Photographer Levi Bettweiser specializes in recovering, developing and printing “found film.” Last year at an Ohio auction he came across 31 rolls of undeveloped film taken by an unnamed American soldier in WWII. He painstakingly processed as many as he could (some were water damaged) and the results are wonderful documentation of one soldier’s experience. There’s more background here, and this video about the project is fascinating.
