    Hey Filipe,

    Can you elaborate on how you made your plate? That looks really cool!

    I was reading an old article on Lippmann photography (here: http://books.google.com/books?id=54M...lbumen&f=false). It details how Lippmann made his silver halide emulsions, but it makes no mention of any sensitizing dyes. It also says that the plates were NOT orthochromatic, so I guess that would imply they were blue sensitive. It also stated that the exposures were extra long to account for the reds -- But how would that work then?

    In other news I was looking at dyes to panchromatize emulsion for Lippmann plates -- I know this has been kind of beaten to death on apug... Does anyone see any problems using erythrosine and methyl violet for green and red sensitization, respectively?

    Several people have said that they were going to try it. I have seen no data yet.

    OTOH, the Erythrosine works fine and I have posted data on that here.

    Great to see some results!

    Albumen plates promiss to have much better color rendition than slavich plates, I am still trying to determine the exact procedure.
    Whe I have consistent results I will post more information.

    Kind regards
    Filipe
