If I were to stare at this with my eyes for too long I am sure my eyes would never recover.

With 700 Lumens of light coming from a single LED and even being behind a diffusing lens, all the eyes would see is blinding white. That's where the camera can see something we cant; the detail.

In the very centre you can see the square shape of the square LED die and in each successive hexagonal element it is progressively displaced off center. By shifting the colour balance and saturating the differences you can really see how the diffusing lens not only 'diffuses' the light but also creates a rainbow of colours as the light refracts through the the individual elements.

Well after its long stint and now almost a landmark on the western Adelaide plains the Cavalia big top is being topped!

The the company with its performers, the horse and its entourage are all gone, the internals have been cleared away and the gutted big top now stands like an empty shell.

So long Cavalier, you were a great landmark for a little while but soon you will gone elsewhere.

In 1848 a two-masted 225 ton wooden brig named 'The Tigress' set out from Scotland with a load of general cargo bound for Port Adelaide, South Australia. After such a long and difficult journey she made it to within 50 nautical miles of Port Adelaide before gale force winds swept her onto reef south of Port Noarlunga. In the subsequent efforts to get to the shore two souls were lost, the captain Alexander Guthrie and a passenger Francis Frew.

In 1970 the Scuba Divers Club of South Australia moved the anchor from the original Tigress wreck site and placed it here at along the reef at Port Noarlunga.

Most divers who dive the inside reef at Port Noarlunga are unaware of the history here and simply use this as the half way marker for their dive.

My thanks to local maritime historians Steve Reynolds and Christopher Deane and their web articles for the back story.

The outer reef at Port Noarlunga is not dived very often as most divers prefer the protection inside the reef.

Make the effort to climb up and over and large schools of playful big silver drummer Kyphosus sydneyanus will zoom in to investigate. Here the drummer like to play and feed in the impact zone and feed on bits of algae debris in the turbid white water. At low tide when the ocean does not break over the reef they just seem to want to play games with each other as they wait for the rising tide or swell.

All the travel advertisements seem to espouse the beauty of white sandy beaches, the finer the sand and the whiter the better!

I love beaches of shingle. They seem ancient and speak of harsh conditions where fine sand would have or has been completely swept away.

The best part of all is not having to clean the sand out from everything when you leave!

Passing by the 'Cavalia' big top almost every day has given me the chance to see so many different moods of this curious structure.

This view is just a little different with a wide open lens and intentionally out of focus.

If you are a local and spend most of your time around the Adelaide metropolitan beaches then you could be excused for thinking we are looking south.

Many Adelaide visitors make this mistake and then wonder why they can't enjoy the sunset here. This view is looking west and now that we are heading into summer the sun will still descend behind the headland.

I don't usually make the effort to explore the coastline around Rapid Bay, at least not above the the waterline. I plan to do it more often.

For some reason while standing here I could not get that childhood nursery rhyme out of my head.

"Baa baa black sheep have you any wool? ...". Except these sheep only had black heads.

We have some of the most colourful and interesting sea stars here in our Southern waters but I have to admit that I often overlook them as I search for the more 'exotic' creatures such as nudibranchs, cephalopods or dragons.

Sea stars are everywhere and not just many of the same type but a wide variety of species as well. Even sea stars of the same species often look very different from each other as any biscuit star will beautifully demonstrate.

While diving near the 'T' at Rapid Bay Jetty I came across this Red Sea Star, Pentagonaster dubeni, which was as visually conspicuous as an orange safely flare as it sat perched atop some bottom structure.

Perhaps I will pay a little more attention to the sea stars in the future and give the 'exotics' a break for a while!.

Anyone who has dived Rapid Bay Jetty over the last 6 weeks would know how bad the visibility has been.

There have been days there when you could not see more than 50cm through the milky brine which always seems to follow a period of northerly fetch. I have heard many different opinions on why the visibility here is so changeable. Some people suggest that it has been 'bad' since the new jetty was built a few years ago due to disturbance of the sea bed however I can remember these 'milky' days from when I first started diving and the original jetty was still intact and in use.

My thoughts are that the 'milk' is cause by colloidal gypsum, a legacy of years of gypsum loading here and the the long term exposure of the area to gypsum dust both directly and through run-off.
I am sure the sea bed surrounding the area is loaded with this super fine gymsum. A prolonged northerly fetch creates a ground surge which lifts the dust back into the water making it milky blue.

The visibility here is very good at the moment at around 10-15m. It's an odd kind of visibility with the the milkiness still there but at least now you can enjoy the old wives swimming among the pylons.

I came across this pair of cuttlefish hovering over the broken bottom under Rapid Bay Jetty.

At first I thought they might be juvenile giant cuttlefish (Sepia apama) but as I watched I started to wonder if they were already full grown.

After some research and further deliberations I've decided the only thing I can be sure of is that they are very cute regardless.

Anyone who has seen the movie 'Life of Pi' will be familiar with the gorgeous golden tones the producer has rendered into some of the cinematic sequences.

It reminded me of how the 'golden hour' has become almost sacred to me in terms of filling the world with the most gorgeous light imaginable.

Here is my local Henley Beach in all of its golden glory!

The sunset photographers were out in force tonight down here at Henley Beach.

What started out as a promising spectacular sunset with the sun periodically bursting forth from rents in the cloudy western sky soon proved to be a little less than hoped for. There was just too much cloud and the sun disappeared for the evening well before sunset.

While packing up for the evening I met another local Adelaide landscape photographer David Fielding and we spent the next half an hour on the cold and windy foreshore discussing landscapes, lightroom and luminosity! (As you do!). If we had been a little smarter the cafe just back from the beach would have been a better option.

The cold eventually took its toll and I grabbed this last image before heading back home.

I have now seen three difference species of ray down at a Rapid Bay over the last few days.

This guy is a masked stingaree (Trygonoptera personata) and although common to South Australian coastal waters was not actually recognised as a unique species until relatively recently, in fact, about the same time I learned to scuba dive.

When I had seen these on previous dives I had mistaken them for juveniles but this little guy is probably a fully grown individual and was happy to just lay there and watch as we watched back.

Over the last month I have been following the progress of a brooding Tasseled Anglerfish (Rhycherus filamentosus) with a clutch of eggs.

I have been quite wrong about hatching timing with my first prediction being the last week of October. Finally the little guys are hatching and on this dive I save and watch for nearly an hour as some of the little anglerfish worked their way out of the casing. This is where it gets interesting.

During the early stages it looked like the clutch was attached to the back wall of some structure and the parent lay against the eggs to guard them. On this dive I watch the parent collected the the large mass into a single large clump and vigorously shake them sending little anglerfish who had hatched but were stuck in the egg-mass to be thrown clear.

In this image you can count at least two babies already clear and the one in the centre just emerging from its shell.

Our local Southern Calamari, Sepioteuthis australis, are amazing creatures able to change their body colour at will to match the surrounds.

During a moonless night however their chromatophores attempt to match the darkness and saturate with all kinds of intense colours. The moment you hit them with a a flash of white light they they show colours you would never have imagined. Just beautiful!

Despite the darkness this guy is keeping an eye out as we are diving in a popular squidding location off Rapid Bay Jetty. I'm sure he's safe from the chef's pan, at least for now!

Inside this 'Disneyland like' structure is Cavalia, I am told one of the greatest horse shows ever!

Also inside the tent is the rest of my beautiful family reveling in the experience. So why are they on the inside and me on the outside? Now I am asking myself that very same question after being told I would have loved it.

Oh well I got a good photo of tent at least.

Today I did the rounds again checking up on my expecting anglerfish and leafy sea dragon and keeping up with the general comings and goings under Rapid Bay Jetty.

While I was down there a school of Six-spined Leatherjacket (Meuschenia freycineti) decided to make me their leader and follow me around. Where I turned around to take a photograph the question on their lips was obvious.

A few days ago there were four baby Tasseled Anglerfish (Rhycherus filamentosus) in this location.

When I came back and saw only one my first thought was that something had taken (eaten) them. Now that I have the image on the screen it is clear that they have 'hatched' and left of the own accord.

I am driving through Myponga every other day now and passing through so much gorgeous scenery.

Most of the time my camera is still entombed in its underwater housing but this time I did my best to dry off the housing and retrieve it on route.

There are so many wonderful views of the Myponga Reservoir and I will start to explore them but for starters I've just pulled over on the side of the road just out of Myponga and captured the view from there.

Something scary for Halloween!

Unlike a bulldozer the nudibranch (sea slug) Ceratosoma brevicaudatum eats its way through its path rather than pushes it.

This little guy would have to be one of the most common nudibranchs seen be divers along our southern coastline. A regular on both Edithburgh and Rapid Bay jetties, Ceratosoma brevicaudatum is both large at 5-10cm in length and colourful making it easily spotted by divers not skilled in finding its smaller cousins.

This nudibranch at Rapid Bay Jetty today looks to be feeding on a pink/purple sponge making a striking contrast with it own colours!

Out the front is a for sale sign. The fences are torn down in places. Dirt and rubble have been piled high where a driveway once had been.

Standing inside the remains of this farm building and watching the sunset had me wondering just how long ago the sun had set on this forgotten place.

Over the last few weeks I have been following the progress of a brooding Tasseled Anglerfish (Rhycherus filamentosus) with a clutch of eggs.

The father is still in his place guarding the clutch and in the last couple of days has started fanning the eggs with his tail. Here four little eggs have become detached from the mass and fallen to the bottom but still very close and probably safe where they are.

On inspection of other eggs I see very small yolks still visible but as they are almost gone hatching should be in a day or two.

Sometimes you do not even need a tripod and simply resting the camera on the ground will suffice.

Having a camera at ground level does however have its risks. I had to pluck the camera to safety a moment after I captured this image as that wave washed over the foreground pebbles. Better they get salted than my camera.

Yet again another image of Rapid Bay but one from a vantage I have never tried before.

It's easy to imagine that above those stilts of legs there is some alien spacecraft just touched down in a primal sea.

Any moment now an under-hull hatch will open and other-worldly visitors will descend to explore their new discovery.

Thanks Jennifer for your imagination. Up until then it was just a jetty!

There is definitely a dark side creeping in to my work.

There was an awesome sunset tonight. A wonderful mix of sun and cloud and sun and cloud as the sun sank through shutters of dark and gold. When the sun was well gone the clouds lit up with oranges and reds. The the last burning
embers int the sky contrasting the greens and purples in the sand and in the sea.

Tonight we got at least fifty shades of awesome.

Candid photography is both more interesting and easier from unusual places.

Here looking down I saw this man framed within a gridded network of tiles. My perspective made the grid the defining subject. The man, well an interesting foreground subject.

Today was one of the windier ones with powerful northerlies ahead of a westerly front.

Late today I thought I'd try some long exposure shots of windy Henley Beach. The strategy was simple.

1. Guess the aiming of the camera and all the required camera settings with the lens cap on.
2. Quickly remove the lens cap and capture a single long exposure.
3. Face the camera away from the wind and clean the salt spray off the lens.
4. Repeat.

With the driving wind and long time exposure it was almost impossible to keep the camera still on its tripod. Of all I think this one came out the best.

I was recently reading an article on photographing clouds as backdrops for compositing. I do not do composites from different times and places so I only half paid it any attention.

For me if I am going to photograph clouds it is because I see something extraordinary. Fortunately, and with the recent weather we have been having, this happens regularly.
