No big deal. I get a message that asks what to do with each shot. Your Photoshop has its own groovy way of dealing with color. According to Scott Kelby in The Photoshop Book for Digital Photographers, the best color setting is Adobe RGB. Photoshop comes pre-set with a different color setting. It appears your camera does, too.

a google search about color profiles should take you to hours worth of fun (and by fun, i mean not fun at all) reading. Or you could just check the box that says "don't show me this again" :)

Thats the thing though, the setting is Adobe RGB but it uses the embedded profile on the pic instead. I only have an option to say ok to use the embedded. I want to use the Adobe RGB.

I am sure you can change the color space used by your camera to Adobe RGB.

Also, you can assign different profiles after the image has been opened. Image / Mode/ Assign Profile

In your color setting options (EDIT>COLORSETTINGS) either change your selection to "monitor" or keep Adobe 1998 but tell it to not ask about file mismatches, just convert.

BTW, 1998 is best for printing, but not for monitor viewing.

I believe you can shoot in Adobe RGB with the 10D, but if your images were shot in sRGB, then just leave them there and don't worry about it. You'll gain little by converting to a profile with a wider color gamut if the information wasn't there to begin with, and the image will essentially be in sRGB when you post to DPC anyway.

nice on spydr, sorted.

1. Don't assign profiles for images with embedded profiles.
If an image has an embedded profile, do not using Image/Mode/Assign Profile to assign a different profile, unless you really, really know what it implies.

2. Don't convert from small to large color spaces. (Esp. for 8-bit input)
Converting a JPEG from sRGB to Adobe (1998) is, as scalvert has indicated, probably a bad idea. I believe it's worse than "gain[ing] little", but it largely depends on how much editing you'll do (and how extreme it is). Also, some slightly larger spaces are probably good candidates as target spaces in sRGB conversion (because they're better for editing).

3. Edit in the appropriately-sized color space for your image bit-depth..
(Related to 2 above): Arguably, Adobe RGB is too large a space for much editing when it comes to JPEGs (i.e. editing an 8-bit image in a color space that's "too wide" leads to image degradation faster with much/extreme editing). Again, as scalvert indicates, chances are, all your destination output devices (including web) will have a smaller gamut anyway, so the big advantage for Adobe RGB is retaining original color fidelity (as much as possible with the JPEG), not necessarily extreme editing.

However, Adobe RGB is sort of the Clydesdale of working spaces, so if your image comes in with it as the embedded profile, leave it there (but don't forget to convert to sRGB when uploading to the web/dpc). I'm not sure why spydr believes it's better for printing unless he's repurposing it for something for which it's not intended. I assume he means his results with printing have been best with it, but that's another issue altogether.
