Cyanotypes are an amazing process discovered in 1842. I have some very generous photographer friends who have been hosting an alternative photography group where my boyfriend and I have been learning some fantastic new things.
It's pretty amazing what you can do! You can also purchase "sunprint" paper which is ready to use, and all you have to do is rinse and dry after exposing. These were made with chemicals coating coldpress watercolour paper and a UV light (since it was a rainy day).
I predict I will be doing more of these in the future!
