This is a very attractive image. It's easy to get lost on the swirls. I am wondering what was back-breaking about it though. Did you have to dangle by the foot from a bridge to make it?
Thanks blaxton, original_ann---about the aches: I was leaning over the whole time---peering through a ground glass that was tilted away from me. (Really need a prism for the Hassie.) And watching very, very closely as things happened mostly way too quickly to do anything useful...
Confess I hadn't considered the dangling technique...
Here's another water study from that same series---same film (Kodak 160NC).
