Chirnside Woolshed, at Werribee Open Range Zoo. Here's a quick description of taking and processing an infrared photograph. Infrared is the band of colours that we cannot see just beyond normal red. Before they are placed into cameras, sensors can record the infrared colours. To ensure that we get natural looking photographs, camera makers build an infrared filter into the camera that blocks out most, but not quite all of the infrared colours. If you then attach a filter to the front of your camera that ONLY lets through infrared light, and you take a long exposure, you will end up with a photograph that shows the small amount of infrared light that gets through their IR blocking.
Your picture then looks very red in colour. But there is a spread of wavelengths in the picture. To make it more interesting to look at you adjust it in a photo editing program. I adjusted the wavelengths so that the bluestone in the Woolshed was mostly black. This left the sky a sepia colour, and it showed that the vegetation is very reflective in infrared wavelengths: the grass is a bit more reflective than the gum trees (which moved in the wind during 20 second exposure). You can also see that there is a bit of vegetation on the roof (lichen, moss?).
