Cyanotypes and Photography | Morning of Chemistry 2012
Although most photography is based on the photochemistry of silver halide salts, the photo-chemical reduction of the iron in an Fe(III) salt to Fe(II) can be coupled with the non-photochemical reaction of Fe(II) with the ferricyanide ion as an alternative method to produce an image. This process is known as the cyanotype or blue print process. To learn more go to http://www.flinnsci.com Be sure to subscribe and check out more videos!
