JCE Classroom Activity
Blueprint Photography by the Cyanotype Process
Glen D. Lawrence and Stuart Fishelson
Long Island University, Brooklyn, NY 11201
Cover
September 1999
Vol. 76 No. 9
p. 1216A
Abstract
This activity demonstrates catalysis of chemical reactions by ultraviolet (UV) light using one of the earliest photographic processes, the cyanotype process. The photographic paper for cyanotype photography is easily prepared in the classroom, giving students the opportunity to see that the photographic image is a result of chemical treatment of ordinary drawing paper. The sensitized paper can be handled in visible light. The image is produced by exposure to UV light from direct sunlight or fluorescent black lights.
Supplement
The activity sheet is available as a pdf file, which can be accessed using Acrobat Reader.
