Was digging up some stuff for an art club newsletter I do and came across this:
Not much time left to check it out, but for what it's worth ...The Platinum Process: Photographs from the Nineteenth to the Twenty-First Century
Now Through May 23, 2010
An exhibition of some 75 works dating from the late nineteenth century to the present, The Platinum Process showcases a selection of outstanding platinum prints drawn from the Museum’s collection. Highlights include photographs by early masters of the platinum process including Frederick H. Evans and Paul Strand, as well as works by skilled contemporary practitioners such as Lois Conner.
It's in the Perelman building, at Fairmount and Pennsylvania Avenues, across from the main museum building.
(Maybe I'll get there!)
