In April 2013 (the 12th, 13th & 14th), David Puntel, of the
Central Valley Project, will be conducting a weekend workshop in Salt, Albumen, and Cyanotypie Printing at the
Volkshochschule Friedrichshain-Kreuzberg ("Experimentelle SW-Fotografie"). Contact the school directly for registration (don't delay, the October 2012 class was fully enrolled).
