Hundreds of UFO images captured over Perth, Australia - Apr 27, 2013

Rob Hartland has taken from the veranda of his Darlington home in the Perth Hills, more than 20,000 photos of the day-time sky in the past six months and analysed them on his computer.

It began when he was taking photos of clouds to test out a new camera when he noticed a "smudge" that, when enlarged and enhanced, "had some structure to it, suggesting it could be some sort of craft in the sky".

He says since then he has identified a dozen different UFOs including round, square and saucer-shaped craft, posting the photos to his website wispyclouds.net for extra-terrestrial buffs and sceptics to ponder.

These craft are fast-moving and fly at fairly high altitude as Rob usually focus the camera on the edges of mid- to high-altitude clouds. Rob usually take a series of 20 to 30 photos on continuous shooting mode with a fraction of a second between each photo. When captured, most of the time these craft are present in only one and occasionally two of the series of 20 images. Rob usually take about 300 images at a time, especially when there are wispy high-altitude clouds. On some days there may be craft present in more than 5% of the photos, although many are too small for enhancing.
