I noticed in my camera menu (Canon 50D) that I have to choice of "Colour Space" - either sRGB or Adobe RGB.

The camera defaults to sRGB

When I process RAW images, I've been taught to set Camera RAW to process in Adobe RGB, which makes me wonder if I should be shooting in that colour space to start with.

Actually, I have absolutely no idea what I'm talking about so can someone help please.

If you're shooting RAW it doesn't make any difference, the colour space is only assigned when the shot is converted to another format (JPEG, TIFF, PSD, etc). This setting only affects the colour space used for JPEG's. If you're shooting JPEG's and going to print from them set the colour space to Adobe RGB, if only displaying on the web use sRGB

FWIW I set my camera to Adobe RGB just in case I ever get the urge to shoot JPEGs.

There are many short tutorials on when to use what and what the difference is.
This one
http://www.cambridgeincolour.com/tutorials/sRGB-AdobeRGB1998.htm

explains the difference in an easy way. If you want to make high quality prints it is best to work in AdobeRGB but there are some traps in the work flow from capturing to print. For example, most photo printing places won't actually supports anything but sRGB, your monitor can't display all the ADOBE range so you have to guess a bit etc.

Before you start to shoot AdobeRGB, do some tests all the way to print and make sure you get what you think so you don't make a mistake wit those photos you will never be able to recreate. sRGB is really an easier work flow from start to finish (less surprises). For underwater shots though, use RAW so you have maximum freedom to change whitebalance etc. afterwards, introducing as little artifacts as possible.

Finally, in order to really make use of AdobeRGB, you need a good printer and you need to be able to calibrate your monitor so you have a calibrated workflow from start to end.

Adobe RGB comes up as under saturated when displayed on the web so use SGRB for posting on flickr etc
