This photo is not, as it might first appear, taken out in the countryside. It's actually about a 10 minute walk from where I work and if I had moved the camera just a few degrees to the left you'd have seen a great big office building. The camera lies by omission.
This particular pond is on my morning walk route and one of the things I noticed was how still the water was. Particularly early in the morning when the sun is low it tends to act as an excellent mirror.
