I recently purchased a Canon 40D digital SLR. It allows you to select the color space you want assigned to your image files -- I selected RGB. When you open the ColorSync utility there's a tab for devices and a list that includes 'camera'.

How to I add my DSLR so it shows up in ColorSync?

I keep hacking away at trying to have a color managed workflow. This stuff ain't easy, in my view.

    Forget about the ColorSync Utility - you don't need to go there.

    Your camera allows you to choose between 2 colour spaces: sRGB and AdobeRGB.

    sRGB is the most commomly used one and recommended. Most printing services – including Apple's – assume sRGB, and if you deliver anything else you'll most likely be dissapointed.
    You should only ever choose AdobeRGB, if you have very good reasons to do so and are well-versed in the issues of colour management; otherwise you'd better avoid it.

    Furthermore the colour space selection in your camera only matters if you shoot JPEGs. If you shoot RAW, it's irrelevant, as RAW files aren't confined to any colour space.

    By the way, you shouldn't be 'hacking around' regarding colour management. It's a very complex area and you're likely doing more harm than good without a solid understanding of how it all works

    Thanks Martin.

    The lack of clearly written documentation about color management is one of my pet peeves. I'm an amateur photog and have found it maddening to wrestle this subject matter area to the ground and be able to get good results printing at home, or with a photo service.

    What you say about sRGB vs RGB is news.
    I'm taking a night class in digital printing at the New England School of photography. I'll print your response and see if the instructor and class agree with your take.

    Often recommended with perhaps more information than you ever wanted: *Real World Color Management* by Bruce Fraser.
    Color Management Info is a good online resource.

    My recommendation to stick with sRGB rather than AdobeRGB in the beginning is based not only on my own experiences, but mostly feedback in user forums such as this.

    Somewhere people may have read or heard that "AdobeRGB is what the pros use", so they just adopt that without thinking. Truth is though that most commercial printing services assume sRGB and even ignore any colour profiles in images – frustration guaranteed.

    It's a different story when you print at home in a closed workflow where you can control every stage of the process.

    It all starts with calibrating your screen. And if you want to make the most of your images, you will probably start shooting RAW, if you're not doing so already.

    Before Snow Leopard, I was able to choose which colour profile was imbedded when importing a file via image capture by opening colorsync utility and specifying the profile.

    However, since installing snow leopard, it appears that this has been reset to CameraRGB. Even if I set it to an sRGB profile in color sync, if I unplug my camera and replug, it resets to default of CameraRGB. This is an not an issue if the camera is set to sRGB (as CameraRGB is Apple's version of sRGB and is pretty close), but if the camera is set to adobeRGB, it still imbeds the cameraRGB profile - how do you get the choice to stick?

    This is a ColorSync issue? Probably best to post on the Using Mac OsX forum here:
