The Making of Passage: A 2-Colour Gum Over Cyanotype Print

I'm making a two-colour gum bichromate over cyanotype print of an image I shot in Japan, back in 2001. The original was shot on 4x5 HP5 film. This print is being made with two digitised negatives. One that has been tailored for the cyanotype process, and the other for the gum bichromate process. Hold on to your hats, as it moves quickly!
