Yes. Phillip. Thanks for the advice.
I just bought "Coming Into Focus", last week, and it haves a chapter on
daguerreotypes and the bequerel process. Doesn´t this process need more time
when exposing the plate?. Is there any other difference, rather than the
long developing times and the less sensibility of the plate?. Maybe some
color change?.
Thanks again for your help!.

Sincerely,
Agustin Barrutia.
