A picture file format that some of the more advanced cameras have the option of using when taking photographs. In this mode the photograph is captured in a "raw"state direct from the camera's CCD so no automated processing is done by the camera. Use RAW processing software such as Capture One to view and process the file on your computer giving you complete control of properties such as exposure, colour and sharpness. This mode is preferred by enthusiast and professional photographers who tailor settings to there liking. The downside is the file is not compressed by the camera, like it is in normal jpg shooting mode so you can only shoot a small number of photos before the memory card fills up.
