John, I'm not sure this is what you mean but I think solargraphs are more like "finding" a picture than "making" one. They reflect all the day to day variation and a stretch of time that will never happen again, ever. Plus temperature/humidity/clouds/fogginess/curl/shadows/wind/hail/rain/snow and a big dollop of luck. Like opening a present that you have no idea what it will be.
( I've got an album with some solargraphs at the link in my "signature" below, but these are very shhhhh hybrid, so we won't talk about them here. )
