I've got a 20D and can set the color space in the camera. I understand the differences between Adobe and sRGB and was also under the impression that when shooting raw it didn't matter.

The color space is listed in the EXIF data. Does this have any effect other than to tell the raw converter which mode the camera was in?

It doesn't. Any color profile or parameters settings only apply to the embedded JPEG (for in camera LCD review - and used as a preview image by some software).

No - with a RAW file, you choose your color space when you convert to TIFF or JPEG.

What are you using to look at the RAW Exif? When I look at mine with Photoshop Elements 3, the RAW files say "Untagged RGB".

I am evaluating IdImager as a cataloging program and ran across a directory where I was testing the camera with the color spaces, raw and jpeg. I opened one of the images shot in Adobe and on the bottom of the screen the program tells me that the Image ICM Profile was Adobe and the Current ICM Profile was sRGB. I click on a tab that says image details and it shows me the IPTC info (blank) and then the technical (EXIF) data listing the camera, date, shutter, and color space.

Sounds like he's looking at the JPG, not the RAW file properties.

With my G5 the EXIF for a CRW file says nothing about color space, but there is another section called Camera RAW and there it says Camera Profile = ACR2.4
