All the Colours of the Sea

This last Saturday was a banner day for photography. My new Canon G11, which you are undoubtedly getting tired of hearing about, was perking along nicely, grabbing shots with much increased dynamic and no noise whatsoever at ISO 80. The ten megapixels that it offers are more than sufficient for the magazine-size shots that I need to do my work. Don’t sniff at ten megapixels. If another camera offers more, but the resulting image is poorer in quality, what good do those extra megapixels do?

Yesterday’s post contained images from this Saturday’s dive also, as will tomorrow’s and the day after. In total, out of about one-hundred exposures, I got thirty-six which I deemed good quality. I’ve never had a two dive day that was more productive. Part of the reason for that was that my old buddy, Richard Jones, was “spotting” for me. He has amazing eyes and can find the smallest critters. Sometimes these are the most interesting. Tomorrow I’ll feature some nudibranchs which Richard found. Your mind will be blown.

But, that’s for tomorrow. Today, we’re doing colours. The dive at Planet Rock  was dark. There was a layer of muddy fresh water from the Gol Gol River  floating over the surface down nearly to the top of the sea mount at about 15 metres. I had to take many shots with flash. Though it is my preference to forgo flash when possible, sometimes it is unavoidable – there’s simply not enough light. In the first two shots, the effects of the flash are not noticeable. It simply acted as a fill light. In the others, the effect is dramatic, though the colours are, to me, artificially bright. They are, however, very pretty.

Green has been my favourite colour since I don’t know when. When I was a small child, it was red. I don’t know when I changed to green. I don’t even know if guys are supposed to have a favourite colour. I don’t talk about it much over the pool table with my mates, though I’m always soothed and mellowed by the green playing field. Maybe that’s why I’m such a lousy shot. Anyway, have a look at this lovely green Coral (Acropora tenuis):Click it to magnify and see the lovely details of the polyps waving in the current. Each little ledge on each tower is an individual animal. It is truly a thing of beauty.

Here’s another Acropora  species with a dramatically different colour:I’m always faintly startled when I run across one of these outlandishly purple corals. They seem somehow out of place. I wonder if a nearby toy store exploded and scattered misshapen shards of bright plastic on the sea bottom.

This shows why we have a pretentious name for the Magnificent Anemone (Heteractis magnifica).  You can see a scattering of  Pink Anemonefish (Amphiprion akallopisos)  chilling out and having a few beers:What a lovely playground they have.  There are few sights in the sea which are as calming and wondrous as this symphony of colour displaying a commensal relationship between vastly different organisms. Neither can flourish without the other.

Starfish fans will enjoy this lazy looking Linckia laevigata.This is the same species which often appears as a bright blue variation.

This Coral (Lobophyllia hemprichii)  contains the brightest red pigment of any creature that I have seen in the sea:This is a very young colony. They tend to become less colourful as they grow. Young ones, such as this, can often be seen as tiny crimson torches thirty metres away on a day with good visibility.

I’m a great fan of Feather Stars. This is a particularly nice image of some species of Lamprometra.  They are difficult for me to tell apart. I’ve been watching old episodes of Fawlty Towers  during the fifteen minutes that I can stop working each day. I can’t get out of my mind what Manuel (he’s from Barcelona, you see) says when he misunderstands a command from Basil Fawlty: “Eet ees deefeecult.”You can clearly see the “feet” of the feather star in this shot. If you gently tickle a foot with your fingertip, the creature will wildly thrash its arms around, waving madly. It’s a most comical sight. I’m going to have to shoot a video clip of it some day.

Here is a close up shot of another individual of a Lamprometra  species Feather Star:I didn’t think that the shot would turn out to be much. Now I’m simply blown away by it. Beware. If you stare at it long enough you may feel yourself getting slightly high, that is if you recognise “high”. Click on it to make it bigger and have a look. It’s mesmerising. This is a living thing. How can that be?

I don’t recommend it as a desktop background.

First Drenching of the Canon G11

I won’t waste your precious time today with a lot of blabber. My own semi-precious “time for myself” is withering as my workload increases while my pay simultaneously shrinks. However, I did have a bit of fun today. I did my first dive with my new Canon G11 in its cozy factory housing.I still have a lot to learn about squeezing this new lemon, but first results have me feeling dreamy and wishing I had time for a mid-week dive.

The current at Magic Passage was raging and I had two divers with me with whom I had no experience, so I didn’t get much chance to shoot. I did get enough frames to tell me that I like what I’m seeing from the G11.

Here is a pretty ordinary shot of a Silver Sweetlips subadult (Diagramma pictum).  You’ve seen these many times here before, and much better images. However, this was a snap shot which I did not even expect to save. With a few minutes work, the G11 image came out acceptable:Here is a mob of what I think are Lunartail Snappers (Lutjanus lunulatus)  finning vigorously against the current. Again, as a snap shot, I’m very happy. The G11 seems to save more images from doom because of its increased dynamic range (the range of colours and shades that it can record accurately under varying conditions) and its lower noise level:Again, I didn’t expect for this image to be usable.

Here’s a sweet shot of a Circular Spadefish  or Batfish (Platax orbicularis)  that really illustrates how the two extra stops of dynamic range allow me to save a nearly impossible image:Where I would have had muddy dark areas and blown out highlights (such as the top of the frame), now I have decent detail in the very dark areas and smooth gradations with colour detail left in the very bright areas – just what I was hoping for.

I never pass up a chance to photograph the ridiculous Blue Starfish (Linckia laevigata): When God was a little kid, he left some of his toys scattered around the planet. This is one of them.

Here is a close up shot of this very special toy:The detail is amazing. I’ve lost no ability to capture fine details by dropping from 15 to 10 megapixels. I think a lot of the extra megapixels were wasted because they were too small to gather enough light to put together a decent image. The pixel race is over.

Here is a reader favourite and mine also, the lowly Hermit Crab (Dardanus sp.):This little fellow will soon be receiving a notice from the Neighborhood Association for painting his house such an outrageous colour.

Back tomorrow with more wholesome G11 goodness.

Starfish Day for Julie

Julie, a Facebook Friend, tells me that she really digs starfish. Because I can use all the friends I can get and Julie never scolds me for attempting a humorous comment on her status changes, I think that her polite hint deserves an appropriate response.

Since I do, despite my geeky aura, appreciate the sentimentality evoked by images of starfish, I’ll set the stage with this mushy shot:

I can hear the murmurings of “Awwwwww . . .” from here. I have no idea who the people were. They simply happened to be standing on the rock while I composed the image. It was a very lucky break.

The truth is, I nearly overstayed my prime time. During an attempt to catch the sailboat out on Astrolabe Bay,  I was nearly inundated by a wave crashing on the rocks:Now that I’ve set the mood in my inimical way, we shall proceed to tickle Julie’s fancy with some yummy starfish.

You know, I’ve seen  this shape before.  There is a logo somewhere, on a product or representing some organization, that is a cartoonish figure of a starfish (two eyes, a mouth, etc.) with the top of the star a little crooked, as if it were wearing a hat which is a bit askew. This Fromia milleporella  reminds me of that:Please keep in mind that this is Annual General Meeting week and I’m sitting here trying to stay interested and not fall asleep. My mind wanders in particularly unusual ways. I keep feeling fluid draining from my sinus cavities. It’s seawater. My wife, Eunie, tells me when to raise my hand to vote on a motion. As you can imagine. I’m a little more distracted than usual.

But wait! Let’s get back to Julie’s starfish. This is one that you’ve seen here many times, the lovely Choriaster granulatus:You may be tiring of seeing this critter, but I’m nowhere near finished taking pictures of it.

Here’s is another which you have seen here many times:I’m sure that everyone out there has seen images of the Mimic Octopus which is able to contort and recolour its body in marvelous ways to appear to be any of several non-octopus critters. However, have you ever seen a Linckia laevigata  mimic a snake? As of now, you have.

It may surprise some that this lump is a starfish:Called a New Guinea Cushion Star (Culcita novaeguineae),  it appears more like a bumpy, spiky football. In fact, it is supremely tempting to pick it up and attempt to kick it back and forth between divers using the floppy fins.

Of course, we never actually do  that.

Bon appétit,  Juli.

The Big Blue Finger

Posted in Under the Sea on December 2nd, 2009 by MadDog

I’m sitting here wondering what to say while I listen to some very cool East London Jazz from Seal, which dates my taste in music somewhere in the Early Bronze Age. Later I’m going to do some Steely Dan, maybe Babylon Sisters.  So, I’m all moody and overworked and and I had a bad night walking around in the dark at a friend’s house with a big rock in each hand while attending to an armed robbery. More about that later. So, right now I’m in the frame of mind to give the world The Big Blue Finger!

And (brace yourself)  here it is:

Blue Starfish - Linckia laevigata

Regular readers will recognise one of God’s funnier jokes:  the wonderfully whimsical Blue Starfish (Linckia laevigata).  Actually not all of them are blue. Most are a sort of dull green or yellowish brown colour. I can never help laughing when I see one. I think to myself, “Yeah, I can dig it.”

Since my mood is wandering, let’s look ahead to our next Pagan-Turned-Christian holiday by absorbing the lemony wonderfulness of these Christmas Tree Worms (Spirobranchus giganteus):Christmas Tree Worms - Spirobranchus giganteusThese are among the amazing tiny creatures that I never tire of seeing. It’s fun to see how close you can get to them before pop back into their holes and disappear.

Since I have a few live coral keepers out there who watch this space for mouth-watering samples of what they could be playing with, if they only had a big enough tank, here’s a nice little coral community:Coral CommunityI’m no expert, for pity’s sake, but I think that I can see seven different species of coral in this area which would measure about one square metre.

Here’s one of the better shots that I have managed of Clark’s Anemonefish (Amphiprion clarkii):Clark's Anemonefish - Amphiprion clarkiiIt’s not much good as a specimen shot, because you can hardly see the second white bar which is an identifying feature of this fish, as is the white bar in front of the yellow caudal fin. What you can  see, however are its tiny, razor sharp teeth (and they do  bite!), the clear cornea of his right eye, and a lot of detail in the front white band, which is very difficult to capture, because of the huge difference in brightness between the black and the white. Click to get a larger image.

Now, since I”m not feeling quite so grumpy as before, I shall show you a grumpy fish:Coral Grouper - Cephalopholis miniataThis Coral Grouper (Cephalopholis miniatafdsa)  clearly did not care to be bothered.

That’s pretty much the way I feel today. Eunie has gone to Port Moresby to do battle with the Department of Immigration and Naturalisation concerning her Permanent Residency. I can hardly think about anything else. I told her to not return to Madang until she had it in hand (as if I could order her around . . . makes me giggle just to think of it). I told her very sternly.

She gave me that smile. You know, the one that Mona Lisa did so well.

A Mixed Bag of Nature

Posted in Mixed Nuts, Under the Sea on October 11th, 2009 by MadDog

Best plans aside, I find myself here at the office on Sunday morning. I ran out of time yesterday, so I managed to get only one post finished. Nevertheless, it was good luck, since I got some very nice sunrise shots this morning on the drive to the office. You’ll have to wait until tomorrow to see them, however. I’m still catching up with images.

Coming back from our dive a week ago on Saturday, I had to stop Faded Glory  in her track to get this image of the sun low in the sky over the airport. Dad told me, as he was teaching me photography, over and over, “Composition is King.” Pretty colours are nice. Sometimes we simply want snapshots to capture memories. However, when you’re shooting for something to hang over the mantle, you have to pick your moments and compose the shot with care. I like to think of myself as a painter. I ask myself where I would put my easel, what palette of colours would I use, how do I want to portray the subject, where do I want the viewer to focus?

Two Coconut SunsetThe two coconut trees in the image make a perfect focal point. Researchers have done some very interesting work using gadgets that can record where a subject’s eyes are looking at any instant as they view images. What they have found is that the eyes search out a particular point and keep coming back to it. As the viewer takes in the image and processes it, the eyes dart around the image, stopping at places of interest. Very often, however, the eyes return to a single point of interest. Click on the image above to enlarge it and study it a minute. I bet that your eyes keep returning to the two coconut trees. For an image of a person, the point of interest is almost always the eyes.

Now, let’s take a little trip to somewhere else. I don’t know where it is, but wherever we are the moon comes up in a most startling fashion. Okay, okay, it’s our front yard. A few evenings ago a friend called me saying that I had to run outside with my camera to catch the moon rising. (My friends know me.) I was a little tardy getting out with my tripod and camera, as I first had to dress appropriately. I was too late to catch the huge orange blob just above the horizon, but I’m quite happy with this image:

Psychedelic Moonrise

It can hardly be called a photograph now, since it has suffered merciless manhandling by Photoshop. Nevertheless, it is an interesting image. That’s all that I wanted.

And now, for something completely different.

I can’t pass up certain images that catch my eye underwater. Sea Squirts are among my favourites. They seem improbable to me. They clump together in a manner that makes me think of little hamlets where the faeries live:

Sea Squirts - Atriolum robustum

It seems that I’m waxing a tad too poetic this morning. Still, as faerie houses go, these are credible. The little houses above are Atriolum robustum.

There is a nice big fish called the Midnight Snapper (Macolor macularis).  As with many fish, the juvenile looks nothing like the adult. This is the juvenile Midnight Snapper:

Juvenile Midnight Snapper - Macolor macularis

It’s a terrible shot, but I excuse myself because this fish is fiendishly clever at avoiding the camera. They move constantly out of range (this is a telephoto shot) and always try to hide behind something.

I’ll wrap it up today with yet another image of this improbable Blue Starfish (Linckia laevigata):

Blue Starfish - Linckia laevigata

Not aiming to sound irreverent, I beg forgiveness for imagining God as a kid, scattering around the universe all of the most treasured toys. Surely, this must be one of them.

Ah, Sweet Saturday

The weather the last few weeks has been miserable, at least by Madang Standards. I don’t think that there has been a single day without rain. It has also been very cold. You have to remember, of course, that is tropical cold, not regular cold. When the mercury drops below 24°C (75°F), we call it cold.

However, this Saturday was sunny as reasonably warm. We went to Magic Passage. The surface conditions looked good – little current and clear water. Down at the bottom at about 3o metres, though, it was milky. The current was running sluggishly outward, carrying the foggy-looking water from the anchorage out to sea.

I did manage some interesting shots which I’ll give to you in a gallery without a lot of comment for a change:


The Bigeye Trevally shot is interesting. It was so murky at the bottom that there was virtually no colour. I decided to take advantage of this instead of moaning about it. So, I made the shot monochrome.

Muddy Bottom

Yesterday, I had a boatload of fun seekers, but no divers except me. So I took them to my favourite spot at Pig Island.

In case you’re wondering, here is how it looks from where we were anchored on a sandy bottom:

Pig Island on a Saturday - Perfect Sky - Perfect Day

Since I was the only one diving, I decided to head out into the middle of the small bay where I know that the bottom is muddy. We seldom go down there because most people want to see a lot of colourful fish – not a bunch of muck. If fact, that’s what we call it: muck diving.

I don’t mind it when I have my camera with me, because there are a few critters down there that you seldom see anywhere else. You just have to cover more area to find them.

For example: here is a Beaded Anemone (Heteractis aurora):Beaded Anemone (Heteractis aurora) and Periclimenes shrimp

I like the lovely pale colours. This is one of the anemones that you definitely do not want to touch. It stings. If you click to enlarge, you will see a tiny Periclimenes shrimp. I’m guessing at the genus, because I can’t find this shrimp in any of my references. My books are not all that great, though. Here is an enlargement of the shrimp:

Periclimenes shrimpIf you can see only some dark and white dots with a white bar at the end, then you are looking at the shrimp. The rest of its body is entirely transparent. All that you can see are the pigmented areas. The dark splotch at the left is the tail. The long white bar at the right is the head. You can barely make out the legs.

While still on the muddy bottom, I stumbled across this Beaded Starfish (Echinaster callosus):

Beaded Starfish (Echinaster callosus)

It is certainly an odd looking starfish. I don’t know why it was twisted around so. All around, you can see tracks of burrowing snails.

As I ascended away from the mud into the sandy area there were plenty of Gobies sitting on their verandas. Here is an Eyebrow Shrimpgoby of the genus Amblyeleotris:

Eyebrow Shrimpgoby (Amblyeleotris sp.)Many Gobies have a commensal shrimp that lives in the same hole. I could tell that there was one living with this Goby because of the long ditch leading from the hidey-hole. The shrimp bulldozes the sand from the hole to keep it open, leaving a long ditch-like furrow in the sand. There will normally be a little roof of rocks on the opposite side to act as a roof to keep sand from falling in. Here you can see the ditch leading off to the left and the little roof of stones to the right of the Goby. The shrimp was hiding from me.

Back up on top of the reef, next to the trees that you see in the first image, I found this six legged Blue Starfish (Linckia laevigata):

Blue Starfish (Linckia laevigata)I case you are wondering if I fiddled with the colour, the answer is no. They really are that blue. There is also a greenish variation of this species, but the colour is not nearly so bright. They make me think of those strange, brightly coloured plastic toys that Japanese tourists always seem to enjoy. These normally have five legs.

Diving in mud can be fun.
