Looking back now, I do sorta wish I had taken more pictures in the early days of Disneyland. But even the 12 exposure rolls of film and their developing costs were rather expensive back then. Today, folks can shoot a couple of hundred digital photos in one day for next to nothing, and still be able to view and share them. Back then...that would have cost a fortune with a chemical emulsion film camera and all the related processing and printing.
For the first several years of shooting pictures at Disneyland, we had some sort of Kodak Brownie camera that used 120 film. This was roll film that had really wide film with a yellow backing on it, that you had to thread into your camera yourself. You had to "roll" the film after each exposure or you'd take another photo on top of the previous for what was called a "double-exposure." Ruined a lot of good photos forgetting to advance the film before taking another! You advanced the film by rolling a little wheel that turned the axle the film was threaded into. When the picture number printed on the back of the yellow light-protecting backing appeared in a little round red-tinted window on the back of the camera...you knew the film was positioned in a safe place to take another photo. When you were "out of pictures", you had to advance the wheel all the way until the end of the film ran off the feeding spool, and then you carefully opened the back of the camera and licking a special little tab at the end that had gummy adhesive on it, you glued that tab tight against the yellow backing, to make sure the film wouldn't unravel off the spool exposing the film to light and ruining your pictures. All this you had to do in a semi-dark place (never outdoors in daylight) to keep "light-leaks" at a minimum. What fun!
When the first "Instamatic" camera came out with with its pre-threaded, pre-loaded film in a sealed cartridge all ready to drop-in to your camera...wow...we thought we had really entered the space-age!
