I have an exhibition of a small number of images running in Winchester, in the foyer of the Everyman Cinema a.k.a. 'The Screen'. These are up until the end of December, so if you want to see these printed large then that's where they're at. It should be noted that printed large is nothing like what you see on a computer screen
(click the image for a decent-sized version)
1. Trees and Shadows on St. Catherine's Hill

2. Hockley Railway Viaduct, Winchester

...plus some others from my recent efforts. All on my website.
One more, not from this exhibition since it didn't make the printing deadline but it shows the sort of stuff I'm doing these days:
3. Guns Now Silent
(First World War Graves at Royal Victoria Hospital)

Opinions always welcome!

It looks like you are getting the hang of the IR thing...

This body has an 830nm IR-passing filter installed in front of the sensor in place of the normal IR-blocking filter. This means that the images produced by the sensor are black and white right out of the camera, using a manual white balance setting taken from sunlit grass. No filter is required on the lens, and daytime exposures are typically 1/90th at f/6.7 ISO 200 with the Sigma, a stop or so faster with the kit lens.
First some pictures of the body:



These are examples of images taken on this body:


You can see other examples of IR images on my 500px page or my own website linked below.
Shutter count is high, at just under 64k. The body comes with the original box, manual, strap, eyepiece cover, the rubber cover for the grip connector and charger. Due to a mix-up with batteries the OEM battery in it is actually the one from a Samsung GX20, i.e. from the Samsung-branded version. I can add a spare non-OEM battery.
The body is currently in debug mode so that a purchaser can easily adjust the AF in IR. Full instructions will be provided.
The kit 18-55 works well and the AF on this body is set to work properly with that lens. The Sigma 10-20 also works well and gives infinity focus at the infinity mark. Other lenses will vary, please ask.
I believe that ACS charge well over £300 to convert a Pentax so I'm asking £450 for this body.
This is the best time of year to do IR photography, so don't delay!

I don't notice any metal on metal rattling with the L plate. Won't it be the same with the Sun Sniper fixing? It is a metal ring that you're connecting the strap's karabiner to.
I ordered the L-plate mentioned above, but what arrived was a round fixing with a non-rotating semi-circular ring. So I'm not yet equipped...

The Fwdc209b.bin file is the one that you put on the SD card for the camera to load from. You don't put it in a directory, you put it on the card (i.e. the root directory).
Then you power up as in steps 4 and 5:
4. Turn the camera power on while pressing the MENU button.
5. "NOW LOADING" appears in the LCD monitor, and will change to the
"PROGRAM UPDATE". At the bottom of the LCD monitor,
CURRENT VERSION 1.00/1.01/1.10
UPDATE VERSION 1.11
will be displayed.
So at what point does it depart from that sequence?

Looking at the shot later I thought I'd have another go, and I knew the exact time I had to be there. So I turned up just before the appointed time - and waited an hour for the sunbeam to get to its appointed place.
The camera had been on GMT all the time, so the EXIF showed 12:00 and the clock time for the shot was actually 13:00...
That's the shot used for my avatar by the way - there's a slot of a few minutes where it gets that lighting.

These are nice Richard, even the toning suits them.
I think the last is my pick of the three, the long shadows leading towards the sun, of which I instantly thought of the White light that were all supposed to see when we pass over, although these poor souls passed over long ago.
Superb shot.
