First I just upgraded to CS 4 from CS 3 and am thinking I must be overlooking some preference. Let's say I bring a RAW capture set to sRGB into Photoshop then under the edit menu convert the file to sRGB to me no change should happen however when i do this I am getting a very weird color shift. Even if I was converting an Adobe RGB image to an sRGB space I wouldn't expect nor have I ever seen such a dramatic shift in the colors.
Color Management Policies: Preserve Embedded Profiles
Coversion Options: Adobe Ace Engine,
Intent: Relative Colorimetric
Checked: use Black point Compensation
Use Dither (8-bit)
Compensate for Scene-referred profiles
Any suggestions or insights what I should look at to see if everything is set up correctly? thanks jeff
As I understand it, a RAW capture cannot be "set to sRGB" (or any color space). When you set your camera to sRGB, it means that if you convert the image to JPG in the camera, the resulting JPG will use sRGB. So, a RAW does not have an embedded profile to preserve. When you open a RAW, PS will use the color space you select under Working Spaces:RGB, which should be Adobe RGB or, even better, ProPhoto RGB.
Let's say you have it set for Adobe RGB. When you open a RAW, PS translates the data in the RAW into colors in the Adobe RGB space. THis space is quite a bit larger (contains more colors) than sRGB, so when you convert to sRGB some of the colors change.
Hope this helps,
