This is a view inside Concourse C of the new Bangkok International Suvarnabhumi airport. It's an an interesting design, and appears to consist of sails stretched between sections containing windows.
There wasn't much colour in the original image, and I found the duotone version a little more interesting than the colour version.

When driving somewhere near Busselton, we came across this old shack, and I had to stop and take some photos.

I thought the duotone conversion and some light vignetting added to the old feel of the photo.
