It is the time of year where the rock pools look less attractive (for an example see this old post) and jellyfish appear in the sea beyond. As they are pretty and slow moving, they make for excellent subjects and so I have ventured out over the kelp recently to look for them. I now have a reliable INON D-200 strobe (actually I have two such strobes, it is just that the second arrived 6 weeks ago but not its fibre optic cable…) which makes a huge difference in the types of shots you can take. Photos taken using natural light only can be pretty (see for example here for previous attempts) but a strobe just opens a whole new range of possibilities. I was quite pleased with myself with the shot above of a Compass Jellyfish that seems to float in outer space. Here, the strobe lights up the jelly (which is really close in front of the camera) but it cannot light the ocean behind. Using a fast shutter speed, the ambient light (that would make the water blue) is not let into the camera, resulting in a black background. An exception is the bright sky, which is visible in Snell’s Window, and which looks a bit like a planet against the black background. Of course, even with using a strobe you can choose to let in ambient light, leading to more conventional shots such as the one below (however the jellyfish is a bit further away and not very nicely lit up by the strobe):
By pointing the camera downwards and getting rid of much of the sunlight, the fast shutter speed black background effect is even stronger, even on a sunny day. An example is the Moon Jellyfish below. Btw, I have touched these photos up with the generic Windows photoviewer (a poor man’s Adobe Lightroom) whch performs quite well. It is however tricky to get rid of some of the backscatter (particles in the water that light up because the strobe is incorrectly positioned, illuminating not just the subject but also the water in between subject and lens). This effect can be seen above the jelly in the second photo even after editing in Windows Photo:
It is great fun to practice photography with these jellies. In principle one strobe is enough (and many pro photographers recommend to try shooting with a single strobe). However, there are situations where two strobes are clearly better, namely when a subject needs to be lit up from two sides. The photo below was taken with the camera turned 90 degrees with the strobe to the left side (notice the remaining backscatter after using the clone stamp tools in Windows Photo). Having had another strobe to the right would have avoided the shadows (but probably have added backscatter!):
Some more shots below. The visibility has been poor lately but I hope to be able to practice some more over the weekend.
The sun is shining (most days) and the water has warmed up, so ideal conditions for a bit of snorkeling. I have been out at my usual spot in Falmouth (rockpools and kelp forest) and my local beach in Flushing (seagrass) (and yes, I really count myself lucky every time that l live here!). The last couple of times I have brought my son along, as he is now old enough (nine). He is a nature freak just like his dad, actually probably more so! I need to get him fins and a weight belt soon, but he has been doing fine in the water already.
The photos above and below illustrate the state of the rock pools at the moment: quite brownish with the Sargassum and Himanthalia growing everywhere. The red, pink and purple species have largely disappeared (apart from Harpoon weed) and there is quite a bit of green Ulva growing. The water teems with juvenile pollack in the rock pools and schools of sand eels a bit further out. Diving over sandy patches, you can see the latter species shooting out of the sand en masse. It is crazy how such a silvery pelagic fish can also burrow in the sand. I guess it does take its toll, as there are quite some dead ones to be seen too.
The Flushing snorkel site is very different, no (deep) rockpools, only a little bit of kelp but with a very healthy patch of seagrass. No catsharks or thornback rays when we went in, just the odd small sea bass. There are many small Snakelocks anemones on the seagrass. I used to think that it was mostly the purple form that did this but I now noticed that most were the green variety, so the morphs do not seem to differ in this respect after all. One anemone had ‘caught’ a crystal jellyfish (an Aequorea medusa). Not sure if it was in the process of being digested or just ‘stuck’.
I have played around with my new INON strobe, which works a lot better than my old strobe. I have ordered a second one for Wide Angle photos too….(as you can see there is quite some backscatter in the pic of the Shore Crab above). I will need to get back to some shore diving to make optimal use of two strobes, as I am too lousy a freediver to get the lighting and exposure right in one breath!
Some more jellies, this time the Compass Jellyfish Chrysaora hysoscella. These are currently the most common jellyfish here in Falmouth, with blue jellies and moon jellies also spotted (the Crystal Jellies, see below, seem to have disappeared). These photos were made without a strobe (my struggle with them continues…) which would have made them much better. As it stands, I have relied heavily on the standard Windows Photo editor to reduce the green hue and get rid of some of the highlights. I might give the old strobes a go next time I go in!
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.
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.
Facebook/instagram and even news websites have been awash with Barrel jellyfish photos and videos the last week and so I had to get a piece of the action! I had seen these gentle giants in previous years but had not tried to take any photos in earnest. I snorkelled out from the beach in Falmouth and after 200 meters or so I sure enough found three or four (they occasionally came close to each other but there of course was zero interaction). Barrel jellyfish Rhizostoma pulmo can in rare cases have a bell 90 cm wide but these were smaller, maybe 90 cm in length. I dove to take shots from below again and again: good exercise! I learner to hold my breath so the shot would not be ruined by air bubbles. I tried some over-unders but the shore was far away and so ended up only being a sliver, tricky!I tried some downward shots as well, which were much more gloomy. I saw a lone Blue jellyfish and a couple of Compass Jellyfish Chrysaora hysoscella. They are much smaller and have longer tentacles that unlike the Barrel jellyfish can sting (but not badly). Jellyfish are a great subject, beautiful and not rapidly swimming off! I hope to go back soon and try some more shots. (I will have to make sure to wipe the dome port occasionally as I had to spot-fix quite a bit).
Rumours had it that the viz was great at the North Coast last weekend, and as it was pretty bad at the south Coast, I found some time to drive up to St. Agnes (buying new fins on the way) with the fisheye lens+dome. I was not disappointed: look at that blue sea! The water was clear, the sand was white and the seaweeds were waving on the rock faces. I saw flounder, mullet (thicklipped and red), seabass, sand eels, corkwing wrasse, sand smelt and most interestingly: weeverfish. Swimming above the sand with yellow fins and burying themselves so only the eyes are visible. I saw one half a meter deep on the beach, so it is advisable to wear surfshoes (see here). Unfortunately I could not get a good photo. I tried to take photos with the strobe but that did not really work so all photos here are natural light, trading off ISO, shutterspeed and depth of field to get the right exposure. There were Blue jellyfish around (small, 2-4 inches), and I tried to shoot them over-under but that was a bit too ambitious. Some easier shots instead. I hope to find some big Barrel jellyfish in the coming weeks, as they will be a lot easier to shoot!As the fish proved a bit too fast, and the over-unders a bit too difficult, I tried to take some shots of seaweeds instead. Although I mainly knew it from more sheltered locations, there was quite a bit of Mermaid’s tresses Chorda filum on this exposed coast. There was a lot of discoid forkweek Polyides rotundus on the sand but also on the rocks, and often covered in Falkenbergia. Other species that were abundant were Hairy sandweed Cladostephus spongiosus and Desmarestia ligulata. Hope to return soon!
The weather today was pretty bad, but it was still very nice to go for a quick stroll on the beach; we chose a new destination: Gunwalloe near Helston. The beach and cliffs here are more reminiscent of some of the North Coast spots, quite barren. At the moment, Facebook and Instagram are overflowing with pretty pictures of washed up Portuguese man o’ wars (or Portuguese men o’ war?) in Cornwall, but we only saw two small shrivelled up ones (at Holywell Beach) so far. It was therefore great to see ten or so on the high tide strand line at Dollar Cove and Gunwalloe Church Cove. The smaller ones measured only five cm or so, with the largest one close to 20 cm (the size refers to the pasty-shaped, gas-filled float or pneumatophore). Unlike true jellyfish, which can move by contracting muscles around their bell, the Portuguese man o’ War (Physalia physalis) just sails. More amazingly, they actually are not individuals but colonies comprised of different, specialized individuals (it is getting late writing this, so I will lazily refer to Wikipedia). Stunning colours and truly great finds!
