I have a strange issue, pink whiskers on a cat. Only happened to one of the several shots taken of this cat, anyone know the reason ??? Filter was Hoya UV-Guard HMC.
Easy.... I examined your image under CMYK mode and all its hue curves.
Suggested reading: "Make ready: A Prepress Resource" and "Professional Photoshop: The Classic Guide to Color Corrections," both books by color-correction guru Dan Margulis.
