taken in Lewis and Clark Cavern, Montana. I discovered before arrival that they did not permit tripods inside the cave. So, I chose one really sharp and fast and sort-of wide lens to take: the Canon 35 f/1.4 L. It's pretty sharp and very fast in low-light situations. This shot is hand-held with ISO 800, f/2.8. Caves are pretty fun!
That's pretty cool being purple like that. You have other shots?
I have a shot a couple of caves, it's nice when you can use a tripod, but a couple of times I just had to shoot fast. For me, having VR on a lens was the greatest thing as it gets a couple of extra stops there.
