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!
One of the nice things about Cornwall is that there are so many coves and beaches, that even after seven years of living here, there are still plenty left to discover. This weekend we visited Kennack Sands on the Lizard peninsula. Two fine sandy beaches separated by a small hill and a rocky outcrop in the sea. What I also like about Cornwall is that every rock has a name. The rocks we explored are called Caerverracks. The tide was pretty good, the weather as well (except for a brief shower). The viz however was quite bad, and so I hope to go back one time when the sea is flat to retake some of these pictures. The rocks did offer some shelter though and it was great to be in the water. I focused (no pun intended) on a type of kelp called Furbellows (Saccorhiza polyschides). It is called that way because of the ruffles on the stipe (in dress-making, furbelow is another word for ruffle). These wavey frills help to dissipate wave energy, which of course can be very intense on Atlantic shores. This seaweed is much more prone to epiphytic groth than the surrounding Laminaria kelp. This must be the reason why it is always covered with grazing Grey topshells Steromphala cineraria. As with other kelps, it is home to the Blue-rayed limpet Patella pelucida. As the conditions were bad, I was forced to limit myself to a large, abundant and non-moving subject, but it was actually quite nice to work within such constraints. One of my favourite seaweeds and when conditions are better (and when I am by myself, with more time and a weight belt so I can dive down instead of holding the camera down and shooting ‘blind’), I definitely want to try again!
A bit of practice with over under shots two weeks ago when camping near St. Michaels Mount in Marazion. An ancient and beautiful backdrop to a fine sandy beach, with a causeway, rocky outcrops as well as seagrass. I was not alone and did not have much time and importantly no strobe handy, which made the exposure difference between under- and above water tricky. The main problem was however that I could not get up close to the Mount, leaving it quite small in the composition. Still, a great hour in the water. Many two-spot gobies were around and this is a site with lots of egg cases of the Nursehound (or large-spotted dogfish, or greater spotted dogfish or bull huss) Scyliorhinus stellaris.
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).
A whole bunch of photos of yesterdays snorkel at Castle Beach. The viz has cleared up, although nothing like the fabled June 2017 viz, will it ever be as good again?! (see here). There are lots of yellows and browns, some greens, a substantial dash of blue of the rainbow wrack but hardly any reds and purples at this time of year. The glow of the sun exarcerbates the yellowish vibe, but somehow I suspect the colour temperature of the Olympus somehow is a bit off compared to my old Canon. I am not entirely sure about this though, and in theory this is all correctable postprocessing, I just don’t know how! The photo below shows some of the common species, from the bottom right to top left: Cladostephus spongiosus, Dictyota dichotoma, Asparagopsis armata, Cystoseria baccata with Sargassum muticum in the background. Ij the second photo it is obvious that the Wireweed and Rainbow wrack are quite dominant, same for the Hairy sandweed Cladostephus spongiosus. The Thong (or Spaghetti) weed is covered in fuzzy epiphytes. I will keep practicing for when the reds and purples come back in autumn!
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!
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!
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!
