In reply to the discussion: Shroud of Turin [View all]I'd love to know if the person who made this image went the next step and made a positive print. I don't recall the gentleman's name--I read about this in an actual book in an actual library, presently closed for the weekend--but the head of the art dept. at a South African university made a reasonable approximation of the shroud image on sensitized linen using a toolshed sized camera oscura and a full-body plaster cast of a man the same size and build as the subject on the shroud. The main problem he encountered was the long exposure time required. I'll try to have the reference for you Monday if you'd like to follow up.

Not to say you're wrong again, scottie, but the term here would be brunaille, not grisaille.

The only time I'm surrounded by blather is when you go off on one of your usual tangents.

You know, if you would clear your mind of preconceived notions every so often, you'll do better.

There is zero evidence for photographic processes before the 19th century.

Unfortunately that is not visible to me due to the way DU's ignore feature works.
