6.5 x 8.5" Daguerreotype
Exposure: 8 seconds @ f3 (Zone VI: 12.66ev)
Development: 3:00 @ 175˚F
A failed experiment with interesting results. The plate was made on silvered glass (see instructions here). I made a few marginally successful Becquerel plates last year using silvered glass, however something about the traditional method (perhaps the heat of the Mercury?) caused much of the silver to flake off in the fixer.
