the ambrotype

 

 

I just learned how to do Wet-Plate Collodion.
The ambrotype was introduced in the 1850s. It is a positive photograph on glass 

made by a variant of the wet plate collodion process - 

each picture is a unique original. 

I learned about mixing chemicals (the silver bath, the collodion, the varnish), 

exposure and development ... and all that in english language. 

Thank you Dave @ Central Valley Project 

Photographic Studio - this was such a great workshop!
