I do a lot of macro cave photography. Cave photography is a bit of a beast to tame, but macro cave photography is like a beast with two heads. And one them has a laser beam on it. It’s a challenge, but when successful it can provide a unique look at the mysterious world of caves from a completely different level.
I sometimes focus on cave contamination: the littlest things like lint on a stalagmite. It drives home the message of just how delicate and vulnerable a cave really is. Upon entering, zero impact is not an option. A cave is constantly being compromised by human access. Due to these circumstances we have the responsibility to protect them to the best of our ability.
