Alternative Process Images

I've recently started exploring alternative, traditional processes for creating prints. These processes generally rely on contact printing a negative on art paper sensitised with particular chemical and then exposed to UV light to produce an image. Negatives are produced by "inverting" digital images to form a negative and then printing them onto clear film to form the negative to contact print.

The blue images are Cyanotype and the monochrome images are Platinum prints

Thanks to Seamus Ryan for helping me through the alternative processing maze!
