I have been experimenting with cyanotypes.
The cyanotype process predates photography and is a kind of sun print, using simple chemistry to sensitize paper and the sun’s UV radiation to expose the image. The prints are made as contact prints.
This took 2+ hours to expose in my kitchen windowbox, propped at a 45° angle: light in October at the 47th parallel not so strong.
This is yesterday’s effort: this was more than an hour, but not angled at all. And some shade crept into the mix as well.
The King of All Makers loaned me the chemistry to do this, in hopes I’ll write up a HOWTO. Watch this space.
