The color spaces we use in photography
The color spaces we use in photography
sRGB The “standard” of the web and most photo finishers. Designed in 1996 by Microsoft and HP sRGB has the smallest spectrum of colors of the primary Color Spaces. sRGB was primarily designed for the computer industry as a way to standardize colors on monitors and printers.
Adobe RGB Designed by Adobe in 1998, attempting to duplicate the spectrum of colors created by the CMYK printing process. Offers a wider range of available colors than sRGB. Adobe created Adobe RGB for the growing computer graphic arts sector, leading to a wide adoption by photographers.
ProPhoto RGB Created by Kodak and approved in 2003, ProPhoto RGB started its life out as ROMM RGB. Designed from the ground up as a Color Space designed to supplicate all the colors visible in Ektachrome slide film, ProPhoto RGB has one of the largest color gamuts out there. Designed by photo experts for photography, ProPhoto duplicates most of the humanly visible colors that occur in the real world, surpassing Adobe RGB by a long shot.
Melissa RGB Another Adobe defined Color Space, but only used inside of Lightroom. Melissa RGB is the Color Space all your RAW files are manipulated in inside Lightroom, as you cannot select another working Color Space. However on export you must select an appropriate Color Space to export to. Melissa RGB utilizes the ProPhoto color spectrum and applies the Gamma curve from sRGB, providing the best of both Color Spaces.
