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!
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).
A quick post to keep the blog going. Seaweed season has passed me by a bit, first because of the bad weather and second, when the weather was better, because I did not have much time to go out. I went snorkelling only twice in May in my usual (shallow) spot at Castle Beach in Falmouth. On the 13th of May the plankton bloom was in full swing: a (wannabe) photographers nightmare! Generally, the seaweeds at this point were already a bit ‘over the hill’. I managed to get a nice shot of Berry wart Cress Sphaerococcus coronopifolius though (above). I also glimpsed what I believe is Iridescent Drachiella Drachiella spectabilis under a rock overhang. The bright blue Bushy rainbow wrack Cystoseira tamariscifolia contrasted very nciely with the deep red of the Red rags Dilsea carnosa, I hope to get a much better picture of that (probably next year…).By the next snorkel session the 19th, the visibility was much better. Some photos of the green seaweed Codium sp., A Gelidium sp. (pulchellum?) and a patch of Slender-beaded coral weed Jania rubens growing epiphytically on Hairy sponge weed Cladostephus spongiosus with the very common species Ulva and Oyster thief Colpomenia peregrina (and others). Next, Beautiful Fan weed Callophyllis laciniata and another Berry wart Cress Sphaerococcus coronopifolius. Finally, three shots giving a general impression of the seaweed growth and what I think is Chipolata weed Scytosiphon lomentaria as well as a snakelocks anemone inbetween yellowed False eyelash weed Calliblepharis jubata. About the animals: there are some juvenile pollack around, as well as two-spot gobies. I saw a brown, flabby shape drifting through the water at one point and my first thought was that it was a seahare but it actually turned out to be a small clingfish (I could not get a photo unfortunately). There were quite some polychaete worms erratically swimming around in their reproductive ‘epitoke’ stage. The final photo shows one (with a Nassarius reticulatus in the background) which could be Perinereis cultifera.
This Thursday was only sunny, but also not windy, with a good low tide in the early afternoon, which meant I reserved a few hours to go to Tunnel/Castle/Gylly beach for some snorkelling. The photo above shows Gylly Beach, with the start of Swanpool lagoon behind it and the Lizard in the far distance. (I took this with my iPhone using a Hipstamatic filter; for more iPhone pics of Cornwall see cornwall_hipsta on instagram…). The water temperature was OK (9C?) but the viz was not as good as I hoped. The seaweeds are at their peak now and the pools looked very pretty. Not many fish, but I saw a small brown thing floating around which I first thought was Sea hare, but turned out to be a small (perhaps a Connemara) clingfish lazing about until it noticed me and bolted into the seaweeds. I carefully snorkelled in about half a meter of water, admiring the views and trying to take photos close-up (as the viz was not too good) with my wide angle wetlens. Below an above-water shot of some iridescent Bushy rainbow wrack Cystoseira tamariscifolia and the invasive red Bonnemaisonia hamifera (on the left). I need to go back studying photography basics. A main challenge is contrast. The pools have beautiful white sand, which result in hugely overexposed photos (or completely darkened subjects). I have come up with my own law, the Photography Frustration Index (PFI): the beauty of the subject (B) x the difficulty of capturing it (D). The PFI is very high in the case of seaweeds! Next: Bushy rainbow wrack under Thong weed, Purple claw weed Cystoclonium purpureum, Bushy berry wrack Cystoseira nodulosum covered with the epiphytes Asparagopsis (left) and Bonnemaisonia (right), Hairy sand weed Cladostephus spongiosus, Black scour weed Ahnfeltia plicata (you can see they grow in the sand and must be used to scouring) a ‘bouquet’ of different species (with a snakelocks anemone) and a last photo of a variety of species, including the common False eyelash weed Calliblepharis jubata. The tides and weather conditions are unfavourable the coming days but I hope to go snorkeling again end of the week!
After seeing so many Sand smelt (Atherina presbyter) (EDIT or potentially Herring….very difficult to make out position of fins) schools from the local slip and quay in Flushing this week (see previous post), I went for a snorkel on Castle Beach in Falmouth over the weekend. Lots more were to be found! Below two clips. I have hardly shot any videos with my camera, and it unfortunately shows. Shaky camera movement and I forgot I had the option of shooting at a higher frame rate too, doh! I clearly need more practice. Each school consisted of fish of the same size (the smallest fish were around 3 cm and the largest maybe 9 cm), but when chased by a hapless snorkeller some merged temporarily. If you look closely, you can see about one in a hundred fish have a little bite taken out of them, I did not see any predators though.
Last week I went for a little swim at the usual spot at Castle Beach. The viz was nowhere near as good as last month, but still OK. There are schools of sand eels and sand smelt and I even saw an eel. The contrast between growing brown seaweeds and withering red seaweeds has become even greater. Below you see some yellowed Harpoonweed and a ‘forest’ of Thong weed covered in epiphytes. As the light was a bit subdued, I focused on the most shallow area. The bare parts of the rock are covered with barnacles, dog whelks, sting winkles and limpets. The seaweeds are mainly Serrated wrack Fucus serratus, Sea lettuce Ulva, Grape pip weed Mastocarpus stellatus, some Ceramium and Laver Palmaria palmata, as well as Dumont’s tubular weed Dumontia contorta.
I have been diving three times last week but due to internet problems have not posted about them. I hope to do that in the coming days, but first wanted to blog about this mornings snorkel session in the shallow rock pools at Castle Beach in Falmouth, as I experienced the best viz (visibility) ever here. Apart from the stunning viz, I was very lucky with the fish: I spotted a Tompot blenny, Two-spot Gobies, Fifteen-spined stickleback, Rock goby, Pollack, Ballan-, Corkwing- and Goldsinny Wrasse and Sand eels (above and below). However, I mainly wanted to check what the seaweeds looked like, and things have definitely changed over the last month (see here).The Wireweed Sargassum muticum and Spaghetti (or Thong) weed Himanthalia elongata are thriving and at low tide hang over the surface creating ‘tunnels’. The Harpoonweed below is in decline, turning from pink to yellow-white (and the Bonnemaisonia is almost completely gone). The fronds of the False eyelash weed have turned from juicy and red-brown to wiry and yellow and the corraline algae are turning white. The Sea lettuce Ulva has died back and is covered in speckles (sporangia?). Some epiphytes are thriving, the very fuzzy brown Pylaiella littoralis covers kelp, a Ceramium species grows as pompoms on the Spaghettiweed. One pink and fuzzy species that is growing well I should have taken a closer look at because I am not sure what it is now (I will enquire at the Seaweeds of the NE Atlantic facebook group). The next species I think I can identify: Chipolataweed Scytosiphon lomentaria. The Bushy rainbow wrack Cystoseira tamariscifolia looks fuzzier and greyer than before. Although with less species and more subdued colours, the pools still look beautiful, and I hope the good visibility will last a bit longer!
Just a photo to show the beauty of Cornwall in spring! The snorkeling at the beach in Porthcurno (next to the marvellous Minack Theatre) was very pleasant this weekend, although there was not a lot to see: mainly white sand and wave-battered rocks covered in barnacles. I have simplified the “An Bollenessor” domain name and updated the Links page btw.
Another snorkeling post. Last weekend off Gylly Beach and without a wet suit (sea water temperature close to 20C now!). Plenty of fish about, with my first snorkel sightings of Sea bass Dicentrachus labrax and small groups of Red mullet Mullus surmeletus. Much to my surpise I also spotted a Cuttlefish Sepia officinalis half hiding between dead seaweed drifting in the shallows. It was not particularly scared and stayed put while I swam around it but after a while it let out a squirt of ink and moved on. Of course this was just when I did not bring my lumix camera, so the next day I went back and luckily it was in exactly the same spot:It did not end there. I next spotted a beautiful Blue jellyfish Cyanea lamarckii gently pulsating through the water column. Inbetween the tentacles three tiny fish were hiding, most probably juvenile Horse mackerel Trachurus trachurus:
