This is from Deer Cave in Gunung Mulu national park Malaysia. It's a blend of three exposures. It wasn't easy to do for me but I really like the result.
Thanks everyone! I was trying to keep it natural and was worrying about contrast between trees and cave. Nice to hear most of you think I did it "right".
I had fourth image for highlights in trees but decided to leave it unused and blow out some highlights because i think it looks better like that. And guess what? I didn't have tripod. :|
