Photography in the 1632 Universe: Part 2: Touching the Rainbow
Color Imagery The sine qua non for color photography is a panchromatic film—that is, one sensitive to the entire visible spectrum. Chances are that it will not be equally sensitive to all wavelengths, and that can be corrected by filtration of the more...

More complex (and hopefully more effective) encryption is possible with the aid of machines: dedicated mechanical and electromechanical devices, mechanical, electronic (and fluidic) calculators; and programmed electronic (and fluidic) computers. Mechanical...
