It has been a while since exploring the rockpools, as the weather has been pretty horrific. However, I had a good go last week and this weekend. Although quite bleak, there was no wind and no rain. The water is getting down to 11 degrees probably (I have not measured it), so pretty chilly. There are quite some solarpowered seaslugs Elysia viridis on the Codium seaweed but I did not manage to get any good photos. In fact, I am still struggling a lot just getting the strobe to properly light up what I am aiming to photograph. A bit frustrating but that is why I keep practicing. Above a pill isopod, probably Cymodoce truncata (with the fringing hair on the rear uropods indicating it is a male). Below, a tiny Gem anemone Aulactinia verrucosa. There are a lot of small Daisy anemones Cereus pedunculatus amidst the Coral weed, they look brownish but when you zoom in there is some blue as well. Finally, a Netted dogwhelk Tritia reticulata, which are very common and active in the rockpools. Cold but always nice to be in the water. Luckily I emerged right on time when I saw my Sainsbury’s bag with glasses, car keys and phone drifting away due to the incoming tide!
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!
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.
