I've kinda been holding out with this one, as it was my first attempt at lightning photography and after a lot of bungling around and dozens of misfires, I finally managed to get a couple good shots. I was pretty chuffed with myself, I have to say.
I'm posting the shot taken a minute after (i.e. the dark one) as well for comparison. You can really see how a single bolt of electricity can light everything up, because the difference is huge.
