Photographer and artist Ian Ruhter has embraced old school technique by resurrecting silver collodion wet plate photography. The process, introduced in about 1850, requires the photographer to mix silver nitrate and other chemicals to form a mixture that is then used to coat a large metal plate. The surface must then be exposed within 15 minutes. Ruhter has chosen to work in a large scale, creating plates up to four feet wide. To project the subject image from the lens onto a plate of that size, Ruhter converted a truck into a giant camera. Watch the video above to see the truck in action, and to be inspired by an artist living his passion.
