Many digital cameras - notably digital SLR models and high-resolution fixed-lens cameras - allow photographers to record images in the raw file format - as well as the universal JPEG setting. (Some also support TIFF file capture, but this is becoming rare.) By definition, a raw file contains the data as it is collected by the image sensor, without any subsequent processing. Raw files also contain image metadata (camera settings and other technical information), which can be viewed and used by the photographer - provided they have the right software. This is normally supplied with all cameras that support raw capture.
