Today at Prof. Fritzel-Shows' class of "Expressive Photography" I had my first ever exposure (pardon the pun :-)) to cyanotypes, produced by coating paper with a solution of ferric ammonium citrate and potassium ferricyanide. This coating is sensitive to UV light and can be used to create a contact print with a negative. I used 4x6 "negatives" created on an Epson printer from digital files. These cyanotypes required exposures of more than 10 minutes. I enhanced the blue a little on the computer as a couple of then could have used a longer exposure. This is a lot of fun, as it is "wet" and experimental.
