Cyanotypes are meant to be left in direct sun, not in a camera but by making educated guesses and common sense experimentation I am able to get very interesting images in my Rolleicord and Mamiya M645. I recently started using a pre treated paper called nature print paper, find the amazon link in description which gives much better results and I can actually rinse them. here is a Flickr album with the improved images.
