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