@joe - I really like the effect that 8mm lens has on those interiors
Here is a photo from my first visit to the Redwoods in the Oakland Hills.
It looked like the sun was red through the Redwoods, and casting an intense red light on the tops of trees in dark forest.
On the way back to my car I found this clearing and got a decent view.
It just kept going and got more red towards the end.
Handheld with my SMC - M 50mm f/2.
Taken at Burning Man 2010 during the Megatropolis Burn. I only had my K-x for about a month (bought it in late July), and used a Tamron 70-300 for most of the week. (it's dangerous changing lenses out there) Good thing I had the drive mode set to Hi or else I would have missed this shot.
