Should I specify Adobe RGB when my camera has this setting?

I have the Digital Rebel and been using the default parameter for color space. Since I use Photoshop to edit my picts, should I set both color spaces to Adobe RGB? Is there an intrinsic advantage to using Adobe RGB which as I understand is a larger gamut than sRGB.
Thanks.

Yes, and the larger gamut is the reason.

If it has a larger gamut, how come it ends up looking less full of colour when viewed on a monitor? Is it because there is now more colours that fall outside the monitors range, or because the colours being more spread out dont have as much impact that a more compressed/limited range would have?

On my monitor I can see a visual and notable difference when I choose sRGB and then Adobe RGB, then back again…. I’m also interested in whether there is a difference in resultant print depending on which is assigned/converted to the file to be printed, or is this all down to the software used to print and how it interpritates/converts to the final printed gamut/profile?

The gamut is larger, but not by a huge margin:

Whether you should use the Adobe space or sRGB depends. For example, if all your images are going to be viewed on sRGB monitors, then at some point all that "extra information" will have to be "removed". Would you like the camera to do this at image collection time (at zero time cost to you), or would you like to do it post-exposure in PhotoSlop?

OK, so if only a monitor is involved, then you suggest using sRGB in-camera setting; what about outputting to an Epson Photo inkjet as the prime use of the colour space, again from PS. (Given the difficulties of colour matching between monitor and printer). Further thoughts on this challenging topic??
