I have been out twice this week with the Canon G16 with the hope of snapping a few good photos (out of the hundreds I take). It was trickier than usual, in part because the viz was not great but also because I am making a bit less progress I feel. Investing in an expensive DSLR + housing will get me further but I do not know if it will be worth the money. However, I still have a lot to do when when it comes to mastering the principles of photography, especially getting to grips with manual settings. In this post I will highlight some of the ‘issues’ am facing; who knows I will be lucky and get some feedback via the blog (and instagram), sharing is caring! As usual, I focussed on the seaweed diversity, although at this time of year it is not the best looking. The photo above is nothing special (the seaweed looks a bit straggly) but I like the blue background. It is interesting the wide diversity of seaweed species on the Red rags in the photo below and I like the contrast of the green sea lettice versus the brown Bushy berry wreck in the second photo but both pics are a bit meh. A main difficulty is that many times the sand (orthe bleached coral weed) contrast with the subject of the photo resulting in excess highlights. I try to counteract this by reducing F-stops (resulting in an overall darker picture) and reduce highlights during post-processing. @chris_exploring recommended to choose overcast rather than sunny days which is probably the best approach (and I will have plenty of opportunities to test this the coming months!) The first pic below of a Two-spotted goby is OK but I could not get quite close enough. The second photo is of course out of focus but I included it anyway to show that some of these photos have great potential. It inspired my own photography rule (the ‘Vos Index’): the beauty of the subject (on a 1-10 scale) times the difficulty of a shot (on a 1-10 scale). We are all trying to score a 100: a perfect capture of a beautiful organism. I am stuck with mediocre captures of beautiful things. Sometimes I get a very good capture but then mostly it is of something not-so beautiful. I shoot JPEG + RAW, which is a bit of a pain as I do not want to clog my hard drive and reviewing and deleting JPEGs and then having to filter for names to delete the associated RAW files is annoying. I actually keep few RAW files because very few photos are worthy of any advanced Photoshop editing, and also the standard Windows photo editing software is not half bad. For example see the photo below of whitebait (impossible to tell if it is herring, sprat or pilchard). It is very low contrast and bluish; by reducing highlights, increasing ‘clarity’ and a bit of cropping the image is completely transformed (although still relatively unusable as the resolution is quite bad). Finally macro. I just cannot seem to get my strobe to work which is annoying so the pics below are all ambient light. I need to up my game with this as there are so many cool subjects around to shoot if you take time to look. Below some tiny (3-4 mm) snails Rissoa parva. I wanted to zoom in more but was unable to unfortunately. Next a much bigger (2 cm) Netted dog whelk Tritia reticulata (sigh, I knew this as Nassarius reticulatus, and Hinia reticulata but the name has changed again). Next, a baby (3 cm) Tompot blenny Parablennius gattorugine which are one of the easiest fish I know to photograph, not very shy! Finally another challenge to photograph, a mermaids purse (egg case) of a Nursehound Scyliorhinus stellaris shark with a tiny (2-3 cm) embryo visible. I had a little light with me that I used to illuminate it from the back but this could be improved upon as well!
I usually head down straight to the lowest reaches of the shore when rock pooling, but when there is a neap tide and a lot of inshore wind as there was this weekend, you have to make do with turning rocks higher up the shore. Although biodiversity is lower, there are some species that are only found there (see for instance this recent post) and so it is actually nice to have a look there for a change. The very first rock turned over actually had a couple of interesting inhabitants underneath it. Another lifer, the tiny gastropod mollusc Onoba semicostata (surrounded by a couple of even tinier Rissoa parva), very quickly identified by members from the British Marine Mollusca facebook group:
The same rock had a number of the tiny (< 1 cm) Cushion star species Asterina phylactica on it as well. It is prettier than the common Cushion star Asterina gibbosa (one of my favourite aquarium species), but perhaps a bit too small to be an option for the tank.
One other beautiful species, the colonial tunicate Botryllus schlosseri, this is a nice blue/purple one:
The tides were good this weekend and so we went out to Gylly (Gyllyngvase) Beach in Falmouth, specifically the rocks to the west of the beach (I normally go to Castle Beach to the east):
Although the tide was quite low, no special sublittoral species were encountered, but everything time you go out you still see something new. For instance, a newly moulted Furrowed crab, Xantho incisus pink and soft next to its old brown carapace:
There were very many small Blue-rayed limpets Helcion pellucidum (see also here) on the kelp:
