Tintype photos, as the name implies, were photos with the image on a metal surface, rather than on glass or paper.
This short film reveals the process and makes me nostalgic for a time where image making relied heavily on process and the element of surprise.
Some of my fondest memories of art school were of being in the dark room developing film and sloshing chemicals around in a tray. Nowadays, tethering a digital camera to computer does not have the same romanticism but perhaps in 30 years I may feel different!
