An introduction to colour negative printing using the RA4 process This workshops introduces the principles and practice of analogue colour negative printing using subtractive colour printing and the RA4 machine process. Overview of colour theory using cyan, magenta and yellow filter systems Colour printing rules: Colour cast: Too magenta - add magenta Too yellow - add yellow Too cyan - subtract yellow and magenta in equal parts Too Red - add yellow and magenta in equal parts Too Green - subtract magenta Too Blue – subtract yellow When adding filtration, the expoure time needs to be adjusted by +/-10% to compensate for filter density per 10 points of filtration. |
