These are experiments in pseudochrome -- emulating an Autochrome-like

screen in contact with black and white film, to produce a color image. 

 

A few different "random" color screens were generated in photoshop and

printed out on an overhead transparency with a color laser printer.  Portions

of the screen were glued with rubber cement to black and white film and

exposed in camera, screen-side toward the subject.  On development, the film

yielded a weak color image! 

 

The images you see above were inverted in photoshop, with minimal color

correction to reflect how they actually look.
