I've known all along there are differences between general photography and that shot specifically for publication, and I wanted to share an important difference I just learned about color space settings. Below is a paragraph in the guidelines I recieved from one of the largest international stockphoto agencies in the world.

"Don’t forget that we want the photos be in the Adobe RGB 1998 colorspace because it is ideal for photos that will be transformed to CMYK (cyan, magenta, yellow, black), the colorspace used in the graphic arts industry. We will apply the appropriate color profile for viewing photos in Internet, the sRGB IEC61966-2.1, as it reflects the normal characteristics of a PC monitor. Therefore, we need your photos with High Resolution and in a colorspace such as Adobe RBG 1998 and we will take care of making them look great on Internet."

Most cameras come with an sRGB default setting, and for posting to the internet or having regular prints made, this is best, but for those here who aspire to have their work used in advertising and other commercial mediums, it's best to change the color space setting to aRGB.
