Multi use Autochrome Plate Screen Contact Copy

[Mustafa Umut Sarac]

I think with this invention , everyone could produce his her autochrome at home. Read below ;

Autochrome 8x10 or larger processed antique plate could be purchased from antique dealer starting from 60 dollars or climb to few hundreds , than panchromatic emulsion side could be removed from the glass plate , than 8x10,4x5, or smaller color film could be contacted with starch colored RGB layer and with help of light , color slide film could copy this screen on its surface with all starch grains distrubution and colors..

Than all needed is a large format camera , your color slide film with autochrome screen copied on it and an black and white film .

Someone could sell these slide screens , use them multiple time with crosses .

hey--why wouldn't a very grainy color film--exposed to pure white and processed--reversal film--the white is equal RGB up close, right? it'd be much smaller, but it'd be a nice random pattern--then you can maybe enlarge that film if the color bits are too small? I mean--isn't a grey card exposed on color film made up of equal RGB?

say you want bigger RGB "grains", then magnify the straight piece of film, say 2x, 4x? 10x??? whatever is needed, on another color slide filim...then there you have it, right?
