The color space refers to the range of reproducible colors. 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 [2] tab, select [Color
space], then press <0>.
2
Set the desired color space.
Select [sRGB] or [Adobe RGB], then
press <0>.
This color space is mainly used for commercial printing and other
industrial uses. This setting is not recommended if you do not know
about image processing, Adobe RGB, and Design rule for Camera File
System 2.0 (Exif 2.21). The image will look very subdued in a sRGB
personal computer environment and with printers not compatible with
Design rule for Camera File System 2.0 (Exif 2.21). Post-processing of
the image with software will therefore be required.

About Adobe RGB
If the image is captured with the color space set to Adobe RGB, the file
name will start with “_MG_” (first character is an underscore).
The ICC profile is not appended. See explanations about the ICC profile
in the PDF Software Instruction Manual on the CD-ROM.
