About prints, she had them done. In fact the film shows she had a preference for semi-gloss paper. It is on the instructions on the receipts she kept.
She did have a darkroom once for a few years or so. That came on the BBC documentary, which was very good. The BBC doc also shows some of her prints that belong to another collector.
P.S. The cinema I went to is digital and it was a small room. There were about 20 or less people.
Before the screening started there were a few of them on their iphones, ipads and so on.
After the "film" ended I bet some went straight to Ebay to find some Rolleiflex!
I hope they do!
