Welcome to APUG, Storyteller.
You stepped on a hornets nest at first, but now you have recovered.
I had a circa 1935 folding camera that used 120 film. It was a Certo Super Dolly with a Zeiss lens, no range finder, and an extinguishing light meter. It took 6x6 and had a mask for 645. It took some amazing photographs. This photograph was take at Union Station in Los Angeles. A 5"x5" print showed what looked like dirt on the glass panes. When I printed it 30"x30" the "dirt" turned out to be etching on the glass. The wonders of film photography. On the print the blacks are black; in the digital scan, not so much; please read line three of my signature.
