Back in the 70s an ABBA ALBUM jacket would be as big as a 1800s film square. I am trying to understand how you go from light being absorbed or refracted from an original source, being early photography, to copying that same film to larger pieces of paper through chemical process.
It's the same way the light got on to the tiny film, just played in reverse.
Essentially you put the "developed film" (where it is stopped from absorbing or being effected by light through chemical treatment) in a enlarger and shine light through it on to a larger photo-sensitive piece of paper and then put this paper in a chemical bath to lock it's photo-reactive state.
Wow - thank you for that. Great explanation!
I posted an old picture of myself recently that was taken by a friend who was into photography and had his own dark room. I have a collection of 5x7s and 8x10s from the photo shoot he did. He wanted to use one animal as his subject (all in black and white) and asked if he could photograph my dog. He brought me a sheet of tiny little pictures and told me to select the ones I wanted and let him know what size. For all I knew he using some sort of voodoo magic to make it happen.
