Some photos from Last Sunday at Castle Beach in Falmouth. Above, the periwinkle Littorina littorea, which aggregrates in great numbers on the upper shore. Below, three echinoderm cousins: a Cushion star Asterina gibbosa and a little Sea cucumber Pawsonia saxicola with a Brittle star in the background. It was the first time I saw this beautiful colour variant of the Risso’s or Furrowed crab Risso pilipes. More common is the very similar Montagu’s crab Risso hydrophilus, there are usually 5-10 individuals under a single rock. The small ones especially come in a range of colours that make them excellently camouflaged against the pebbles. Next a juvenile Shanny Lipophrys pholis, a detail of a Corkwing wrasse (I could pick it up, that is how low the tide was) and a shot of the beach, showing the versatility of the mzuiko 60mm lens.
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!
I will keep this post short, as my third Silver Steps shoredive of the year was a week ago. As you can see above, my dive was made by encountering the beautiful nudibranch Antiopella cristata (although I prefer the old name Janolus cristatus…). My camera battery strangely gave up straight after taking these pics (argh!), otherwise I would have bothered it for at least another ten minutes! The 60mm lens is great. Look at the European cowrie Trivia monacha below which is less than a centimeter in length. Not a great shot but it shows that it is possible. Finally, a common Phoronid worm Phoronis hippocrepia (Thanks Allison, please check out her great blog Notes from a California naturalist). I hope the wind will die down and I can go back soon.
Another Silver Steps shore dive with @shannonmoranphoto and her fellow student Chris on Friday. The conditions were not as good as last time: low viz and a bit of a swell. I had set my camera to a longer focal range to try to take pics of cuttles or larger fish but that did not work out (with better conditions it still might not work out!). I could still shoot macro so that is what I did. Above to Devonshire cup corals Caryophyllia smithii. Pretty decent, but I know I can get a better close-up; I will try again Monday! I will have another go at the one resident Cray (or Craw) fish, which lives very shallow. I will also try the Twin fan worm Bispira volutacornis again, as I think a shot filled with just the fans (and not assorted bits of seaweeds etc) could be really nice. I might try free-swimming fish if they come close, as did this Poor cod Trisopterus minutus. Below some before- and after postprocessing. Just the jpegs in Windows Photos, nothing fancy. A bit of cropping, increasing clarity and contrast works wonders. Only when I have a really good photo I will invest time processing raw files in Photoshop. First the best photo of the dive: a Black-faced blenny Tripterygion delaisi (a female or possibly a non-breeding male). Next, a common Edible crab Cancer pagurus and finally a Twospotted goby Gobiusculus flavescens.
Finally a shore dive yesterday evening, it has been a long time. I partnered up with buddy Shannon via instagram (@shannonmoranphoto). Instagram has been a really nice way to learn about photography from likeminded folks (such as @danboltphoto and @malcolmnnimmo). We dived (dove?) Silver Steps in Falmouth, about which you can find a bunch of old snorkelling and diving posts on the blog if you are interested. Shannon was the ideal buddy: relaxed and really into photography, so we kept the same tempo. It was a very shallow dive (maybe 5 meters), so we were only limited by getting cold, which was after an hour. I chose to use my 60mm lens, but not to use the 1:1 macro setting, but the 0.19-040 focal range to try my hand at slightly larger objects such as fish. I was thus lucky in a sense that I did not encounter any beautiful nudibranchs of which I would not be able to to take a good shot. (Edit: actually, I since learned that 1:1 is still possible using this focal range). It was however unfortunate that I could not get a good shot of a cuttlefish that hovered about two meters away, rapidly changing colour and catching a wrasse! Next time I will perhaps change settings again to try my hand at (cuttle)fish swimming a bit further away. However, I was very happy with sticking to Leopard-spotted gobies Thorogobius ephippiatus. They do not stick their little faces out of nooks as do most blennies, but usually lie on and under ledges. The trick was to approach very slowly, shooting until they swam off. For some reason, I managed to position my strobe right and did not have backscatter issues. I used Windows Photos to postprocess. See below for a before and after example: Two other common organisms below: a Squat lobster Galathea rugosa and a Twin fan worm Bispira volutacornis. And finally an out of focus, but fun photo of a tiny tiny clingfish very aptly clinging to Shannon’s housing. This was one of the most fun dives in ages and I hope to repeat it sometime soon!
Facebook/instagram and even news websites have been awash with Barrel jellyfish photos and videos the last week and so I had to get a piece of the action! I had seen these gentle giants in previous years but had not tried to take any photos in earnest. I snorkelled out from the beach in Falmouth and after 200 meters or so I sure enough found three or four (they occasionally came close to each other but there of course was zero interaction). Barrel jellyfish Rhizostoma pulmo can in rare cases have a bell 90 cm wide but these were smaller, maybe 90 cm in length. I dove to take shots from below again and again: good exercise! I learner to hold my breath so the shot would not be ruined by air bubbles. I tried some over-unders but the shore was far away and so ended up only being a sliver, tricky!I tried some downward shots as well, which were much more gloomy. I saw a lone Blue jellyfish and a couple of Compass Jellyfish Chrysaora hysoscella. They are much smaller and have longer tentacles that unlike the Barrel jellyfish can sting (but not badly). Jellyfish are a great subject, beautiful and not rapidly swimming off! I hope to go back soon and try some more shots. (I will have to make sure to wipe the dome port occasionally as I had to spot-fix quite a bit).
What friends predicted happened last Sunday morning: someone scrambled down the rocks to check if this figure lying motionless in a shallow pool was dead or alive. Luckily, I was feeling very alive indeed, watching a sizable Spiny starfish Marthasterias glacialis moving over the rocks using its hydraulic tube feet. A beautiful blue-grey colour, the surface of these animals are very richly textured. I am not sure exactly what is going on at the tips of the arms: the very end shows a red organ, potentially light sensing. It is surrounded by nodules, which might be the precursors of the centres of new plates covering its body, or something else. The tube feet at the tips are smaller and orange-tinged and I am again not sure whether they are just newly developing or having special sensory functions. I noticed the madreporite at the top of the animal: this sieve plate is involved in pumping the water in the body for hydraulic locomotion. It resembles a stony coral ‘madrepore’ colony, hence its name. In general, the seastar surface resembles a coral I think. The photos are nice, but I know I could do a lot better: next time!
I am running out of original blog post titles; these are just some more macrophotos practicing with the mzuiko 60mm lens. Friday afternoon was a gorgeous sunny, windstill day here in Falmouth. Although I somehow did not manage to find a stalked jellyfish, there were plenty of other things to see floating around in the shallow pools. I tried my hand again at the European cowrie Trivia monacha (see last post) with better results. It is hard to get the strobe position right, so I now hold it in my hand (rather than attached to the ‘tray’ that also holds the camera) to try to take as many different shots as possible. Below, a small Light bulb seaquirt Clavelina lepadiformis and the colonial seasquirt Morchellium argus. Finally, I noticed a shanny Lipophrys pholis hiding in a crevice. It was too large to capture its whole face with the macrolens so I tried to get one eye at least. It will be fun to try to get some fish portraits next time. Btw, catch me on instagram: @an_bollenessor.
A sneaky worktime dive today: the weather was beautiful, sunny and windstill and the tide was great. However, unfortunately the water was one turbid mass of snot: the spring plankton bloom has started! It was impossible to take good photos; with a fisheye you can get very close to the subject (CFWA ‘CloseFocusWideAngle’) minimising the amount of snot between subject and lens, but this only works up to a point! I had a go anyway. The seaweeds are in decline as well, see the fuzziness of the iridescent Osmundea truncata above. Below some shots of my alltime favourite the spectacularly iridescent Bushy rainbow wrack Cystoseira tamariscifolia: Finally, the species Gelidium attenuatum (?), a common, thin and shiny species I would like to know the identity of, a rock with lots of buttons of Himanthalia elongata and a Snakelocks anemone amidst the Harpoonweed. Not sure when the bloom will be over, but I think I won’t bother going back over the weekend!
Last weekend it was THE BEST weekend in the year for seaweeds here in Falmouth: the short window where most species peak (just before the bluebells are flowering on land), with a low tide, flat seas and sun. Unfortunately I was still waiting for my my new camera to come back from repair, which was very frustrating…. I took some pics with the Canon Powershot instead, but they are not really worth posting. I finally got my camera back last Tuesday: no damage to the lens but some replaced camera parts; with a bill under £150 it could have been a whole lot worse. As soon as I received the camera, I drove to Castle Beach and went for a 2.5 hour snorkel. The weather was not great, and the viz was neither. I took my strobe but that ended up in a big scatterfest so I quickly proceeded without it. First some general impressions of the rock pools with lots of Sargassum, Jania and Ulva. I also noticed quite a bit of Desmarestia ligulata (3d pic down):
I went fully Manual, varying ISO, shutterspeed and aperture which went surprisingly smoothly. The bad visibility and overcast skies however made it tricky to get good results and most photos were underexposed (of course still with some blown highlights). Also, I noticed the 8mm fisheye results in quite a bit of distorsion around the edges, more so than the wetlens I am used too even, which is slightly disappointing (but partially solvable by cropping). I tried a quick over-under shot which will I will practice more using a strobe (as the above water part is much brighter), but the main challenge will be to find a background that is more interesting than a bit of rock! Having a camera+ lens in a housing rather than a wetlens stuck on a housing is a huge improvement but I stilll have issues with having lots of bubbles on the dome. The seaweeds are happy at the moment and photosynthesising lots. The pic below of Harpoonweed Asparagopsis armata shows all the oxygen bubbles on the plant. Next, two photos of False eyelashweed Calliblepharis jubata and of Beautiful fan weed Callophyllis laciniata (I think!). Finally some animals. I discovered a small (3 inch or so) and exquisetly camouflaged Longspined scorpionfish Taurulus bubalis under the Thong weed, can you spot it? This is a shot that really needed a strobe but alas….Snakelocks anemones Anemonia viridis are common here. Again this pic is a bit underexposed and the vibrant colours do not come out but it shows the beautiful shape of this animal at least. What I need to do the coming months is too practice (especially with the strobe) so I will be well-prepared for the second seaweed season in autumn! (See the ‘2017 Falmouth Seaweed’ tag at the bottom of the webpage for posts showing how seaweed species wax and wane over the year.)
