In the Darkroom: Photographic Processes before the Digital Age  Exhibition at the National Gallery of Art, through March 14.  (review by Tom Hady)

The National Gallery has assembled a fascinating exhibition of old methods of photographic reproduction; from Daguerreotypes, tintypes, albumin prints, gum dichromate prints, carbon prints, carbro prints, bromoils and more.  Having "worked in the dark" for more than fifty years, I'd heard of most of these, but had never (knowingly) seen examples of many.  They are a fascinating lesson in the many facets of our craft.  I found examples of the same negative by Alfred Stiglitz, printed in three different media, especially interesting.  Present and former darkroom workers will find the exhibit fascinating, and those who came to photography only in the digital age will learn a great deal about the history of their medium.  The exhibit is in the West Building, ground floor, galleries 30-32.
