[OM] Mercury

[Rich Lahrson]

Hi,

     What about the very first photographers, the daguerretypits?  The
process required
the plate to be treated with a mercuric compound fume.  Doesn't sound
healthy.  Those
still using the process and/or demonstrating it, take the necessary
precautions today.

                                                                Cheers,


Rich Lahrson
