I received a old box of glass plates from Perutz. It contains a number of unused glass plates. I would like to use it.
I know how to use plan film on 4x5 inch. There you can recognize the emulsion side by the notches at the top right.
It's a panchromatic film, I can't watch in red safe light
But how do I know what the emulsion side is with a glass plate?
