Hi there. I am a French physicist who came to photography through Wikipedia and who now works for the Wikimedia Foundation. See also my website (ou le site en français).

You'll also find me on Wikipedia & Wikimedia Commons.

Most of my photos are under CC-by-sa and can be found in larger resolution on Wikimedia Commons.

If a photo is copyrighted or not available in larger resolution, feel free to ask me. You can contact me by e-mail or usually find me on Freenode IRC as guillom.
