above, a pair of Green shore crabs Carcinus maenas, below two Furrowed crabs Xantho hydrophilus. (I probably should have gone for a whole crab series, as I saw several other common species…) Instead I took loads of random photos, of things that were 150 mm to things that were only 5 mm, with varying success. For instance of a Painted Topshell Calliostoma zizyphinum on the invasive Bryozoan Watersipora subatra. Also the underside of the urchin Psammechinus miliaris, showing its mouth (Aristotle’s Lantern). Photobombing top left is the commensal worm Flabelligera affinis (which I noticed as well the last time I took a version of this picture). Bit random but it was fun practicing. It actually is more difficult to take photos abovewater compared to underwater due to the glistening and the awkward position kneeling on wet gravel/rocks. Next time I might try a tripod (ideally remote flash would be used but I do not think I am going to invest in that). Btw, if you are on instagram, I also post pics as @an_bollenessor.
A solo dive early evening at the Silver Steps site. It was a couple of weeks I last went, and this time it was already dusk when I entered the water. My intention was to find cup corals and other small creatures growing on rock overhangs below the kelp line. The viz was good and sure enough I found what I was looking for: Devonshire cup coral Caryophyllia smithii, a solitary stony coral which is relatively common. They are very beautiful and the right size for the macro lens. I will definitely go after them again. Other finds were a golfball sponge Tethya aurantium, a baby Longspined seascorpion (this shot had potential, but it swam away unfortunately), a tunicate and a Painted topshell (very common). At the end of the dive unfortunately it was getting too dark to find objects or too properly focus; I need to sort out a dive light!
A quick snorkel in the rockpools today. Tried to photograph some gobies and prawns but they were not very cooperative. I noticed a small clam under an overhang: the Variegated scallop Mimachlamys varia (old name: Chlamys varia). This species occurs quite commonly attached under rocks here, and although it can have all kinds of amazing purple, yellow and orange colours it is usually a dull brown. I managed a couple of OK shots; it is fun to see the rows of eyes. Definitely worth trying again (and going for a much bigger Scallop Pecten jacobaeus while diving should be fun too).
Viz at the south coast was bad last week, so I stuck to macro (=less water between the subject and the lens). In a particularly shallow pool, I noticed a couple of ‘subjects’; some tiny Mysis shrimp for example. I had a lucky shot of these with my old camera (see here), but could not get it right this time. Same for a tiny Polycera quadrilineata nudibranch. Then I noticed something bright red in the corner of my eye: a worm sticking out of its tube. It was so shallow that I had to remove my strobe from the tray and hold it in one hand. I believe this is a Serpula vermicularis (right next to it in the second photo is another species with a keeled tube). The red and white disc sticking out between the tentacles is the operculum used to close off the tube when the animal retracts (for instance, when you move your camera too close). Even the least exciting looking things on the shore become interesting and beautiful when you take a look up close!
I managed to squeezed two snorkel sessions in this week to practice with the macrolens. Today it was sunny and still, finally after weeks of bad weather. I returned to the same Rainbow wrack as pictured in the last post and found some other mollusc species but none of the shots worked. (Also, very annoyingly, I had not put the lens on the 1:1 macro setting meaning I had to get out of the water, walk back to the car to dry my hands, remove the camera from the housing, set the lens and then come back…) Because I always (and often) snorkel at the same spot, I know where certain individual seaweeds are. I returned to a Codium plant on which I had seen the solar-powered seaslug Elysia viridis before and found one, 1-cm long individual. I spent most of my time trying to get a decent shot of this slow, cooperative individual. I am getting the hang of it, and played around minimising depth of field to get more light in and to remove distracting background. The backscatter is still a problem. I think having a snoot could work wonders, but I probably should try to practice some more and not fall into the trap of buying new toys. I was too lazy to meticulously tweak photos on Photoshop but used Windows Photos to spice them up, see below for a before and after:
Last Sunday the weather was less good. Instead of lying motionless in front of a sacoglossan , I lay motionless in front of a European cowrie Trivia monacha. I could not position my strobe well, at least, that is my excuse. What is always interesting to see when looking at photos on the computer later are the other, even tinier, organisms photobombing such as this amphipod on the right side of the shell:
These photos are from a couple of weeks back; since the weather has been hideous most of the time I have not been out much since. More practice with the m.zuiko 60mm macro lens abovewater. Above a small Strawberry anemone. Below a small Cushion star Asterina gibbosa and my finger tip for size. Below that the hydroid Candelabrum cocksii and an Idotoea isopod species (there are several common Idotoea species but I have not paid much attention to them yet I must admit). Finally, the adorable Worm pipefish Nerophis lumbriciformis which is common and usually found in small groups under rocks (I have never seen them underwater as they are small, slow, well-camouflaged and probably hidden most of the time). Definitely will try to get some more portraits of these lovely fish!
I recently posted my first photos taken with the nauticam CMC macro wetlens using stalked jellyfish as a subject. I since lost my lens, which I in large part blame on the bad fit of the adapter with which it is attached to the housing. The best thing in these cases is not to agonize over it too much, order a new one straight away and keep going, so that is what I did (also I am now a bit more careful of course). Here some more photos of macro subjects. Above a very easy subject as it is very common this time of year and also it does not move….Paddle worm egg capsules (probably Eulalia viridis). The individual eggs can be just made out in the gelatinous blob. Below, one of the more common nudibranch species Polycera quadrilineata. Nudibranchs come in all kinds of stunning colour variations and are very species rich and so are a favourite of macro photographers (see this old post hunting for them with David Fenwick in Newlyn, and check out the NE Atlantic Nudibranch facebook page for lots of eye candy). Tricky with the narrow depth of field to get the whole animal in focus. Mysid shrimp are quite common and beautiful little animals hovering about in small groups. They need dissection to determine which species it is, but this might be Leptomysis lingvura (around 10 mm). Finally, the colonial star Ascidian Botryllus schlosseri; these form colonies (‘systems’) where zooids have individual inhalant openings and a shared exhalant opening. They are common, sessile, flat, and come in a range of colours so they make ideal subjects for a beginning macro photographer. Not only that, apart from fish they are our closest relatives in rock pools, which is most obvious in the tadpole-like larvae which have a dorsal notochord (a cartilage rod functioning as a backbone). I hope to devote a post to them later in the year.
