Sulphide Street Railway Museum, Broken Hill

I have always liked railway museums - I guess partly because as a kid, I spent time train spotting in the days just before steam was discontinued and partly because the English are mad keen preservers of industry.
These days I like shooting images of railway equipment using HDR techniques.  HDR or high dynamic range photography involves taking multiple different exposures of the same subject, preferably using a tripod, then using specific software to assemble the bracketed frames into an image that shows a wider range of tones than you would normally get with a single shot.  Typical software used to combine the bracketed shots includes Adobe Photoshop, Photomatix Pro and Nik HDR Efex, to name just a few...
Because of their metallic surfaces, thick layers of grease, rust, and wear and tear (not to mention their history), these ageing mechanical monsters work beautifully in a high dynamic range image.

Another reason to like railway museums is the colours. 
Aside from the fact that the HDR process has exaggerated the hues in this shot of a steam locomotive from the Silverton Transport Company, you just never see that kind of green any more.

HDR is good for holding on to deep shadow detail without losing the valuable highlight tones - which is what you'd lose if this were a single shot.

Amazing to see how much wood was used in the construction of these railway carriages. 
All the electric lamps had glass lampshades.

High Contrast Landscape - High Contrast Black and White

Some time ago I paid $350 or so to have an old Canon EOS400D converted to shoot (only) colour infra-red images.  It's a neat thing to do with a completely superseded (and somewhat worthless) old DSLR camera.
I used to shoot a lot of (real) infra-red film back in the day - so shooting digital black-and-white is a cinch - no tripod, no ultra-slow shutter speeds shooting something you can barely see through the deep red filter used to get the IR effect.  Once converted you just use the camera as you would shooting for colour - only using a special custom White Balance that the [conversion] company sets for you.
You can then use the colour IR RAW files it produces and convert those to black-and-white or shoot black-and-white JPEGs.
Here are some evening shots taken in Broken Hill's signature Living Desert sculpture park nine kms out of town.  It's a very harsh environment so I thought the stark IR effect particularly applicable. For those interested, I sent the camera to LifePixel in the States for the conversion. The company had a special on at the time so it cost a lot less than If I had sent it to Melbourne for the same conversion (www.lifepixel.com).

This is a three-frame HDR shot - there was a slight breeze so the tips of the trees came out a bit furry - the effect of slight movement between exposures.
The infra red effect really enhanced the 3D texture of this sculpture while emphasising the embossed carvings. 
Actually it looks 100% better than the one I shot in colour
Looks like a goanna staring into space.  Shooting digital infra-red is easy and produces a number of different colour and black-and-white (post-processing) options.

Fill-flash Technique

Sunset shots are hard to get - we drove up to the Broken Hill Sculpture park to watch the end of the day. Dozens of other visitors and photographers also arrived to enjoy the evening.  Here's a technique to get more out of the sort of average results many were getting last night. The problem of course is that most people are impressed by the emotion created by the sunset event - it's a beautiful time of day, very peaceful and quiet.
Pointing your camera directly at a sunset produces a dramatically underexposed result because the camera's metering reacts to the intense bright light.  Sometimes this can look good, especially if you have a good silhouette but once the sun actually sets below the horizon you are left with less colour and no tone in the your subject. One neat way to boost the shot and make your subject appear almost three dimensional is to pop a bit of fill-flash into the scene. You can do this using a small pop-up flash or a larger speedlight.

Set the camera on a tripod and in Manual (M) metering mode establish the base exposure - do this in Program mode, then copy the exposure recipe into manual mode.  A good sunset fill flash exposure is one that produces a nice, rich sky colour. 
In this example it was 1/250s because the light from the sunset was quite bright.  Most might automatically set a slower shutter speed because you are technically shooting at night, right?  No, a faster shutter underexposes the night sky and produces rich colours. 
It's important then to keep the aperture wide open, or close to wide open, so the flash can make a mark on the subject.  Most flashes are only effective at eight to ten feet with a small aperture number (i.e. f4 - 5.6).  If the aperture is set smaller (i.e. f16) it makes a huge demand on flash power - which a pop-up flash doesn't have.  If using a speedlight, firing at full to half power will exhaust the batteries fast.
As the sky gets progressively darker, raise the ISO which will also help the flash maintain its brightness.
So the lesson to be learned here is that shutter speed always controls the brightness of the ambient light while the aperture always regulates the brightness of the flash...

Sunset with no fill flash produces a nice effect but somewhat hard, black silhouettes.

The Long Road to Broken Hill

This year's three-day photo workshop in Broken Hill kicked off on October 17th.  But before we could get started we had to get there.  Five drove and one flew the mail run via Mildura.  Natalie and I drove - it's only 1200 kms.  We chose to travel via Newcastle owing to unseasonal snow (!) hampering drivers crossing the Blue Mountains.   These are a few pictures we shot in Wilcannia, a small predominantly Aboriginal settlement 950kms west of Sydney.  It's so small there's not even a decent medical service in town - the Royal Flying Doctor Service flies in three times a week to hold clinics. 
Much of the town appears to be somewhat dilapidated, and run down.  The pub on the main road through town looked like it had been under siege - many of the other houses and shops were either boarded up, for sale, or burned out.  Or a combination of all three.  Despite the fact that it is on the beautiful Darling River it comes over as being the sort of place most just drive through on the highway to Broken Hill, two hours to the West.
 However, its history is impressive. During the 1880s, Wilcannia reached its peak with a population of 3,000. It claimed 13 hotels and its own newspaper, the Western Grazier. It was one of the major Murray-Darling river ports (the third largest in New South Wales after Sydney and Morpeth) and played a vital part in the transport of goods, notably wool and wheat, in the days of the Murray-Darling paddle steamers.  At its height there were 90 steamers plying their trade on the river.  Because the river height was uncertain in those days, the banks of the river were lined with huge warehouses used to store materials for the farmers, plus of course, the wool and wheat that brought immense wealth to the inland. Now you can only see vestiges of this history with a few beautifully restored buildings like the Court House and the police station (and the gaol).

Interesting visual comment by Natalie Hitchens.
More social dilapidation in Wilcannia. 
I thought these boarded up shop fronts made good subjects for the HDR treatment
Interesting colours in Wilcannia.
