I'm always happy to do media for anything science or sceptic in nature. My sceptical website is located at www.scepticsbook.com

I am not selling my photos commercially yet, but will do on a case by case basis until such time as there is a demand. If you want to buy one, let me know.
If you're interested in using any of these for any other purpose, please get in touch with me. Most of my pics are CC for not-for-profits and we can negotiate on commercial use.
