What do you shoot with? Are these always on a tripod?
I think every frame I've ever shot in my life has been on a tripod. I come from a large-format world, 4x5 and 8x10, but these are all digital. It's much easier to set up a digital camera in front of these things. I actually prefer a live-view point-and-shoot camera, because you see what you get. So instead of shooting through, say, 4x5, where I have a ground glass and it's upside-down backwards and I have a loop on it and a red filter, with live-view I shoot more in monochrome mode, without using a viewfinder. And I worked out a zone system for me that emulates what I'm looking at. I started this project with the Sony [Cyber-shot DSC-] R1, a terrific camera. But I realized that wasn't the tool that was giving me the greatest flexibility out in the field, so I switched to the Canon EOS 5D Mark II. I carry a couple of those.
