sRGB vs Adobe1998 Color Space

    My digital Olympus C3030 takes photos in sRGB. My working color space in
    Photoshop 7 is Adobe 1998, and I get the embedded profile question when
    opening a photo file. Does it help any to convert to Adobe 1998? I
    understand sRBG color space has less range than Adobe1998. If the color
    range in sRBG file is less, how can it help to convert to Adobe1998.

  2. Are we going to have this discussion every other day?... No, it doesn't
    help converting to AdobeRGB. You do not gain anything.

  3. If you're going to print the image without cranking up the saturation,
    then there's no benefit. If you're going to turn the saturation
    way up in Photoshop, then you can get into colors in Adobe RGB
    that can't be represented in sRGB, and thus would want to convert.

    Many cameras can actually capture colors that can't be represented
    in sRGB, so increasingly they are offering options of storing images
    in Adobe RGB. Also, some just quietly settle for some color
    inaccuracy -- capturing a gamut that exceeds sRGB but saying
    that it's sRGB.

    I generally don't convert.

    I use Image->Mode->Assign profile... for that purpose. I hardly convert
    colors from one to the other profile.

    Hmmm... I'd thought that having an image in a grey-balanced color
    space was useful when removing color casts (i.e. equal values of R,G,
    and B == some kind of neutral).
    I'm self-taught on this one, though and may be very off-base...

    (Russell Williams)
    Of course it IS useful, but then all the abstract 'working' spaces like sRGB,
    AdobeRGB and the others are grey-balanced to start with so you're missing the
    point. This is one reason why Adobe switched to abstract working spaces
    instead of using the monitor profile (like in version 5), because the
    device-specific spaces like a monitor are almost never grey balanced.

    AdobeRGB has a wider gamut (more possible colors ... more crayons in the box)
    and while the original poster has already clipped his camera's colors down to
    sRGB's gamut what Russell is saying is that it's easy to increase saturation
    and add shades that are part of the AdobeRGB gamut but outside the sRGB gamut.
