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.
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!
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!
Was last Wednesday the last sunny day of the year? It might well have been and so it was good I had taken a day off to drive to the north coast for some rock pool snorkeling at Trevose Head near Padstow. A beautiful, empty beach at Booby’s Bay led to the low cliffs of Trevose Head. I did not make it that far up the headland as there were some deep gullies and the waves were pounding below. If you slip and fall on your head you could be in real trouble on these solo outings, so easy does it. Like St. Agnes and Fistral at Newquay the pools were dominated by Brown fork tuning weed Bifurcaria bifurcata, one of my favourite seaweeds and not a species I have ever seen near Falmouth. In contrast to my local Castle Beach spot, the coral weed Corallina officinalis was not bleached but a deep purple and growing much more vigorously. I lowered myself in some of the deeper pools and although the viz was not the greatest I instantly knew the trip was worth it. I tried to get some overall impressions of the pools. What would be really cool is to try to make panorama photos underwater; I might order an underwater tripod for that! There was some green Ulva, a variety of small red seaweeds and Bushy berry wrack (and a little bit of Bushy rainbow wrack) and Sea oak with the same colour as the tuning fork weed. Many limpets were covered in quite a big variety of seaweeds. Not many shots came out well (due to the strong light, overcast days might actually be better) but it would be fun to do a post just on limpets and their mini-ecosystems of epizoic seaweeds. The pools are teeming with Montagu’s blennies Coryphoblennius galerita, I would say more than 10 per square meter. They are very curious and swim up to you, although the little ones then are so skittish that it is still tricky to get a shot. The fish below was a very good model though, quiff up high. Only through this close-up shot I noticed the strange flaps in the corners of it’s mouth. The blueish spots seem striking but also make for excellent camouflage amidst the coralweed. Beadlet-, Strawberry- and Snakelocks anemones were common and I also spotted large Dahlia anemones and small Daisy anemones. I saw a large (for the species) Gem anemone Aulactinia verrucosa as well. In the sun, my wide angle wetlens diffracts ligth on the subject which usually is not what you want but resulted in an interesting effect in the second image of the retracting anemone.
Finally, the bright red seasquirt Dendrodoa grossularia which I remember seeing before in Falmouth without realising what it was (the squirts are very small and clumped together). A green stalked jellyfish Haliclystus octoradiatus attached to coral weed unfortunately is not in focus but I like the very striking colour contrast. If only I could get my strobe to work and get good macro shots! This has the best north coast rockpooling site so far and I’d love to go back as soon as the weather (and tide) allows!
I have been out twice this week with the Canon G16 with the hope of snapping a few good photos (out of the hundreds I take). It was trickier than usual, in part because the viz was not great but also because I am making a bit less progress I feel. Investing in an expensive DSLR + housing will get me further but I do not know if it will be worth the money. However, I still have a lot to do when when it comes to mastering the principles of photography, especially getting to grips with manual settings. In this post I will highlight some of the ‘issues’ am facing; who knows I will be lucky and get some feedback via the blog (and instagram), sharing is caring! As usual, I focussed on the seaweed diversity, although at this time of year it is not the best looking. The photo above is nothing special (the seaweed looks a bit straggly) but I like the blue background. It is interesting the wide diversity of seaweed species on the Red rags in the photo below and I like the contrast of the green sea lettice versus the brown Bushy berry wreck in the second photo but both pics are a bit meh. A main difficulty is that many times the sand (orthe bleached coral weed) contrast with the subject of the photo resulting in excess highlights. I try to counteract this by reducing F-stops (resulting in an overall darker picture) and reduce highlights during post-processing. @chris_exploring recommended to choose overcast rather than sunny days which is probably the best approach (and I will have plenty of opportunities to test this the coming months!) The first pic below of a Two-spotted goby is OK but I could not get quite close enough. The second photo is of course out of focus but I included it anyway to show that some of these photos have great potential. It inspired my own photography rule (the ‘Vos Index’): the beauty of the subject (on a 1-10 scale) times the difficulty of a shot (on a 1-10 scale). We are all trying to score a 100: a perfect capture of a beautiful organism. I am stuck with mediocre captures of beautiful things. Sometimes I get a very good capture but then mostly it is of something not-so beautiful. I shoot JPEG + RAW, which is a bit of a pain as I do not want to clog my hard drive and reviewing and deleting JPEGs and then having to filter for names to delete the associated RAW files is annoying. I actually keep few RAW files because very few photos are worthy of any advanced Photoshop editing, and also the standard Windows photo editing software is not half bad. For example see the photo below of whitebait (impossible to tell if it is herring, sprat or pilchard). It is very low contrast and bluish; by reducing highlights, increasing ‘clarity’ and a bit of cropping the image is completely transformed (although still relatively unusable as the resolution is quite bad). Finally macro. I just cannot seem to get my strobe to work which is annoying so the pics below are all ambient light. I need to up my game with this as there are so many cool subjects around to shoot if you take time to look. Below some tiny (3-4 mm) snails Rissoa parva. I wanted to zoom in more but was unable to unfortunately. Next a much bigger (2 cm) Netted dog whelk Tritia reticulata (sigh, I knew this as Nassarius reticulatus, and Hinia reticulata but the name has changed again). Next, a baby (3 cm) Tompot blenny Parablennius gattorugine which are one of the easiest fish I know to photograph, not very shy! Finally another challenge to photograph, a mermaids purse (egg case) of a Nursehound Scyliorhinus stellaris shark with a tiny (2-3 cm) embryo visible. I had a little light with me that I used to illuminate it from the back but this could be improved upon as well!
I did a little ‘recon’ last Sunday in beautiful St. Agnes on the north coast but my timing was a bit off (the tide came in, with sediment getting suspended and the water becoming super-oxygenated, resulting in lots of bubbles on the wetlens). Luckily, this Thursday with no wind, the sun out and low tide, I had the opportunity to nip out again: awesome! Trevaunance Cove has a small beach, with rock pools on either side, I chose the Trevellas Cove side. Coincidentally, Shoresearch Cornwall (facebook here and here) had a survey and so caught up with Matt and Adele as well as Thomas from HydroMotion Media who I had not seen in a while. The north coast is quite different from the south coast I am used too: more exposed and this site for instance had none of the long Thong weed and Wireweed which dominate Castle Beach. The pools are also wider and in parts have a rocky, gravelly or sandy bottom. One spot had a considerable rock overhang, and I probably spent a full hour alone just at these six meters or so as there was so much to see. With the tide out, it was only about half a meter deep, with rocks encrusted in purple corraline algae, pink and orange sponges, bryozoans, tunicates and red seaweeds. The over-under shot is not particularly great but gives a rough impression, as do the two underwater shots (note the mysis shrimp in the last photo): There is a great diversity in red seaweeds, but I find these species quite hard to ID. The red rags Dilsea carnosa look pretty ‘ragged’ in Falmouth at the moment, but in this shaded, high wave energy spot they looked very fresh (first photo). I made a lot more photos but I was really struggling, as the bright sun reflected on the sand, with the seaweeds sticking out from the shaded overhang, such as Sea beach Delesseria sanguinea. The third photo give a good impression of the beauty of this habitat. Black scour weed and Discoid fork weed manage to scrape around in the shifting sands. Serrated wrack hangs and drips from the rocks into the pools below.Apart from the mysis shrimp in the water column, very large prawns patrol the rock surfaces and Edible crabs, Velvet crabs and Spiny squat lobsters hide in crevices. The prawns are curious and really beautiful. Most spectacularly, I found a large lobster in a cavity and at one point had a small lobster walking over to me: Many fish could be spotted as well: Topknots are common (you can just about see one glued to the rocks behind the lobster in the photo above) and there were a couple of big fat Tompot blennies around as well. Dragonets patrol the sand and are very well camouflaged (and hard to approach). A juvenile fish was hiding on and in a sponge; I first thought it was a juvenile Black-faced blenny Tripterygion delaisi, but in subsequent facebook correspondence thought of a Montagu’s blenny Coryphoblennius galerita (very common here) but then settled on a little Tompot blenny Parablennius gattorugine. This would have been a very good subject for a proper macro-shot if only I could get to grips with my strobe! In general this was a great place and time for fish. Apart from the topknots, tompots and Montagu’s blennies (juveniles were abundant, present even in the tiniest pools), I saw sand eels, corkwing wrasse, a pollack and horse mackerel (both a bit lost in these shallow pools), corkwing wrasse, shannies, sand gobies and rock gobies. I thought I spotted a Giant goby, but this turned out to be a very large rock goby Gobius paganellus (thanks Matt Slater). After the large goby photo, a tiny Rock goby (I think), a Shanny, a Cushion star and Snakelocks anemones. I cannot wait to get back to this beautiful site, but will need to wait a bit for the next good tide…
It had been over two months since I last went snorkeling at my spot in Castle Beach. Although I did go on two boatdives (with no photos to show for), let’s say the work-life balance was tipped in the wrong direction. However I had time for a low-tide snorkel this Saturday and it was great to be back in the water, with a Curlew as my only companion. It was the plan to practise strobe photography but unfortunately I did not manage to get my settings right and I was going nowhere. As this is an activity that is supposed to be fun, I decided to ditch the strobe and stick with natural light. Fish I spotted were Ballan- and Corkwing wrasse, two-spot gobies, tompot blennies, a fifteenspined stickleback, a dragonet and sand eels: It is pretty much the worst time in the year for seaweeds but the pools are still quite pretty. The first three photos give a general impression of the seaweeds, including Thong weed, Harpoon weed and Irish moss. After that: Codium spp, Juicy whorl weed Chylocladia verticillata, a big plant of healthy-looking Hairy sand weed Cladostephus spongiosus, withered Red rags Dilsea carnosa and Dulse Palmaria palmata growing on a kelp stipe. I called it quits after two hours. On my way back I noticed an abundant green algae species I had not seen before. David Fenwick identified it as actually being a cyanobacterium rather than a seaweed: Rivularia bullata, interesting! Hope to do a lot more snorkeling before it gets too cold…
Yesterday I went for a late morning snorkel; although the water looked inviting, the viz was disappointing. I did not see anything of interest until I noticed a Seabream (15-20 cm) hanging about, not a species I had seen before! It goes to show that there is no dive or snorkel session whithout something that makes it worthwhile. The fish was not very shy, but I did not have weight or fins so I could not get down to get a proper shot from the side. I found out that this was a Gilthead Seabream (Sparus aurata). This southern species seems to have become more frequent on the South coast of the UK the last few years, probably due to warming seas. It seems to be known among anglers, but less so among underwater observers (the NBN Atlas only has two records for this species in Cornwall). Other than that the usual Ballan- and Corkwing wrasse, Two-spot gobies, Pollack and even a Blenny (very commonly found under rocks while rockpooling but I hardly ever see them when snorkeling).
It was time this Saturday: my first dive of 2018! Leaving with Atlantic Scuba‘s Stingray rhib from Mylor Harbour, we plunged in the cold (9°C) water above what remains of the N.G. Petersen in Falmouth Bay. Frustratingly, the indicator light of my strobe kept flashing red and green, so taking decent photos was out of the question. Luckily, I am able to post a nice little clip of this dive made by fellow diver Glyn Kirby (thanks Glyn!). It gives a good impression of life on the wreck and the plankton bloom, reducing the viz quite abit. Inbetween the rubble, some urchins, edible crabs, spider crabs and lobsters. Also great to see five or so (small) Rock Lobsters and some wrasse and shoals of Bib (with some other gadids hanging about too). We saw a small freeswimming Conger Eel and a very big one sticking its head out of a tube (photographic evidence below the video, such a shame the flash did not work because the angle I got was nice). All in all a good dive together with excellent buddy Al. More diving soon I hope!
I had the pleasure to go on two dives with Mark Milburn of Atlantic Scuba on the ‘Stingray’ RHIB this weekend and last, leaving from Mylor Harbour (see photo above). The first dive was in the Helford Pool, a deep area in the otherwise shallow Helford river. Buddied up with Sue and Al, we descended to 18 meters to swim over a gravelly area covered with tunicates and sponges. This was a drift dive but we did not get all the way to the eastern end of the pool where some small maerl beds are located. Swimming crabs and Leach’s spider crabs were very common; there were not many fish though. One exception was a cute little John Dory Zeus faber. I was struggling to take any decent photographs, in part because I have not used my strobe much yet and because I should have two, not just one! Sue Barnes kindly let me use a photo she took of the John Dory for the blog; also added is a photo of a sponge, one of the few half-decent ones I managed to take: The dive today took us to the cannon ball site, roughly a mile from Pendennis Castle, and an area where many of the cannon balls fired for practice ended up. With buddy Alex we descended to around 16 m using a shot line. Again a flat ‘rubbly’ area with few fish. The seafloor was covered with Common brittlestars Ophiotrix fragilis. The viz was quite good, and it was much lighter than the previous dive. I also had *a bit* more luck with the strobe. Leach’s spider crabs were common, and we also saw some Sea lemons, Doris pseudoargus, a large seaslug. Up next three common species: a little Rock goby Gobius paganellus, the colonial Antenna hydroid Nemertesia antennina and the colonial sea squirt Aplidium elegans (thanks David Fenwick). I keep my eyes open for seaweeds too of course, there were some small red species and what I suspect is Desmarest’s prickly weed Desmarestia aculeata. I found out back on the boat that I completely missed a small octopus that Alex pointed out, argh! I was very happy though that I managed to spot an Imperial anemone Capnea sanguinea, which is an uncommon species. The photo of this all-white individual was taken without a strobe; I really should have taken more time to get a decent shot. A good reason to go back though, and maybe we can spot some cannon balls then too. The water is 13-14 degrees and so it is still doable to dive with a wetsuit.
