l have not made much progress sorting through recent seaweed pics but it is easy to post two recent photos that came out well. Above the Spiny starfish Marthasterias glacialis. This seastar can grow up to 70 cm across, but on the shore you generally do not find them much larger than 20 cm. It occurs from Northern Norway down to West Africa. Below a patch of Snakelocks anemones Anemonia viridis, probably originating via binary fission. The most common anemone in the rockpools here, around half are this tan colour, the other half is green with purple tips. No one knows why. (And interestingly, it is not the only anemone species that shows two colour variants, beadlets are red or green, plumose anemones white or orange). Although the water was 9C, with the sun on the white sand it looks pretty tropical to me, a clownfish would not have been out of place! (I took a photo of this same patch in March but that one was not nearly as good.)
This was the year I switched from my trusted Canon G16 compact camera (with wetlenses) to a mirrorless Olympus OM-D E-M5 II (with ‘actual’ lenses). Throwing money at things is not necessarily a guarantee for improvement, but it definitely helps! The shot above (from this post) was commended at the 2019 Falmouth Underwater Film Festival. This was made using the few times I went out with the mzuiko fisheye lens and is shot using natural light. (For some more natural light wide angle shots taken snorkelling on the north coast see this post.) I mostly used the mzuiko 60mm macrolens in combination with my strobe. The weather at the start of the year was so foul I initially used it abovewater during rockpooling. The shot below of a Flat periwinkle is quite simple but one of my favourites ‘topside’, together with the shot of the two Shore crabs: Below are some favourite underwater macro shots (the best pics I also post on instagram). Macrophotography I find easier, as the camera settings remain quite invariable (small aperture with a short shutterspeed because of the flash) and the composition is often (but definitely not always!) simpler compared to shots of say an entire rockpool. First some taken snorkeling in rockpools. The first is a Chink shell on Bushy rainbow wrack. The iridescent nature of the seaweeds means it is bright blue or purple viewed from one direction, but a dull brown from the other. If you get it right, it makes a very striking background and it is definitely a subject I want to explore more. After that, detail of the tip of a Spiny starfish, a European cowrie and a pill isopod. Below some macroshots taken while (shore)diving off Silver Steps in Falmouth. A Blackfaced blenny, a Leopardspotted goby and a Devonshire cupcoral. Many more photos of course if you scroll down. I have now also invested in a new strobe and new strobe arms. Having two strobes will allow me to take wide angle photos without depending on (dim) natural light, for instance whilst diving. My second strobe is manual so I can ramp up the strobe power if needed for macro too. I still struggle with positioning even a single strobe, so having two will be frustrating in the beginning I am sure. I am hopeful this new investment will pay off though. As for the blog, I have updated the links page. It is high time I post an update on the tank. I have not been diving much but hopefully next year I can collect some new species of anemones for it (and of course take photos, although the two activities are pretty much mutually exclusive). My new years resolution will be to get in the water more. I wish all blog readers a happy and healthy 2020!
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 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!
Santa Claus was very generous last year and I am now the proud owner of an Olympus OM-D E-M5 Mark II mirrorless camera! A big step up from my Canon Powershot G16 compact camera (which I still find a great little camera btw). Apart from a better sensor, greater dynamic range, more pixels etc, the main reason for going for a so-called micro four thirds camera was that I can use separate lenses. By that I mean lenses that actually go on the camera rather than wetlenses that are attached to the camera housing. The wetlens approach has the problem that air bubbles can form on three surfaces rather than one, and also, water seeps out from between the lens and housing every time you lift it out of the water (which I tend to do a lot in rockpools less than a meter deep). I first thought of going for an SLR, but these are much more expensive (the housings at least), require looking through a viewfinder which seems annoying to me and also they are considerably bigger, which is also not handy in rock pools. Luckily I learned that mirrorless cameras also existed! I bought an M.ZUIKO 60mm f/2.8 Macro Lens as well. I have not been in the water yet, as the weather has been grim, but took the camera out for some above-water rock pooling last weekend. The first day I did not take the separate flash, which demonstrates my ignorance (to maximize the depth of field, a small aperture is needed which lets in little light, resulting in long shutter times and high ISO). The photos were not great, but the next day with flash it went a lot better. Above a Broad-clawed porcelain crab Porcellana platycheles and a Long-clawed porcelain crab Pisidia longicornis. Next time I will bring a ruler to show exactly how tiny these crabs can be (these are juveniles).
Above a flat worm (check the eyespots!) and a Thick top shell Phorcus lineatus. A main problem is that all subjects are covered with a film of water, resulting in glistening highlights when using the flash. Another issue is the shallow depth of field. The next time I might try to do some photo bracketing/stacking, merging images of a different focal depth (I need a tripod for this). The great thing is that there is no shortage of subjects: turning over a single rock can reveal multiple species each of echinoderms, molluscs, crustaceans, bryozoans, worms, flat worms etc. Below a selection of chitons, I have not had time to check out which species; there are not that many here but they are tricky to identify from photographs. I will check Ian Smiths fantastic photo resources on flickr to do so.
