This, apparently. Now I wish I could say “Hurricane Sandy developed this guy’s film,” or some such punched-up header, but as whimsically dream-like as these images are, that likely isn’t the case. Their seemingly random development patterns could have been the result of floodwaters oxidixing the Kodachrome (or whatever brand equivalent) prints, true. But that’d be a stretch–the chances of water alone developing “any silver-based film, especially color film, and especially especially slide color film,” Reddit user brie-otch writes, are pretty slim. More likely the photos were already developed, leaving Sandy’s waters to warp the photos into gauzy, water-colored vestiges of their former selves.
