Pima County Public Library: Cyanotypes

Cyanotype is a 19th Century photographic process still in use today. Prints can be made using objects placed on photosensitive paper and the power of the sun. If you’ve ever seen a blueprint, you’ve seen a cyanotype! Join us to learn more about cyanotypes and create some prints of your own to take home! Bring a few small objects to try printing (hand size or smaller, flat is better) or choose from our collection of interesting objects at the library.
