Gamon Ranges in South Australia. This image was taken at the end of a prolonged drought

The following photos are a random selection taken in various states of Australia. Most of the time they are taken using the available daylight en-route to somewhere, or at a campsite.

The following images look at the way light behaves as it passes through air of differing densities on its way to our eyes. Mirages occur when light is refracted away from its straight path, thus the contents of that light look out of place. Most Mirages are inferior, that is the effect is seen below the actual horizon. These are usually associated with heat in the air. Sometimes but much less often we can see superior Mirages where the effect is above the actual horizon. The center image below is an example of this, and these are associated with cold air. In this case the inverted sand dune was refracted along the earths curvature from over the horizon. Once this Mirage was dissipated by the warming air the horizon was dead flat as can be seen about one third the way up in this image
