This technique has been given a hashtag #wetcyan, and has become known as the wet cyanotype process. Essentially, the process is breaking all the rules of the traditional cyanotype process, where I'm deliberately introducing moisture and using long exposure times, up to 48 hours or even more.

I've been asked how long I left the prints developing in the water. I'd say at least 30 minutes but I've left them in there for longer mainly because I forgot about them.
