more macro rockpooling

Another quick, brisk trip to the rocky shore in my village of Flushing today to practice my macro photography with the 60mm lens. I used the highest F-stop, varied the output of the flash and let the camera decide the shutterspeed and ISO. I did not find anything too special, but the very common organisms are just as pretty as the rarer species. Above and below juveniles of the Flat topshell Gibbula umbilicalis and the Grey topshell Gibbula cineraria on pink encrusting algae. Still not quite used to not having optical zoom as with my old Canon Powershot but quite happy with the shots, especially as all were hand-held. As I am lazy, these are JPEGs with some  tweaking using Windows photoviewer.

Below a Black-footed limpet Patella depressa, a more ‘atmospheric’ shot of a periwinkle, might be the ‘normal’ Littorina littorea but not 100% sure, and a baby Edible crab Cancer pagurus. Really looking forward to go into the water again, but not only is it still cold and grey, it is very windy and choppy so bad viz. Probably another rockpooling post next weekend!

First attempts at macro photography

I recently posted my first photos taken with the nauticam CMC macro wetlens using stalked jellyfish as a subject. I since lost my lens, which I in large part blame on the bad fit of the adapter with which it is attached to the housing. The best thing in these cases is not to agonize over it too much, order a new one straight away and keep going, so that is what I did (also I am now a bit more careful of course). Here some more photos of macro subjects. Above a very easy subject as it is very common this time of year and also it does not move….Paddle worm egg capsules (probably Eulalia viridis). The individual eggs can be just made out in the gelatinous blob. Below, one of the more common nudibranch species Polycera quadrilineata. Nudibranchs come in all kinds of stunning colour variations and are very species rich and so are a favourite of macro photographers (see this old post hunting for them with David Fenwick in Newlyn, and check out the NE Atlantic Nudibranch facebook page for lots of eye candy). Tricky with the narrow depth of field to get the whole animal in focus. Mysid shrimp are quite common and beautiful little animals hovering about in small groups. They need dissection to determine which species it is, but this might be Leptomysis lingvura (around 10 mm). Finally, the colonial star Ascidian Botryllus schlosseri; these form colonies (‘systems’) where zooids have individual inhalant openings and a shared exhalant opening. They are common, sessile, flat, and come in a range of colours so they make ideal subjects for a beginning macro photographer.  Not only that, apart from fish they are our closest relatives in rock pools, which is most obvious in the tadpole-like larvae which have a dorsal notochord (a cartilage rod functioning as a backbone). I hope to devote a post to them later in the year.
