Why are SelectaColor, Pyrofoto and classic processes often called “room light” processes?
Because unlike emulsions, they do not require a darkroom and can be handled under subdued room light. They include SelectaColor and other alternative processes. They are contact-printed under a full-size negative, using bright lamps or sunlight. Back to top Some processes like SelectaColor, Pyrofoto, FA-1 sensitizer and blueprint require a full-size negative for contact-printing. I’d like to make such a negative from a color print. How do I go about it? Formerly, full size negative transparencies could only be made photographically, but now they can be made digitally with any inkjet or laser printer, or photo-copier. See “Transparencies” on the Products page. Back to top I’d like to transfer a color print to metal. Can I do it with SelectaColor? Color prints consist of dyes. Dyes are transparent, to allow colors to add together to make “process” color. Example, blue on yellow gives green. Because they are transparent, dyes show up only against a white background (color print) or when l
