I used to work at Kodak... (Hehehehehe... Hehehehehehe hehe hehe) Seen enough things going on pictures that make you wonder. Whenever we got nudes in or racey stuff, they had to be reprinted because the machinery is not set up to process large areas of skin, people tend to come out white blobs so they have to re-print them with a shorter exposure so that skin looks pink.
Because you have to inspect each individual image to determine type of colour shift and exposure, you get to see some mind scarring images. I am still traumatized some 15 years on, some nights I wake up screaming and covered in sweat beads.
Like the 16 stone chocolate woman in a leotard that keeps on chasing me in my nightmares wanting me to eat her... (Fnarr Fnarr)
