    My new digital camera comes with Adobe RGB and sRGB options.

    In Photoshop I am set to Adobe RGB, so it makes sense to have the camera set to the same setting right? My owners manual says that Adobe RGB will create more muted colored photographs. Why? Is the sRGB more heavy handed and skew everything in a more saturated direction?

    Thanks, everyone.

    The colour gamut is larger... that is the technical answer why.

    Colour gamut is determined by the original recorder / converter of the image. Unless you're processing in RAW then it doesn't matter what photoshop is set to, it'll load the image in whatever colour gamut the camera is set to. If you open the RAW in photoshop it still doesn't matter what photoshop is set to, it's what CameraRAW is set to that matters.

    Now AdobeRGB is a larger gamut. But there are many issues with working with larger gamuts. The bulk of them are discussed here: http://www.thephotoforum.com/forum/...prophoto-colour-management-general-worth.html

    The gist of it is:
    - Colour management is a complicated workflow or it produces crap results.
    - Most can't view gamuts larger than sRGB.
    - Can't upload to the net with gamuts larger than sRGB.
    - Most can't print with gamuts larger than sRGB (some very expensive labs can, do you use them?)
    - Unless you use 16bits per pixel all the way through your workflow your results in wider gamuts will be worse than in sRGB.

    In other words, using anything wider than sRGB is a serious, serious PITA, even when you know what you're doing, and the itty-bitty benefit you might get out of it usually isn't worth it. (Maybe it's worth it for scientific experiments with colour, or perhaps it's worth it to a photog who uses super-saturated colours in their images; colours that fall outside the sRGB gamut. Of course you can only come close to that kind of large gamut with prints, and only good ones made with top-quality printers. Oh, and then there's the whole calibration and colour matching thing. What a bloody nightmare.)

    just make sure to work in the same color space as you printing. Adobe RGB gamut is capable of reading more colour.

    Actually I just got a lovely panorama printed by a local pro lab who offered a Kodak Supra metallic finish on the photos. They charged me $45 for a 32x20" print and their requirements? sRGB JPEG file or TIFF file. They do a "colourmanaged" process as well allowing ICC profiles in JPEGs for a $20 surcharge. Thanks but no thanks.

    o_O Wait, they have the software to manage ICC profiles, and the want to charge you for something that'd be done automatically anyway? Ridiculous.

    It's kinda like charging for photography. You push the button and the camera does 3/4 the work. You load the image into your computer and the software does the remaining 1/4.
