3 Setting the Color Reproduction RangeN The range of reproducible colors is called "color space". With this camera, you can set the color space for captured images to sRGB or Adobe RGB. For normal shooting, sRGB is recommended. In Basic Zone modes, [sRGB] is set automatically. 1 Select [Color space].  Under the [z3] tab, select [Color space], then press . 2 Set the desired color space.  Select [sRGB] or [Adobe RGB], then press . Adobe RGB This color space is mainly used for commercial printing and other industrial uses. This setting is not recommended if you are not familiar with image processing, Adobe RGB, and Design rule for Camera File System 2.0 (Exif 2.21 or higher). The image will look very subdued in a sRGB computer environment and with printers not compliant to Design rule for Camera File System 2.0 (Exif 2.21 or higher). Post-processing of the image with computer software will therefore be required.  If the still photo is shot in the Adobe RGB color space, the first character in the file name will be an underscore "_".  The ICC profile is not appended. For explanations about the ICC profile, refer to the Digital Photo Professional Instruction Manual. 187
