Is there anything in the world cooler than volcanoes?
OK, maybe squid with laser rifles, or Formula race cars, but volcanoes still rank up in the top of "things that are totally cool."
The picture was technically almost perfect as well. Nice exposure on a notoriously difficult subject, under less-than-ideal circumstances, and what you've done with it is nice, too.
Did you do any other post besides inverting the negative? It's a 5 star either way.
