Chuck, that blobby confidence required layers work in Pshop. No stone unturned!
To your question, I don’t think these necessitate large cameras, though the extra detail doesn’t hurt. Andrew Long’s placed a bunch of Robert Frank nodes on the map on flickr, for what it’s worth.
Didn’t Timothy O’Sullivan put people in the photos for scale? My thought was that these could be more than a placing, for scale, that the human subject was as important as the landscape and both would combine to create something new.
