How is a C print created?

[Ellis Vener]

Could you be a little more specific?

[Sean Donnelly]

The 'C' is for chromogenic, meaning that the color dyes are chemically formed in the emulsion during color development, much like color negative film. As Dan wrote, it is a negative-working process used to print from a color negative. Today's 'C' prints are made by the RA-4 process.

An 'R' (reversal) print is also chromogenic, but reversal-processed to give a positive print directly from a positive slide or transparency.

For concise introduction to color processes, I recommend Henry Horenstein's Color Photography: A Working Manual.
