According Wikipedia, his first photographs about Yosemite Park were taken with a Kodak Brownie about 1916, however from 1917 he was taken photographs at the area using different cameras and lenses, it's sure he was using glass plates in 1927 (f.e.

The glass plates size are 6.5"x8.5", this is the negative size for the Korona View Camera mentioned above (from my own brief research).
