Ian posted up this great how-to in the MAKE Instructables group on making your own photos at home – “The goal of this instructable is to explain the cyanotype process (Cyanotype is an old monochrome photographic printing process which gives a cyan-blue print). Cyanotype is a super easy (and cheap) photo printing process that you can do at home with a few special materials. Digital pictures printed as cyanotypes make great gifts…” – Link.

This looks like the same type of print found in the “Solar Print” kits they sell in science stores. Years ago, I tried exposing this with a 35mm and an enlarger, but the exposure was so long that it melted the enlarger (It was meant for 10-second exposures, not 30-minute) … no wonder; it’s UV sensitive & the enlarger doesn’t emit that much UV. I could make contact prints in the sun from 35mm B+W negatives relatively easily, but the prints are, of course, small.
Cool how, in 12 years, the internet has spread the knowledge *and* it’s now easy to make big negatives on an ink-jet printer.
