The Vain Varicosa

Dont’ try to figure out the title of the post yet. It’s so stupid that you will simply waste your time. I’ll get to it.

Busy, busy, busy. When I went out this morning I was wondering how I was going to cram in all the things that I “had to do” before clocking out. One of them was to take this picture of a sunrise, a very peculiar one:

Frustrated with the violet hue (which, by the way, I saw with my own eyes, but can’t explain), I spent far too much time trying to get rid of it and then decided to leave it, because that’s the way it was. It is not a very good idea to fool with Mother Nature, even when she seems to be fooling with you.

But, getting back to “things I have to get done today”, I really need an attitude adjustment. There are categories:

  • That which must be done to maintain life (eat, get a little exercise, don’t offend any mobsters, etc.)
  • That which one must do to keep one’s job or jobs (should be obvious to you unless you are about to be sacked)
  • That which you would like to do just to show that you’re pulling your load (help with the housework, wash the car, mow the lawn, etc.)
  • That which you need to do in order to maintain some level of personal satisfaction (this too, you probably already have figured out)

The problem is putting them all into some kind of balance. I still haven’t gotten a handle on that. I probably never will.

So, since this is something which I do to maintain some level of personal satisfaction, I’m going to blow off some of the more essential tasks and show you the source of the ridiculous title of this post. It is a nudibranch, specifically a Phyllidia varicosa,  of which you have seen many specimens before:

The title is a stupid pun combining the species name, varicosa,  and vain, which we all understand (“You’re so vain – da da da da da da da.”) with varicose veins and don’t ask me why that popped into my mind. So having established what kind of a day it’s going to be, let’s get on with the rest of it.

By the way, I am calling that P. varicosa  image a perfect specimen shot. If anybody wants to argue that, then put up your dukes and show that you did better. I’m laying the matter to rest until I get (or I am challenged with) a better one. That’s another brag down for the day. How many do I have left? I’ve lost count already.

Here’s a nice, symmetrical shot of  a Fan Coral and a Feather star:

No, I’m not going to say a lot about it. It’ speaks for itself. Let it talk for a few seconds. Pop it up and have a look. Hear anything?

Me neither.

A little gaggle of Shadowfin Soldierfish (Myripristis adusta)  were swimming through the notch leading to the catamaran. Having plenty of air and not much else to do, I took a picture of them:

Think of that shot as part of my continuing efforts to demonstrate that not everything under the sea is as exciting and beautiful as you see it on TV.

This is a bit better. These little devils are usually almost impossible to shoot well. The Blackspotted Puffer (Arothron nigropunctatus)  is a shy, shy fish:

This is probably the best shot which I have ever gotten of the fat little puppy-like swimmers.

Then, a few metres away, I found another one ducking in and out of a hole:

Another good puffer shot. When you’re hot, you’re hot!

Looking back up at that list, I think that I have to get to work now.

A SCUBA Diving Bee?

This morning I was out stumbling around in my garden looking for something to shoot. I was nearly ready to give up, not having found anything that I haven’t already snapped a hundred times, when I came across this small bee wearing a SCUBA diver’s mask:

It’s only Tuesday and I’m already running out of material. When I start pulling your chain about diving bees, you can tell that I am desperate. Yeah, I know that it’s silly, but look at its eyes. I have never seen a bee, or any other insect, with eyes such as this. They are huge. They also have an unusual shape, which I suspect give it an enormous field of vision. This makes me think that it is possibly an insectivorous bee. A bee which hunts on the wing would need exceptional vision. It also does not resemble the standard, flower-visiting bee. I watched it for some time. It was showing no interest in all of the flowers around it. In fact, it gave the distinct impression of a hunter lying in ambush.

UPDATE: Faithful reader and friend Alison Raynor has already nailed down the identification of this bee. It seems that I coulnd’t have been more wrong. Oh, wel. It’s not the first time:

HI JAN,
COULD THIS BE YOUR CRITTER?
Blue-banded bees (Amegilla cingulata) are native to Australia, but also occur naturally in Papua New Guinea, East Timor, Indonesia and Malaysia. Unlike other bee species, blue-banded bees are solitary insects. They typically build nests in sandstone, mud or the mortar-gaps in the brickwork of houses.

Blue-banded bees specialise in an unusual sort of flower pollination called ‘buzz pollination’. Normally flowers release pollen passively, but some species are specially designed to be pollinated by ‘buzz pollinators’ that grab onto the flowers and vibrate them quickly to release the pollen.

Okay, the bee doesn’t dive, but I do. I ran through some more frames from our dive at The Eel Garden last Saturday and found a few which may amuse, if not amaze you.

Though this will probably mean little to you, I can testify that this is an unusual image. This Sea Cucumber (Thelenota anax)  does not belong on this bumpy coral. It is a creature which gobbles up sand by the bucket, runs it through its innards, sifting out the digestible bits, and then excretes the sand out of its other end:

Why it is wandering around up here on this coral shelf, metres away from its feeding ground, I have no idea.

The lower fish, whiskering around in the sand, is a Goatfish, specifically a Parupeneus forsskali:

They feed by bulldozing around in the sand, throwing up big clouds of “dust” and using their whiskers to find food. The other fish is a Redbreasted Wrasse (Cheilinus fasciatus),  a fish which usually stays far enough away to be difficult to shoot. It is not unusual to find other fish hanging around where a goatfish is feeding. They often stir up items which do not interest them, but other fish find tasty.

This is a Longnose Butterflyfish (Forcipiger flavissimus):

It’s not a particularly good shot, but my excuse is, as usual, they try to stay at a distance. How they calculate the distance at which it becomes nearly impossible to shoot them, I don’t know. They must know more about cameras than I do.

This is a reather handsome Soldierfish named Myripistis amaena.  His friends call him Misty. He has a gender identity problem. That’s why he wears the butch outfit:

Chain mail is very “in” at the bars where he hangs.

You are undoubtedly tired of the Phyllidia varicosa  nudibranch. Well, you may as well get used to it, because it is one of our more common varieties and I haven’t got the absolutely perfect image on one yet:

I’ll let you know when I do.

Sharp and Smooth

Weekdays come and go. My last work week consisted of exactly one day – Friday. Wouldn’t it be nice if Friday was the only work day? You could go to work in the morning knowing that when you clock in you are beginning your week and when you clock out, it’s the weekend again. Pay might be a problem, however. I’m working on a plan to live without money. If I get it worked out, I’ll let you know.

And following my one-day work week came Glorious Dive Day! I had nobody going out on Faded Glory  this week, so I skipped all of that boat loading and unloading and just went out with Richard Jones on Sanguma.  I have to admit, I really like getting picked up at my front door. It’s quite a treat compared to my usual Saturday routine.

The dive was quite nice. The Eel Garden was putting on a fine show. I got some very nice underwater shots. However, as it sometimes happens, my favourite shot of the day has nothing to do with fish. Ush is one of my favourite photographic subjects, at least when she is not too shy. I kept seeing wonderful reflections in her cheeky red sunglasses. A little coaxing got her into the mood to pose for me:

When I first saw the result on my computer screen I was not overjoyed. Though Ush gave me just what I wanted, my exposure skills were not up to snuff. It took me the better part of an hour to massage the image into what my original vision demanded. I wanted the sharpness of the sunglasses and the reflections, but I needed Ush’s skin to be as soft and smooth as a baby’s bottom. Well, it pretty much is in reality, but cameras are harsh to skin, as we all know. I’m happy with the finished product. It’s the most fun I’ve gotten from a single image for quite a while.

Now this one . . . this one is a mistake. It was so bad that I nearly deleted it. However, I sometimes like to play the photographic savior and redeem otherwise worthless frames:

The Soldierfish was swimming away, it was too distant, and the light was all wrong. On top of that, I had my flash turned on, which threw off the colour balance. I know! I’ll call it “Art’.

Richard Jones came over to me with a rock and seemed quite excited about it. It took me a moment to realise that on that rock was a nudibranch which I had never seen before. Of course, I took its picture. It’s a Phyllidia ocellata:

I have to say that it is probably the most humorously patterned nudibranch which I have seen. Some nudis are ethereal in their beauty. This one is wearing a clown suit.

I should know the name of this Planaria, more commonly called a flatworm. I got this shot standing on my head, because it was under a ledge. I’ve turned it right-side-up for you:

It’s Sunday afternoon, and I’m not going to look it up. Somebody out there help me. It’s very common here.

I’ll finish up with a couple of “Deep Focus” reef scenes. As several readers have pointed out, there is nothing special about these high depth of field shots. It’s just a matter of setting your camera right and having favourable shooting conditions:

However, I have noted that few underwater photographers actually do it. It seems as if nearly everybody either shoots macro shots of little things or big, gaudy scenes shot with super-wide angle lenses and multiple flashes.

I don’t see many shots such as these which use a cheap camera and a normal lens stopped down to achieve maximum depth of field:

I find them pleasing, because when I seen them I can honestly say, “That’s just the way it looked to me.”

Someday, that is going to come in very handy for me.

Parrotfish and Deep Focus

Posted in Under the Sea on May 30th, 2010 by MadDog

Saturday dawned brilliant and promising. I was looking forward to going back to The Eel Garden near Pig Island  to find the Leafy Sea Dragon which has been reported to be on the old catamaran. I looked in vain for it last week, but a fellow diver, Hendirck, told me that he had found something promising. In return for the information, I dragged out my old Canon G10 and its underwater housing for him to try out.

Unfortunately, with all of the juggling around of cameras, housings and memory cards, I managed to show up at Magic Passage for our first dive with my G11 showing “NO MEMORY CARD”. Ai ya yai ya yai!  Stupido!  So, I did a very nice dive on which some very interesting critters were spotted, but I had no camera.

Never mind. I pretended to enjoy it, playing Divemaster and pointing out all sorts of fascinating items which I determined to burn into my brain memory cells instead of my usual memory contained in my camera. The camera is much  more reliable.

On the second dive at The Eel Garden, Rich Jones was not diving, so I used his new G11 which was out on its virgin underwater experience.

There were many very colourful parrotfish about. This is simultaneously exciting, euphoric and frustrating. If you are a snorkeller or diver you understand the first two. If you are an underwater photographer you get the latter. Google parrotfish and look at the sad offering of images. It is nearly impossible to get close to them. You must depend on the occasional quick shot when one darts past:

I don’t know the species of the one above. My fish book is at the office and I have photographed so few that I can’t remember most of the names.

This one, I do know, but I would call it a “failed” image:

It is a Hump Head Parrotfish (Bulbometopon muricatum).  They are huge. This one was at least 1.5 metres long. Unfortunately, they are delicious and easy to spear. In some areas of the South Pacific they have disappeared completely. This was a quick snap shot at the end of a long tiring chase during which I managed to corner it long enough for a very poorly framed image. The closer you get to them the bluer they look. I was about two metres away from this one in fairly dirty water.

I’ve been playing around with a photographer’s technique called “deep focus”. It sounds exotic, but it is easy to understand. The smaller the hole you are looking through, the more “depth of field” you will get. In other words, objects from near to far will be in focus if the hole is small enough.

Theoretically, a pinhole will have a focal range from very close to infinity. So, the larger the number of the f-stop you use on your camera (the size of the hole through which the light passes) the smaller the hole will be. I know it sounds backwards, but never mind. Big number – small hole  – more depth of field. That’s the way it goes. If you can get f 16 on your camera, you will get lots of stuff in focus from near to far. At f 2.8 you will get only near or far, but not both.

It works better for non close-up stuff. For instance this shot of the Nudibranch Phyllidia varicosa  doesn’t show much effect:

Sure, most of it is in focus, but there is not much to show the depth of the image. There are no obvious visual clues to indicate depth.

It this shot of coral with an anemone in the background, however, there are many clues to indicate distance:

It requires a lot of light to use the small lens opening, because not much can get through. If you don’t have enough light, you will be forced to use shutter speeds that are too slow to give sharp images. There’s no free lunch. You can have it one way or another, but not both. I manually blurred and darkened the very distant objects at the top to enhance the effect.

In both of these images I failed to note that when I changed the mode of my camera to Aperture Priority (meaning I get to set the aperture and the camera automatically sets the shutter speed) I lost my format setting and it reverted to JPG. I always shoot underwater in the RAW format mode because it allows me much more colour control. Sorry to bore you with these arcane details, but there are a few photographers out there who are constipated enough to care about these things.

Here is a pretty scene, never mind the colours are off, of some coral with Purple Antheas swimming around:

It nicely illustrates the reality which you can get with the deep focus technique.

Okay, that’s it for me. It’s Sunday evening. The sun is below the yardarm. I’m going for a wee dram and lay on the bed to watch some mind-numbing TV for a while. Then maybe I’ll rest my eyes for a bit.

Growing New Legs

Today we went up to Wongat Island to do The Green Dragon B-25 Mitchell bomber and The Henry Leith. The bomber went fine. I got some nice shots which I’ll be showing soon. However, when we went to do The Henry Leith, I brilliantly decided to anchor the boat at the beach so that the ladies could snorkel while Hendrick and I did the wreck. Than meant that I we had to dive off of the beach and I had to remember where the wreck was. I’ve done it many times before, but years ago.

Of course, I couldn’t find it. It’s only twenty metres down, but the water was too dirty so see more than about ten. The bottom where the wreck lies is at twenty metres, so we followed that contour in the area where I thought it was. After fifteen minutes, we gave up and came up to the shallow reef to shoot some pictures. This was my second dive on a big 80 tank. I ended up with 110 minutes. I was using my gills most of the time.

This is a cute little starfish missing only one leg. That’s pretty good by small starfish standards. This one is about five or six centimetres across. I’d say that about half of the starfish that I see are missing at least one leg:I think that it’s a Linckia multifora, but I’m not sure. It doesn’t look quite right.

However, what happens to the leg, if the fish which bit it off doesn’t like the taste? Well, we simply grow a whole new starfish from the leg. Some people call them arms, I call them legs, since we don’t walk on our arms, do we? Here on this severed Linckia multifora leg, you can see four tiny new legs growing out of the severed end:This is a pretty cute trick. Many organisms can do this. Medical researchers are busting their guts trying to find a way to mimic this behaviour in humans. The reason is obvious. Whoever solves the problem first will become the richest person on the planet.

Here is an absolutely lovely young Electric Swallowtail nudibranch (Chelidonura electra): Older specimens develop a lemon yellow edge around the edges.

This particularly nice Divericate Tree Coral (Dendronephthya roxasia) caught my eye:It’t quite lovely and I certainly appreciated the pleasure of seeing it.

However, this is my choice of the day for the shot which pleases me most:The little Glass Shrimp (Periclimenes holthuisi) is about as big as your thumbnail. He has several buddies swimming around him.

They are a nightmare to photograph. They are very small and don’t like the camera up close. They never stop moving, hoping around from place to place and waving their little pincers. Flash photography is useless; you have to use available light. Finally, they are nearly invisible in the first place! You can not see their bodies, only the spots.

It’s like playing “connect the dots”.

A Model Model

I have been feeling very anxious and incompetent for the last month. I was having a difficult time understanding the cause of my feelings. This, of course, simply made matters worse. As I’ve mentioned. I’ve taken on another job aside from my duties in the IT Dungeon. I’m now the editor of two quarterly magazines. It has finally dawned on me what the cause is of my distress. I haven’t had a new job for thirty years. Studies have shown that starting a new job is one of the top stress generators. I had forgotten the feelings of inadequacy, loss of control, uncertainty and raw fear that accompany a new job. I’ve been an author for a long time. However I’ve never been an editor. The job seemed simple when I took it on. It is only now that I’m into it that I realise how little I know about what I’m doing. Wish me well as I struggle to get myself oriented. I’m on a three month probation, so I don’t have much time to prove myself. It’s sink or swim time. Keeping this job and doing well at it so that I have a future in the industry is an essential tactic in our survival strategy as churches will undoubtedly continue to abandon us as we age.

However, today’s sunrise cheered me up:Nice sunrises are getting more and more frequent.

On Saturday we did a dive at The Eel Garden  near Pig Island.  The weather was horrible. We immediately ran into rain and it rained nearly the whole day. Only in the last hour did we get a little sun. Underwater, however, it was beautiful:

A beautiful lady is always a welcome addition to nature’s own. Above is Genevieve and a Magnificent Anemone with Clown Anemonefish or “Nemo” fish.

Here is another one of Genevieve with a Feather Star:

Taking inexperienced divers into my care and teaching them how to enjoy safe diving while learning the mysteries under the ocean is one of the more pleasant parts of my life. Genevieve comes to us with few dives and had not dived for about a year. I expected the jitters and problems on the dive. I was surprised that she was as cool as a cucumber, stayed close to me and interpreted my instructions perfectly. Being an excellent swimmer, she also moves through the water gracefully.

I trapped these Scarlet Soldierfish (Myripistis pralinia)  in a little cave: I had to laugh into my regulator as they darted around crazily as their teeny-weeny brains tried to figure out what to do.

We found the big patch of anemone’s near the island and it was full of  Red and Black Anemonefish (Amphiprion melanopus):I’m sure that this one believed that I couldn’t see him. The will often try to position themselves in the anemone so that only the eye is exposed so that they can keep it on you. I think that they don’t realise the their noses are fully visible.

I’ll finish up with a critter that is probably beginning to bore you.:Yes, it’s the nudibranch, Notodoris minor  again. I’ve found where they are living and I’m to keep on taking pictures of them as long as they are there. It’s a moderately rare species, so I want to “collect” as many as I can. Each image is like a trophy to me.

The Half-Eaten Gumdrop

Once again, I find myself in the middle of the evening trying to catch up with the day. How did I hustle so much and accomplish nothing that I can call progress? It seems to be becoming a way of life. How thought provoking. The harder I work the less I accomplish. I spent half the day putting little tags on wires so that I can tell where they go. I’m drowning in wires! Throw me a life-preserver. No, wait. That’s a mixed metaphor. I’m strangled by wires! Throw me a hatchet.

This Bannerfish exasperated me from the moment I met it. First, I couldn’t get close enough for a shot. I had to chase it, something which I usually avoid, since it usually simply burns up oxygen. Then, when I finally set up a successful ambush, it sped away so fast that all I could manage was a quick panning shot. I’m surprised that it turned out so nice:More consternation arose when I tried to identify it. After a search through my pitiful collection of references I spent a few fruitless minutes with Google Images. No luck. Phooey!

UPDATE: Thanks to my old pal Tris  for jabbing me in the ribs to point out the the fish is not a Bannerfish at all, but a Moorish Idol (Zanclus cornutus).  Thanks for “helping” me, Tris.

The Bigeye Trevally (Carnax sexfasciatus)  at Barracuda Point  on Saturday were splendid. You don’t really have to chase them. You simply swim closer and closer as they whirl around.  This shot was snapped at less than two metres:I soon have to back off to slow my breathing. I let them meander around me for a minute or so and then join the procession again.

The problem with Trevally is that they are so blasted shiny! It’s very difficult, with a small-sensor camera such as my Camon G11, to get enough dynamic range to capture the dark and mid-range tones without blowing out the whites:Still, I’m happy with these shots. Even after chasing them, I still got two dives and over 100 minutes off of an 80 cubic foot tank. My gills are working just fine.

Here is a not too wonderful shot of some Midnight Snappers (Macolor macularis):The interesting bit is that we have adults and a couple of teenagers. The juveniles are black and white with spots and bands. You can still see a trace of the juvenile colouration and pattern on the two teens in the middle.

This is a perfectly normal Pyllidia varicosa  nudibranch:Vaguely amusing, eh? They are easy to photograph, so I tend to show you a lot of them. I wouldn’t be surprised if you’re getting bored.

Okay, how about this one which has had a chunk bitten out by a predator:It’s the Half-Eaten Gumdrop mentioned in the title.

Many nudis remind me of some kind of fancy candy and, strangely enough, take me back to Vienna. The Austrians go for the fancy candy. There are shops which sell nothing else.
