Photography during my last snorkel was a bit frustrating as I could not get my strobes to work. Luckily I was saved by a subject that did not require any extra light: beautiful translucent crystal jellies slowly pulsating near the surface. Crystal jellyfish are not true jellyfish (these belong in the Class Scyphozoa), but hydromedusae (Class Hydrozoa) which have a polyp stage in their lifecycle that bud of these sexual medusae. They are difficult to identify to species level so I keep it to Aequorea sp. I saw a few, around 10 cm in diameter, and had fun diving under them and get them in front of the afternoon sun.
I had not been in the water for many weeks due to bad weather, work and laziness, but as the sun was shining last Tuesday and there were indications from social media that the plankton bloom had gone, I went back in for a snorkel. The water has warmed up, although the viz was not as good as I had hoped. I swam a bit further than my usual shallow rockpools to explore the kelp forest. Pollack, wrasse, mullet and sandeels swam about. I noticed a line with crabpots starting very close to shore, something I had not seen before. Unlucky spider crabs and some lobsters could be seen in the pots. Below a Spider Crab that was still free….
After exploring the slightly deeper waters I went back into the pools where the viz actually cleared up a bit. Seaweed-wise, things have deteriorated a bit compared to early spring, but it was a very nice swim around all the same!
A quick posts of some wide angle photos I took at the start of this month. The seaweeds were just past their prime but still looked nice and the viz was really good. It was great to slowly swim through the water in my usual spot between the rockpools ‘proper’ and the kelp forest. Just like swimming in a giant aquarium! Not too many fish or other animals to be seen. I always manage to suprise one big resident Ballan Wrasse. Other than that there were tiny Pollack and some Two-Spot Gobies. I have not been in the water since because the weather (wind) has not been great; maybe next week! Btw, I am also on instagram: @an_bollenessor.
Just a very quick post: went for a snorkel today as the sun was shining; there was some wind so the viz was not the best. Snapped a lot of ‘6’s but I liked the green Ulva lactuca (sea lettuce) and the red Sphaerococcus coronopifolius (berry wart cress). Both are plants (‘Plantae’) and not related to the brown kelp in the background (which is more closely related to potato blight!).
It has been a wile since I last posted. This winter was long and dreary, the sea choppy and grey. I managed to do some rock pooling, and took a bunch of pictures, which I probably should have posted… The good news is that a mishap with my camera housing last year resulted in Olympus giving me a new model housing + a new model camera to fit (OMD EM1 mark 2) AND a new dome, lucky me! Regular readers of this blog know I get very excited in March, as this is when the seaweeds look at their best. This week the tides were low and the wind conditions favourable (the sun was not always out unfortunately), so I made sure to go in the water every day. The water is cold (9C), especially after being in for 2 hours, but it is all worth it. The seaweed growth was lush, with species literally growing on top of each other. I tried to shoot with strobes, but this proved too difficult and switched to natural light. Keeping ISO at 200, I aimed to lower shutter speed to 1/30, managing an F stop of between 5 and 8, depending on cloud cover. I now get the hang of that, but it is difficult to keep photos well-exposed, with enough depth of field and maintain sharpness. Below some examples. I am lazy and will not add seaweed names (but see the Seaweed Gallery page at the top if you are interested). When the tides are low again at the end of next week I hope to go out again!
The jellyfish are upon us again. Slow and photogenic, I had to go out yesterday in Falmouth Bay to try out two strobes with my fisheye lens for the first time. Unfortunately, the sea is like pea soup at the moment. The wide angle allows for a close focus (getting right up to the subject) so that minimises the problem of low viz, but there still is a problem with backscatter (especially when the strobes are not positioned the right way). Anyway, I had a lot of fun practicing. Although they did not come out as crisp as I hoped, cropping, decreasing highlights and increasing contrast and clarity, made them look acceptable. I encountered a few Compass Jellyfish Chrysaora hysoscella, one with a small Gadoid fish in tow (above). A bit more common were the Crystal Jellies (in the Class Hydrozoa and so not ‘proper’ jellyfish as in the Class Scyphozoa) pictured below. They are in the Aequorea genus but I am not sure of the exact species. The Barrel- and Blue Jellyfish will soon follow, giving more opportunity to practice wide angle strobe photography.
A day without wind last Thursday and so time for a look at the seaweeds. As expected, the pinks, reds and purples have made way for browns, yellows and greens. The water was a bit cloudy but with the wide angle lens you can get close up minimising the effetc of the bad viz. Wrasse were tending to nests and tiny pollock swam around but otherwise I could not spot not many animals; the exception was a big spider crab who was as startled as me. Above the common species Thin Sausage Weed Asperococcus fistulosus. Not the most beautiful species but let’s say it looks interesting. To my horror, I discovered that my favourite seaweed Bushy Rainbow Wrack has changed genus and is now called Carpodesmia tamariscifolia instead of Cystoseira tamariscifolia. I hate name changes in general but this just an ugly name! Two photos of this species below as well as one of Bushy Berry Wrack Cystoseira baccata which also has moved genus and is now Treptacantha baccata… After that a floating piece of Desmarest’s Flattened Weed Desmarestia ligulata and some Pale Patch Laver Pyropia leucostica.
A while back I thought it might be an idea to experiment with flash photography. Using one flashgun (strobe) I set out in my usual spot. I should have tried this a lot earlier! Although supershallow water has enough light to do without flash, a main problem (for me at least) is to balance harsh white sunlight (from above and from reflections from the white sand below) with the darker subject. By illuminating the subject, this effect evens out. I took probably almost a hundred photos of the Bushy Rainbow Wrack above and this one came out alright! Apart from the Thong Weed framing it, I like the row of Thong Weed ‘buttons’ in the foreground. I held the strobe in my hand for this one, and I used my older strobe, as my newerand more expensive manual one just not fires reliably for some reason (still trying to find out what is going wrong). Below some more strobe experiments. I really hope diving will be allowed soon so I can play around more with the wide angle lens and two strobes.
Just three pics of the same shark egg case (‘mermaid’s purse) laid by a Nursehound (Scyliorhinus stellaris), also known as Large-spotted dogfish, Greater spotted dogfish or Bull huss. My camera was only five centimetres away from it (this technique is called ‘close focus wide angle‘). Mostly attached to perennial and tough Bushy rainbow wrack (Cystoseira tamariscifolia).
Some more March shots of seaweeds but this time taken in a large, very shallow pool a bit higher up on the shore. It is dominated by Slender-beaded coral weed Jania rubens together with some other favourites (but many other species, such as Palmaria, Polyides or Furcellaria are missing this far up shore). I have added the names to some species, as Francis Bunker (one of the authors of the Seasearch guide to the Seaweeds of Britian and Ireland) had done previously on the Seaweeds of the NE Atlantic facebook page for another photo (see this post). Nice to be able to get so many species into one shot. Next an over-under (well, a bit) shots for another general impression (see the shadow of my camera), some Bushy rainbow wrack Cystoseira tamariscifolia, False eyelash weed Calliblepharis jubata surrounded by other species and a tiny fluffy red seaweed (do not know which species) that has found a foothold on the bare bedrock. The photos are not as sharp as I wished unfortunately. I have another batch on the computer that turned out better luckily, will post these soon!
