I’m not sure exactly how the idea formed, but it was with my friend, Jake Kedzierski.  We’d each shoot a couple rolls of film, rewind them, trade rolls, and shoot again, not knowing what the other person shot.  That would create some random double exposures.  Since Jake lives in upstate New York, and me, Denver, we mailed the rolls with sharpie marks indicating where to line up the first frame.  I posted some of these awhile back here. These are the ones I forgot about.  I really liked the results and Jake and I talked about doing some more.  Color would be really interesting!
