Daguereotype: Questions diverses

[Aleniderg]

Sorry, but I haven't understood where you silvering the copper plate 4x5' and the thickness of the silver, 10-20-30 micron ?
Thank you to all

[jf Cholley]

10 microns are sufficient and cost cheaper... 20 microns allows to erase several times the plate of silver to begin again it in case of error (Provence machine translation)

Yes, ok, but where (the address) you silvering the 4x5' copper plate ?
Thank you
