Sorry everyone,
I know I’m bringing up a rather digital topic, but the story I’ve heard is just too crazy.
There’s a way to immortalise photos in concrete, and apparently it works like this: a photo is digitally converted into greyscale, and using that data, a film of varying thickness is sprayed with a retarder (which is something that slows down the setting of the concrete). Concrete is then poured onto this film and treated like exposed aggregate concrete, and the different layer depths create different shades of grey.
So if photographic paper ever runs out, we’ll just go back to chiselling in stone like the ancient Romans.
Regards, Achim

Sorry about that, too, because when I look at the architectural masterpieces of our forefathers, I can’t help but suspect that a silver print like that would certainly last much longer, even without being tinted.
Well, maybe there’ll be concrete toners soon?

Best regards
