OK. I've read around tons that it is better to take your RAW images and convert them to Adobe RGB to edit and everything. But I seem to remember reading somewhere that you have to convert it to sRGB before you save them for the Internet. And to me that seems true because when I take my images, without converting the profile, and save them for the web, I get a darker image generally, with a bit of a bluish tint to it. So what am I doing wrong? Do I need to convert the image color profile or what? Any suggestions would be great.

Yes.
The Adobe RGB color space is larger than the SRGB space. If you don't convert before saving, your color space info just gets discarded and the (Adobe RGB) image is displayed as if it were inthe sRGB color space. There will be color and tonal shifts.
Simply convert to the sRGB space, then save for web. That should eliminate any shifts, except where colors are out-of-gamut for sRGB. To check prior to converting, use "proof colors".

Yes, you are correct about using Adobe RGB(1998) and then converting to sRGB for web use, and yes, you will notice a difference. You didnt mention it, but are you shooting Adobe RGB straight out of the camera? I dont know for sure if it comes into play with Camera RAW, as RAW is exactly that - the data straight from the camera, but if you ever needed to shoot JPEG from the camera, it would help to setup the camera to use the Adobe color space as well.

Equally important, of course, is calibrating your computer display to the same standard.

I do the same. Now, as far as calibrating my monitor, I have no idea how to do that. Other than making sure the contrast and brightness are acceptable. Any ideas on how to make sure my monitor is calibrated?

And last, but not least, what is the proper way to convert the color space from Adobe RGB to sRGB in Photoshop?

Thanks for all your help so far.

And for saving in sRGB, you can check out EddyG's tutorial at //www.dpchallenge.com/tutorial.php?TUTORIAL_ID=26
