Hi,

If you happen to be going to Yosemite between now and Sept. 30, you might want to visit the Yosemite Museum to view some Mammoth Camera photographs made by Carleton Watkins, Eadweard Muybridge, and others. There is also a big camera on display. In addition to the actual photographs hanging on the wall, there is a computer monitor showing a continuous rotation of scans of other mammoth photographs by these photographers.

Thinking about them hauling those cameras and glass plates around made my 4x5 seem pretty light.

The museum is near the Visitor's Center and the Miwok Village.
