I discovered Eric Pare's light tube light painting photography featuring Kim Henry a couple of years ago and was completely blown away by what they were creating. Now, I've done some light painting stuff in my time, and continue to do so, but never to the extent of what these two are doing. It's absolutely stunning.
When you look at what they create, you think, "oh man, there's no way I'd ever be able to do that!", but you know what, according to this tutorial from Eric Pare, it looks pretty straight forward (minus the travelling to stunning, exotic locations that is...he he.)
