When I am opening my RAW images from my Canon 10D in Photoshop CS, the thumbnails at first seem clear with very good contrast... upon opening them into the adjustment screen, much of that contrast is lost, and the color seems to shift slightly. Does anyone else see this happening, and is there a cause? I'm not sure if it is just a discrepency between the thumbnail file and the actual data, or if I am using the wrong color space or what...
Thoughts???
How 'contrasty' are your RAW files initially?

The thumbnails are jpgs created by the camera, as far as I know. That will give you somewhat different color and contrast, depending on how you have the camera set up.

Mine are a little flat... RAW mean RAW... the jpgs have contrast applied to them already... thats why they look flat....

ok ok... so the jpegs are enhanced with contrast after the fact, the same way the white balance is applied... that makes sense... thx

The 10D Raw file contains an imbedded JPG. It is this file that is being viewed on the LCD of the camera and as the thumbnail of the browser. So it already has whatever camera settings you've chosen as well as white balance applied to it. Once you get into ACR with the photo, you have the various sliders to adjust exposure, contrast, saturation, etc. So you totally choose what you want from all the info available. By the way the 20D works the same way, even if you choose not to save a JPG with your RAW, it still imbeds a preview JPG in the RAW file.
Cheers,
rfs
