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 .
