In the current (autumn 2011) issue of Photoworks there is an artical on Kenji Hirasawa whose uses a thermal imaging camera to capture portraits. A few months back I visited Jodrell Bank where they have a thermal imaging camera. I took this picture of myself and my partner by photoing the display from the camera.
I used the fold out screen so that the camera was not in the shot. What captured my interest was the difference in temperature. I'm much warmer than Katya and she has a conspicuously cold nose having been outside! It's an interesting way of looking at people that I've only seen before in airports in China (when the bird flue was scare was on).
