Glass physautotype of halftone image made from a
collodion plate by Mark Osterman taken in Ireland.

Physautotype (in French, physautotypie) was a pre-Daguerreian
photographic process, invented by Joseph Nicéphore Niépce and
Louis Mandé Daguerre in 1832, in which images were produced
with the use of lavender dissolved in alcohol and revealed in
turpentine. No historic examples of this process survived.

This is an effort to resurrect the dead. This plate was crafted
as part of a workshop at the George Eastman House International
Museum of Photography and Film in Rochester,NY.
