Film.  Remember that? This collection of images were all photographed on film and cross processed,
or processed with a chemistry intended for a different type of film. This causes color negative film to turn
into color positive film, you know like slides.  Likewise, color slide film (positive) becomes color negative film, where the images look reversed.
Confusing?   Well let's just say it did take a lot of testing to get positive results!

Like a blast from the past, some film when cross processed also tend to make things look older
or retro, sort of like an old Kodachrome slide would look with age.
