I finally got my scanner plugged into something that will use it. Heres a couple of frames from my 4x5. The first is the humongous flywheel of a huge pump, there were several in the pump room, and I have no idea what it's for. The second is of some of the valves and smaller pumps in the other half of the room, an equal mystery. A fascinating place. My Acros wasn't used to its full advantage, the first had movement problems and the second was a bit thin looking. I'll have to make more trips until I quit messing up my shots and get it right.
