Hi
this is my first post and i have just got my first DSLR, the new canon 450D.
after having a good read of the instruction manual i have had a play around with the above. i have read in various photo mags that adobe uses a wider colour range, esp in the green area. my question is, when i took a photo of something green the sRGB shot looked 100% correct whereas the adobe looked totally different to the 'real' green object in front of me! have i totally misunderstood how it works?

It's a lot more complicated than you might think. It depends on whether you view your AdobeRGB image in a program or web browser that knows about AdobeRGB. If the viewing application doesn't handle colours properly, it ignores the embedded profile and assumes everything to be sRGB. If that happens, the full range of colours is truncated and the image appears quite muted in terms of saturation, almost pastel-like compared to an sRGB image.
If your image is for the Web, most Web browsers are clueless when it comes to colour management so AdobeRGB will always look flat. Note that even if your viewing application is colour-managed and can support AdobeRGB or other colour spaces, your screen may not. There is where a monitor profile comes in. All these profiles re-map image colours to match the devices on which they are being viewed.
So, if you are new to photography and new to colour-management or produce images essentially for the Web, stick to sRGB. If you feel that you want the wider gamut of AdobeRGB then use colour-managed applications like Photoshop, use a profile for your monitor (buy a calibration device) and use ICC profiles with your printer/paper/ink combo. To be honest, many images fit an sRGB colour space just fine and Adobe RGB is best avoided if you are starting out even if the photo mags say it's the best thing since sliced bread.

Thanks for the quick reply Lounge Lizard!
i only viewed the picture on the camera not on the PC as yet. i agree, until i understand a bit more (i have just started a C&G course) i will keep to the sRGB...

I think possibly, the main problem with using AdobeRGB is when your monitor is incapable of displaying it. You will have real problems getting prints that match what you see in front of you. But they may be a better match for what you saw when you took the photograph if everything else is colour matched for AdobeRGB (camera, printer etc.). But when you need to make adjustments on screen the problems begin.
If your monitor is AdobeRGB capable, then it works well and gives great tonal range.
Sticking to sRGB will still give you adequate results though.
