I learned a lot today about colour management (post may induce sleep)

Ah, okay, things start to make a bit more sense.

1st, change your color management policies. Try "convert to the working space." If it's an AdobeRGB file going into AdobeRGB workspace, this will have no effect and the profile will be preserved. But if it's an Adobe file going into sRGB, you definitely want to change it. Click the little boxes to "ask when opening" and you'll get a little pop-up reminder that this is happening. Then let photoshop convert it to the working space.

Remember, the goal is to have your images look the same (except for out-of-gamut colors, of course) in any color-managed application, and for non-color managed apps (or sRGB devices like most inkjets), a simple conversion to sRGB is all that should be necessary.

Which brings up Irma's workflow: If you are converting from RAW, you should NOT need to assign a profile to your images. The profile should already be embedded, and then you simply convert to your working space if it's different. That means all of this:

Quote:~~Assign profile ........................ Adobe RGB

~~Convert to profile:

Profile ..................................... Adobe RGB

is unnecessary.

However, with some DSLRs (like the 10D), even if you shoot a JPEG in Adobe RGB, the profile does not get embedded by the camera. (Though sRGB does.) In that case, it IS necessary to assign the Adobe RGB profile to your jpeg, and then convert to the working space if necessary. Again, for converted RAW files this should not be necessary.

And yes, Irma, "Image Ready" is the application that converts PS files to the web, but it's very tightly integrated and you never really need to open Image Ready separately. The "save for web" window in PS is really an Image Ready screen that opens within PS.
