Re: Hand collotype in process


I am not sure if this is appropriate question or not.

Does anyone know where would be a great website to share the video file of collotype process on internet? The clip is about 360MB. Is YouTube the best way to go?

Look at the link Tom posted:  http://www.phototypie.net
Even with failed high school French from half a century ago I figured
out a lot by going through the long set of photos and discription on
the site. My question, is why do they use glass? A less fragile sub
would seem a lot less trouble. Is there something about glass that
creates a better bond or do they flash it from the back to help bond
it? It seems that a metal plate could be grained the same way just as
zinc plates are for lithography.
