EXIF data in JPG image

    How do I convince PS 6.0.1 to reveal EXIF data hiding in a JPG image?

    Using "Irfanview" (a freeware program) I get all sorts of info about
    digital camera settings and suchlike.

    Also, Irfanview tells me the image is in sRGB color space while PS
    complains: "RGB document doesn't have an embedded color profile"!?

    Could "freeware" be more powerful than "expensiveware"? ;-)
    All you Linux groupies do resist the urge to jump in... ;-)

    TIA!

  2. Photoshop 7 can. Photoshop 6 can't.
    Irfanview probably looks at the EXIF color space header. Photoshop 6
    doesn't look at that header. It's only looking for embedded profiles.
    It seems that your image doesn't have an embedded profile.

    Photoshop 7 looks for embedded profiles and if it doesn't find that,
    it looks at the EXIF color space header instead.

    Thanks very much Thomas! Mystery solved.

    BTW, I was talking about images from my digital camera. I guess I'll
    just have to enter the color profile by hand.

  4. Yes, if you have a profile that describes the cameras color space
    that is. (Most consumer digital cameras are sRGB devices).

    I can recommend Photoshop 7. It's a nice feature that you can read
    EXIF information directly in Photoshop and you can also keep the
    EXIF information in the image when you save it (not if you save with
    'Save for Web' though).

    You can read more about Photoshop 7 and EXIF colors spaces or/and
    profiles here: <http://www.computer-darkroom.com/ps7-colour/ps7_1.htm>.

    That's what Irfanview revealed too, so sRGB it is!

    BTW, what do you think, should I set my monitor (notebook LCD) also at
    sRGB or Adobe RGB which, I gather, has a wider gamut encompassing
    sRGB?
    I'm still wrestling with Photoshop 6 (I've only been playing with it
    for a few weeks) and all the options (most of which are also a
    mystery) are quite overwhelming. I'm learning lots and since all this
    is for personal use only, I can't really justify an upgrade at this
    time.

    I haven't had the time to dissect the files with my binary editor yet,
    but I may just throw together a quick-and-dirty program to "retrofit"
    missing EXIF data. It should be simple enough.
    Thanks! Will do!

  6. You would be better off with a profile describing your monitors
    color space instead of using sRGB or Adobe RGB for instance.
    Sooner or later you'll probably also discover that a notebook
    LCD monitor isn't always the best choice. Colors shifts depending
    on which angle you're looking at it, and the gamut of a notebook
    LCD is often much smaller than the gamut of a good CRT-monitor.
    (That's my opinion at least).
