Necessity is the mother of invention, goes the saying, and I needed a light box to look at a shoe box full of old 35mm film negatives that I have. So I made a light box with a shoe box and a glass plate.
The other little problem: it is no longer possible to run down to the pharmacy on the corner, and get prints made in an hour from 35mm film*. Besides, one would want to have scans made directly from the film, instead of prints that would have to be scanned. It seems to me the options are to use an online service for film scanning, or to invest in a film scanner that will do the trick.
*Digital photography took over film some 15 years ago (in 2003, digital cameras outsold film cameras for the first time). So I’d have to ponder whether I want to buy a film scanner to bring some of these pictures back to life.
