A few photographic effects for your perusal..and Storm Angus

Well, hello from Storm Angus ravaged Wales!

Kind of storm ravaged. Okay…not at all, just the tail end. We didn’t get this all half as bad as the south of England, if you wish to, you can read about the main bits in the Daily Telegraph.

Cue the normal film (courtesy of YouTube on this occasion) on the evening news of people who should know an awful lot better canoeing in the street, standing perilously close to waves crashing onto beaches, generally being a teeny bit dull or driving into water that is far too deep.

Honestly, if I knew that Newhaven and Brighton and similar areas were going to get this much coverage in the years after I moved to Wales, I wouldn’t have bothered coming! Only kidding. Still, at least I stayed relatively dry. The wind was perishing cold though, that was what bothered me the most as I don’t have an awful lot of meat on me. This is due to get less after Christmas too as I will be embarking on a proper 12 week training regime to do a further sportive bike ride of 100 km (60 miles) in aid of charity. I was looking at the handy downloadable training timetable and I am struggling to think of routes that fulfil the length of time or distance needed and also go in a loop to assist me in not transporting the bike around the county in a car that is too small for it. I’m sure it’ll be fine.

However, let us not be bothered by my good deeds. You read this for my wit and pictures don’t you? I like to think so, but I could be having a one-way conversation with the vast internet. So let us begin.

Iridescence. Difficult to spell, even more difficult to spot. More difficult to photograph than both of those things. I think I have posted images on here with some “mother of pearl” effects in some winter clouds but these are not to be confused with the proper nacreous or polar stratospheric clouds.

In this instance, you have to look very carefully at the tips of the dead clematis flowerhead I took a picture of a while back…

I never noticed the fact there was some iridescence in this image when I took it to be honest but looking at Mr Wikipedia…thanks be to Wikipedia…it says that the effect is generally created by microstructures that interfere with light, which figures as these flowers are very intricate and the flash fired in this image.

On to a more familiar subject, the sky, but a more unusual effect in the clouds than usual. You may remember a while back that I pointed out some oh-so-catchy Kelvin-Helmholtz instability in clouds at sunset that caused what look like cresting waves? In a nutshell, it’s the interaction of two fluids of varying density such as the wind creating a wave on water (yes, air can indeed be construed as a fluid in science). It seems that the effect can go full circle (pun intended) and create what essentially looks like a corkscrew.

Pretty cool, huh? I have only seen this the once and I can only find a few images on the internet that are similar, so you never know, I may have stumbled on a new cloud type! I will name it “the screw-mulus”. Or I could be over-thinking things….yes, the latter.

Now, moving away from science but to return to it in a little while, some sunset pictures I took just because and in the order of this post heading towards the end of the day in subject matter. Not that many sunset images at all this year, seems we have way too much low cloud now, so there will be fewer and fewer of these images of feathery loveliness…

This next one is an unusual one as there are quite a few “straight” lines in the cloud. I say straight with a little bit of a nudge as they aren’t ruler straight, but in nature, you very rarely find anything too straight, so when you see it, it’s usually due to interaction with something unexpected…in this instance, I suspect the contrail on the right at a similar angle has something to do with it.

Back to science! Rays. In particular, crepuscular rays. I have posted many images on here of these rays but now I present to you a rarer image of….anti-crepuscular rays. It is pretty much the same thing but you see these opposite the sun, not around it, behind a cloud or such like. The rays are caused by the interaction of the light with an object out of your line of sight due to the curvature of the Earth, so as the sun dipped just below the horizon here, a little cloud got in the way, casting this shadow…

Apologies for the dark image, I had to fiddle the contrast to enhance the rays somewhat. However, talking of dark brings me nicely to my last image for this post, a nightscape. I don’t often do these, as it’s not an area I have a great deal of skill in, but I try. I took this of the refinery and fuel storage areas around Pembroke (on the left) and Milford Haven (on the right) from Pembroke Dock.

I even managed to catch a little starlight in the image which was not my intention, but it adds a little depth to the inky black bits. I might try this further in the future, but I find them a little boring being so dark and having a not so well suited camera for this kind of stuff. We shall see.

Well, there you have it for another post. Before I go, just a couple of things…I need one more follower to reach 50 so if you have a friend or relative who can stand my infrequent babble, tell them to pop to my site on a PC and click the “Follow Me” link at the bottom right. Thanks!

Also, I have changed a few bits on the site such as the background banner and post text. Hard to read, too small, too large? Constructive criticism is very much welcomed!

Cheers in advance and see you soon.
