I just got a gallery on alternatephotography.com and there are
five orotone glass plates that I recently finished .These do not scan well because
they lose the three dimensional effect of light passing through the positive image
and reflecting back from the gold leaf on the back of the second glass plate.

I am interested in finding who first made orotone plates and the history
of the process. The only information that I find is about Curtis and he renamed
the process to Curtis Type.
Best regards,
