When a CCD captures an image on a digital camera, a wide range of light information is gathered. On a normal camera, the exposure setting is chosen by an algorithim for a "best" image and the rest of the exposure information is lost. In RAW format, all that information is kept and you can set the exposure and LOTS of other parameters after the fact on the computer. It should be said that this is not pixel manipulation such as just doing Brightness/Constrast adjustments but as stated, the same type of work a photographer would use in a darkroom to create and image from film. Big files but unbeliveably cool to work with.

Thanks guys I understand now... I played a little with the software that came with the camera... Now I see the diff between changing those exposure parameters on the RAW pic and changing brightness using say Photoshop...
