The color space determines the gamut of colors available for color reproduction. [sRGB] is recommended for general-purpose printing and display. With a broader gamut of colors than [sRGB], [Adobe RGB] is a better choice for professional publication and commercial printing.
The selected color space may be overwritten when pictures are opened in third-party software. NX Studio can open pictures in the color space selected on the camera.
For accurate color reproduction, Adobe RGB pictures require applications, displays, and printers that support color management.
