Macro Shenanigans

I had my first two outings trying the the mzuiko 66mm macrolens with strobe this week. I managed to make some OK pics more due to luck than wisdom! It is actually not that difficult to find interesting subjects, but getting finding them back in the zoom finder is quite tricky (I usually point at a subject with my finger and then try to find a big white blob back when looking at my camera, then hoping to encounter the animal somehwre nearby). I managed to find a Least chink shell Lacuna parva spent on a Rainbow wrack Cystoseira tamariscifolia plant and spent 30 minutes looking at it.  Although there is not much definition on this tiny (5mm) all-white organism, the blue background looks great. I will definitely go back to specifically look for (slightly bigger) things on Rainbow wrack! (The iridescence of this seaweed means that if the (strobe)light hits it at a different angle it is a dull brown rather than a deep blue or purple.) To give an idea of how tiny some things are see the photo above of the shell-less mollusc Runcina coronata (this is an ophistobranch, it does not have gills on its back as do nudibranchs), it was really, really tiny! This photo is nice for ID purposes but I do not expect I can take good photos of species this small (you reallly need an additional macro wetlens for that). I only later noticed the even smaller mollusc Flat skenea Skeneopsis planorbis next to it. (I identified this species using the excellent new Essential Guide to Rockpooling by Julie Hatcher and Steve Trewhella by the way, highly recommended!). I also noticed I need to clean my finger nails! (More tiny molluscs were present, including Eatonina fulgida.) Next, the mollusc Tritia reticulata (which I knew under the names Nassarius reticulatus or Hinia reticulata….) or Netted dog whelk in common parlance. These are very active and fun animals. The macrolens really brings out how battered and overgrown the shell is and the beady little eyes also stand out. A little hermit crab posed nicely as well. Another difficulty is working the strobe. Unlike the ‘normal’ ambient light photography I am used to, the image after clicking is different from that seen through the viewfinder so it is trial by error. Often the subject is not properly exposed. Also, floating particles cause backscatter. Perhaps I should try a snoot to minimise this effect, which can ruin an otherwise decent (in focus) photo, like this one of a Stalked jellyfish Haliclystus octoradiatus which are common at the moment. (Notice the tiny molluscs on the seaweed in the background.)Finally some random pics: a Light bulb seasquirt Clavelina lepadiformis, two colonial seasquirts (a Morchellium argus and a Didemnid species) and a Bryozoan (it is late and I have not looked up the species). A whole new world opens up if you look at the tiniest denizens of rock pools, all complex, colourful and fascinating!
