Rumours had it that the viz was great at the North Coast last weekend, and as it was pretty bad at the south Coast, I found some time to drive up to St. Agnes (buying new fins on the way) with the fisheye lens+dome. I was not disappointed: look at that blue sea! The water was clear, the sand was white and the seaweeds were waving on the rock faces. I saw flounder, mullet (thicklipped and red), seabass, sand eels, corkwing wrasse, sand smelt and most interestingly: weeverfish. Swimming above the sand with yellow fins and burying themselves so only the eyes are visible. I saw one half a meter deep on the beach, so it is advisable to wear surfshoes (see here). Unfortunately I could not get a good photo. I tried to take photos with the strobe but that did not really work so all photos here are natural light, trading off ISO, shutterspeed and depth of field to get the right exposure. There were Blue jellyfish around (small, 2-4 inches), and I tried to shoot them over-under but that was a bit too ambitious. Some easier shots instead. I hope to find some big Barrel jellyfish in the coming weeks, as they will be a lot easier to shoot! As the fish proved a bit too fast, and the over-unders a bit too difficult, I tried to take some shots of seaweeds instead. Although I mainly knew it from more sheltered locations, there was quite a bit of Mermaid’s tresses Chorda filum on this exposed coast. There was a lot of discoid forkweek Polyides rotundus on the sand but also on the rocks, and often covered in Falkenbergia. Other species that were abundant were Hairy sandweed Cladostephus spongiosus and Desmarestia ligulata. Hope to return soon!
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.
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:
I had my first two outings trying the the mzuiko 66mm macrolens with strobe this week. I managed to make some OK pics more due to luck than wisdom! It is actually not that difficult to find interesting subjects, but getting finding them back in the zoom finder is quite tricky (I usually point at a subject with my finger and then try to find a big white blob back when looking at my camera, then hoping to encounter the animal somehwre nearby). I managed to find a Least chink shell Lacuna parva spent on a Rainbow wrack Cystoseira tamariscifolia plant and spent 30 minutes looking at it. Although there is not much definition on this tiny (5mm) all-white organism, the blue background looks great. I will definitely go back to specifically look for (slightly bigger) things on Rainbow wrack! (The iridescence of this seaweed means that if the (strobe)light hits it at a different angle it is a dull brown rather than a deep blue or purple.) To give an idea of how tiny some things are see the photo above of the shell-less mollusc Runcina coronata (this is an ophistobranch, it does not have gills on its back as do nudibranchs), it was really, really tiny! This photo is nice for ID purposes but I do not expect I can take good photos of species this small (you reallly need an additional macro wetlens for that). I only later noticed the even smaller mollusc Flat skenea Skeneopsis planorbis next to it. (I identified this species using the excellent new Essential Guide to Rockpooling by Julie Hatcher and Steve Trewhella by the way, highly recommended!). I also noticed I need to clean my finger nails! (More tiny molluscs were present, including Eatonina fulgida.) Next, the mollusc Tritia reticulata (which I knew under the names Nassarius reticulatus or Hinia reticulata….) or Netted dog whelk in common parlance. These are very active and fun animals. The macrolens really brings out how battered and overgrown the shell is and the beady little eyes also stand out. A little hermit crab posed nicely as well. Another difficulty is working the strobe. Unlike the ‘normal’ ambient light photography I am used to, the image after clicking is different from that seen through the viewfinder so it is trial by error. Often the subject is not properly exposed. Also, floating particles cause backscatter. Perhaps I should try a snoot to minimise this effect, which can ruin an otherwise decent (in focus) photo, like this one of a Stalked jellyfish Haliclystus octoradiatus which are common at the moment. (Notice the tiny molluscs on the seaweed in the background.)Finally some random pics: a Light bulb seasquirt Clavelina lepadiformis, two colonial seasquirts (a Morchellium argus and a Didemnid species) and a Bryozoan (it is late and I have not looked up the species). A whole new world opens up if you look at the tiniest denizens of rock pools, all complex, colourful and fascinating!
Because of the plankton bloom (see the last post), I decided to try my hand again at some above-water macrophotography. Above and below a Flat periwinkle Littorina obtusata on bladder wrack. More subjects: a Red Doris Rostanga rubra, a Painted topshell Calliostoma zizyphinum, Cornish sucker (or Shore clingfish) Lepadogaster purpurea eggs (they must not be laid long ago and so the tiny fish are not yet visible, although if you zoom in you can see an outline forming) and some layers of Coral weed.
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.)
Yesterday I finally took my new camera underwater! I should have gone a bit sooner, but too be fair the water has not been looking very clear (and the viz was still not ideal). The sun was shining and it was great to be back in the water (perhaps 12C, not too cold with a wetsuit). It should be a great experience to shoot with a new, better camera, but it ended up being a bit of a frustrating experience not finding the right settings (I know, first-world problems!). I was stuck in Aperture Priority mode, which was a problem with significant wave action and the need for a fast shutterspeed. Although I took close to 200 photo’s, only a handful were halfway decent. Still, I learned a lot for next time. I took the 8mm fish-eye lens which allows you to get very close to the subject (especially useful for water that is not crystal clear) and still get a wide angle view. Above, a photo of an estuary sponge and seaweeds as well as Snell’s window. Below a badly composed shot of seaweeds, a downward shot of Furcellaria lumbricalis seaweed and Bushy rainbow wrack with Spaghetti weed in the background. All not very sharp and with flat colours, and hopefully standing in stark contrast to the next batch of photo’s!
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!
