Color Profiles

Color profiles in photography

Bob Peters, GSFC Photo ClubSlide2

Saturation, hue, brightness, or 3 colors, most cameras use Super RGB (higher saturation than RGB), amount of red, green, blueDoes the camera sensor accurately record colorDoes the monitor accurately display color recorded by the camera Does the printer/projector accurately reproduce the color of the monitorReproducing color print especially iffy because different papers will produce different colors from the same printer and same ink.

What defines color? Slide3

“In color management, an ICC profile is a set of data that characterizes a color input or output device, or a color space, according to standards promulgated by the International Color Consortium (ICC). Profiles describe the color attributes of a particular device or viewing requirement by defining a mapping between the device source or target

color space

and a

profile connection space

(PCS)…. Mappings may be specified using tables, to which interpolation is applied, or through a series of parameters for transformations.”

The Flow Slide6

Most people prefer more saturated colors that accurate colorsPeople almost always want warmer face tones, even experienced photographers do not judge color accuratelyYou don’t always want accurate colorSlide7

Either printer software or photo editing software (Photoshop) can be used to profile printerProfiles are paper specific, type and brandPaper profiles supplied by printer are specific to printer manufacturers paper, 3rd party paper suppliers supply profiles for common printersPrinter profiles are easier to use, fewer profilesCan make custom profiles with appropriate software/hardwarePrinter ProfilesSlide8

Printer Software Manages ColorSlide9

PhotoShop manages colorSlide10

If Photoshop manages color, Printer software must be set to “no color correction” or similarIf printer software is color correction, PhotoShop must be set to “Printer Manages color”Never, ever have both printer and Photoshop manage colors!!!!!!Double ProfilesSlide11
