Macro Musings

Foul weather in Cornwall at the moment (it is November, so no surprise there!). Not tempted to go in the water but still wanted to take photos, so I spent some time on the foreshore of my village Flushing looking at Flat Periwinkles (Littorina obtusata). This species is very common, and the only snail that actively crawls about above the waterline. The trouble with macro photography is that with a small aperture, the depth of field is large and everything is in focus, but this includes the usually cluttered background that takes away from the subject. With a large aperture, it is possible to get an aesthetically pleasing, soft focus bokeh background, but the depth of field is much smaller, and too much of the subject is blurry (see the pic on the right). I tried my hand at focus stacking, in which the camera takes a bunch of photos each with a different part of the subject in focus, and then merges them so the depth of field is greater (whilst still having the out-of-focus background). This proved too difficult with a handheld camera (especially on my knees in seaweed). I therefore reverted to ‘normal’ manual photography and it was fun to practice. However, I did not manage to improve on my best Flat Periwinkle photo I took when I first got my Olympus….

Miscellaneous Macro

I have not posted a lot this year; in part just because I have not been out as much as I hoped I would, and in part because I had some technical difficulties (I had to sent back a malfunctioning strobe and am also having snoot troubles). As a result I have not gone scuba diving and did not see much of the rock pools either. I managed to take some macro shots over summer though that are worth a quick post. Above a Cushion Star Asterina gibbosa on a colony of the star ascidian Botryllus schlosseri. Below one of my favourite little molluscs, the beautifully patterned White tortoiseshell limpet Tectura virginea. Another tiny mollusc, is the Needle Whelk Bittium reticulatum. The Variegated Scallop Chlamys varia is also common (under rocks) and can be nicely patterned when they are small. Finally some other tiny critters: the Flatworm Leptoplana tremellaris (I like their beady little eyes) and the Bryozoan Disporella hispida.

new strobe

Long time no post! Due to a combination of not-so-good weather and work I have not been in the water much the last few months. I attempted some seaweed photography but most times the viz was bad; the one time the conditions were great, somehow all my photos turned out to be a bit meh and I could not be bothered to post them. (For some older shots on seaweed diversity see here, and many older posts as well.) Anyhow, my exciting news is that I finally bought a new strobe (an INON D-200 for those who are interested) because my old Sea&Sea strobes just proved to be too temperamental. Something I should have done a long time ago, but the thrifty Dutchman in me just never pulled the trigger. I have now taken it out twice this weekend and it works like a charm! Now I just need to practice, as it is actually still very hard to go from an OK photo to a truly good pic. Above a shot of a baby urchin Psammechinus miliaris. The true stars of the weekend however were nudibranchs.

A very special find (shown to me by fellow rockpool photography enthusiasts Martin and Greg) were two Goby egg-eating seaslugs Calma gobioophaga. This tiny species can only be found on the goby eggs it eats. With such a ‘niche niche’ and with very good camouflage it is no wonder that reports of this species are rare. A fun fact: its protein-rich diet means it does not have to poo and it therefore does not have an anus…The rock with the eggs and nudis was very shallow and so it was a challenge to get the port of the camera housing under water. Luckily Greg assisted with pointing out the nudi and holding my strobe in place. Freshly hatched goby fry could be seen hovering above the eggs (the fact that a predator was munching through their brothers and sisters might have triggered some of the hatching). The cerata (the fleshy lobes on the nudi’s back) seem to have two goby eyes in them to make them better blend in!

Finally, two other nudibranch species, neither very colourful. Both are predators of anemones: first the largish Grey sea slug Aeolidia papillosa and second the smaller species Aeolidiella alderi. Both adequate shots but I need to practice to make them truly good. I will probably buy a second INON strobe so I can practice wide angle shots as well when diving. I hope to go out a lot more during summer and will make sure to post here about my finds and progress!

Macro

The weather has been horrible lately, with three storms coming in straight after each other. On the upside this means that there is good potential for beachcombing, but alas, the one beach on the North Coast we checked was as clean as a whistle, just sand! So here are some photos from a few weeks back when the weather was good better. On top a Spotted Kaleidoscope Jellyfish (Haliclystus octoradiatus), about 15 mm across, on some Irish Moss seaweed. Please see this site for more information on these beauties; there are several species in our rockpools, but you have to develop a bit of an eye for them! Some other pics below: Blue-rayed Limpets (Patella pellucida) on kelp and a Thicklipped Dogwhelk (Tritia incrassata (when I was young Nassarius incrassatus…). Still need a lot of practice with the strobe, these shots I was very happy with, but most were way off the mark somehow. Looking forward to spring!

Candelabrum cocksii

It was a nice day and a good low tide last Wednesday and so I decided to go for a snorkel; I was glad I did! Last year, I had been trying to take photos of this weird little animal, Candelabrum cocksii, but failed miserably, this time it worked (although it could be improved). It is a hydrozoan that was first described in Victorian times on the exact beach I always go snorkelling here in Falmouth. It is tiny (see last pic) and lives underneath rocks, so it goes mostly unnoticed (and therefore does not have a common name). To take this photo, I had to do some ‘underwater rockpooling, turning over a rock to find them. I am not sure what the deal is with these guys; I know the white bulbous structures at the bottom are reproductive structures, and the reddish bit at the top is for feeding (this bit can be stretched out quite a lot). It is colonial just like the Portuguese Man O’War. Please correct me if I am wrong hydrozoan experts! Shout out to David Fenwick and his ID site aphotomarine.com, which I highly recommend.

Other notable finds were stalked jellyfish Calvadosia cruxmelitensis and my very first Wentletrap (which is a Dutch word: wenteltrap=spiral staircase) Epitonium clathrus. As I had my macrolens on the camera I could not shoot any general impressions but the pools started to look beautiful again. The big Wireweed and Thing weed plants were all gone (new ones emerging) and the red seaweeds (Sphaerococcus, Plocamium, Chylocladia) were already quite big.

It was great to be back in the water today and it is my New Year’s resolution to spend a lot more time underwater than I did in 2021! Who knows I will even learn how to use strobes. A happy 2022 to all blog readers!

Spotted Kaleidoscope Jellyfish

Two days after the last post I went back to my usual spot, fisheyelens on the camera. After a little recce it was obvious that the water was too milky, so I went back to the car and changed to the macrolens. It was overcast and the water was chilly. I’d seen some stalked jellyfish (see this great resource stauromedusae UK) the last time. Of course, when you are specifically looking for something you don’t find it, but in the end I noticed a Spotted kaleidoscope jellyfish Haliclystus octoradiatus, the most common species around here. I still struggle with my strobe, so all photos were riddled with backscatter. I could remove most of that in Photoshop luckily, but it is frustrating, especially as I had a run diving last year when I had no such issues at all. I encountered a 15 cm or so Longspined scorpion fish Taurulus bubalis as well. I cropped the shot and could put some colour back in using Windows Photos. Hope to go back over the weekend.

Olympus Photos 2019

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!

Macro Practice VI

The tide was bad (i.e. low and too early to catch it on time), the water was cold and it was very windy but it was good to go for a dip this morning. I now have a different strobe arm which makes it easier to position my strobe, which has often been tricky. Time for some macro practice. The photos are not that special but I hope interesting enough for you blog readers! Above a Peacock worm Sabella pavonina sticking out of an abandoned piddock hole. Below a common Hermit crab Pagurus bernhardus, a Grey chiton Lepidochitona cinerea, a very small Dahlia anemone Urticina felina (note the warty, adhesive column) and some Daisy anemones Cereus pedunculatus.

Rockpooling in Flushing

Some pics from today at Flushing Beach. Above, a pair of Green shore crabs Carcinus maenas, below two Furrowed crabs Xantho hydrophilus. (I probably should have gone for a whole crab series, as I saw several other common species…) Instead I took loads of random photos, of things that were 150 mm to things that were only 5 mm, with varying success. For instance of a Painted Topshell Calliostoma zizyphinum on the invasive Bryozoan Watersipora subatra. Also the underside of the urchin Psammechinus miliaris, showing its mouth (Aristotle’s Lantern). Photobombing top left is the commensal worm Flabelligera affinis (which I noticed as well the last time I took a version of this picture). Bit random but it was fun practicing. It actually is more difficult to take photos abovewater compared to underwater due to the glistening and the awkward position kneeling on wet gravel/rocks. Next time I might try a tripod (ideally remote flash would be used but I do not think I am going to invest in that). Btw, if you are on instagram, I also post pics as @an_bollenessor.

Silver Steps Diving IV

A solo dive early evening at the Silver Steps site. It was a couple of weeks I last went, and this time it was already dusk when I entered the water. My intention was to find cup corals and other small creatures growing on rock overhangs below the kelp line. The viz was good and sure enough I found what I was looking for: Devonshire cup coral Caryophyllia smithii, a solitary stony coral which is relatively common. They are very beautiful and the right size for the macro lens. I will definitely go after them again. Other finds were a golfball sponge Tethya aurantium, a baby Longspined seascorpion (this shot had potential, but it swam away unfortunately), a tunicate and a Painted topshell (very common). At the end of the dive unfortunately it was getting too dark to find objects or too properly focus; I need to sort out a dive light!
