For almost every year since 1973, John Running has made a river trip down the Colorado River through the Grand Canyon. On these trips, he often rows a raft but he always takes pictures. In the 1990s, he photographed with Polaroid's Sepia film. In his photo album "River Notes, October 2-16 1995, May 16-June1 1996," he writes:
"Polaroid manufactures a Special Edition Sepia Film which has beautiful, almost antique looking, warm brown tones. To make pictures using it, I bought an old range finder Crown Graphic 4x5 press camera, fitted with a Polaroid back. I used the combination to document my river trip. The Colorado River takes its name from its muddy red color, to my amazement the river’s color matched the warm hue of the sepia film."
