Trichromy

Trichromies... Arista II black and white film... three separate pictures taken with filters to represent the Red, Green, and Blue layers of a normal color photo... RGB... I guess this is how Technicolor worked, black and white film with filters, or so I read. When overlaid in photoshop and screened you get a color image in which anything which has changed or moved becomes a neon ghost of sorts. I want to do more of these in the future, but it can be a tedious process.
