Taupenot’s Process
From George Eastman House : Notes On Photographs
A dry collodion-albumen process introduced in 1855 by Dr. J. M. Taupenot. The collodion plate was prepared as in the tannin process above, but the washed plate was then coated with albumen and dried. The dry plate was then dipped into an acidified silver solution and washed and dried again. Development was identical as with the tannin plate.[1]
