sRGB or Adobe RGB...?

[Eolo]

Hello, (my english is very bad)I am a new and happy user of the 10 D, besides my Eos 3 SLR also had previously a PowerShot G3.
My question is... which are the real differences between the sRGB and Adobe RGB, I usually use the Photoshop.
Another thing, that I have noticed a certain bias from the camera to subexposed the scenes... to some of you it has passed him?

Thanks.

Mario.

The AdobeRGB color space has a wider gamut, meaning that it will describe more different colors than the sRGB color space. Because that wider gamut is being compressed into an sRGB monitor, it will appear a little flat on your screen. Use the Photoshop Windows RGB preview to restore its appearance. You can always convert it to sRGB at a later time, though you will lose some extreme color information. If you only display on the web and do not print or prepare your images for process color, then it may be best to work in sRGB all the way through.

I have found that the evaluative metering will choose an overall exposure that is a little darker than one might want for display. This is because the digital file will provide much shadow detail, but once highlights are blown out they are gone forever. Also, posterization in highlights recorded with too little density is much more visible than in the shadows. If you don't care about losing those highights and want an image that is viewable immediately, consider using center-weighted metering, or adjust the exposure compensation.

The more powerful the tool, the more you have decide what you want from it so you can channel that power appropriately.

Very clear their explanation, although I supposed that with so excellent tool (10D) it was not necessary correcting the exposure compensation manually, the worst thing is that in the display of LCD the picture is correctly exposed, I believe that it is but near to the reality to see the graph of the histogram...

Thanks..
