Nikon D80 on auto mode and either my 18-55 or 70-200 zoom lens (don't remember which off the top of my head as I used both). I do remember having to stand in a stream and half-lay sideways, half-crouch on the stream bank while some of the roots from that tree where jabbing me in the ribs. Not sure if I created a new yoga position or a new form of torture with that position.
But I was really amazed at how well it came out considering what I had to go through to take it. Basically, God was good to me and I got lucky.
Cheers.
