Colorsync, Adobe RGB, 10D, PB Display

[carnagex2000]

Im using OSX 10.2.6 on a 12" Powerbook, and ive read that shooting in Adobe RGB has a wider color space then the standard RGB parameter. Now how do i set up my mac/photoshop to use Adobe RGB. Ive already changed my Image Capture to Embed a ColorSync Profile with Adobe RGB (1998) as the Profile. Now in colorsync, under cameras, I selected Canon EOS 10D, and it shows the Current Profile is Adobe RGB, but I also have my wifes camera on it (Nikon Coolpix 2100) but it does not let you select Adobe RGB, so I have it set to Generic RGB. (will i have a problem having different color workspaces?) Also in Photoshop under Photoshop/Color Settings, should I set the Settings to Colorsync Workflow, or another setting? Also if i choose Colorsync Workflow, under working spaces, I can choose from a list of choices, which one do i want?

Monitor RGB-Adobe RGB (1998)

Colorsyc RGB-Generic RGB Profile

Adobe RGB (1998)

Apple RGB

Colormatch RGB

sRGB IEC61966-2.1

Also, in Displays (system Prefs) under Color. Which Display should I pick ? Do I keep the default Color LCD or should I select AdobeRGB (1998) Also will this cause color problems when using non-AdobeRGB profiles (from my wifes nikon 2100- which uses Generic RGB profiles)

The best is to use colorsync workflow!
You must set
Monitor RGB-XXXXXX to the name given when you calibrate your monitor with adobe gamma, this is the profile of your monitor! It's used by the OS and by photoshop (must be the same).

Working space- yes adobe 1998 is wider than sRGB but the difference could not be seen on a display as the display profile is near the sRGB space, some differences could occurs in the printing process (conversion to output space).
So if you want to use it set your working space to adobe 1998.

If your 10d is set to adobe 1998 it will enter the working space asis.

Consumer camera usually are sRGB space compliant.
So for your other camera you must assign (embed) an sRGB profile then covert to your working space. There is no benefit to convert from a smaller space to a bigger space except that if you're working in standard in adobe RGB it's better to keep all your image in this work space untill output processing.

Output processing.
For the WEB: You should convert to sRGB before publishing for the WEB (or to another profile "display like") otherwise your colors will fade. (browser are not profile aware).

For on line shop: usually you must convert to sRGB, amost all on line shop are calibrated for sRGB, in some case (pro shop) you could convert to a specific printer profile.

For direct printing: assign the right profile to your output device.
