[alt-photo] Re: Daguerrotypes and Herschel - a question for a photohistorian

[Tomas Sobota]

Malin,

I'm not a photohistorian, but since no one else is answering your question ...
It is my understanding that Daguerre was using strong solutions of
common salt in water to fix his daguerreotypes. Later, Herschel
advised him to use hypo.
