Perhaps tiff-like. https://secure.wikimedia.org/wikipedia/en/wiki/Raw_image_format "Providing a detailed and concise description of the content of raw files is highly problematic. There is no single raw format; formats can be similar or radically different. Different manufacturers use their own proprietary and typically undocumented formats, which are collectively known as raw format. Often they also change the format from one camera model to the next. Several major camera manufacturers, including Nikon, Canon and Sony, encrypt portions of the file in an attempt to prevent third-party tools from accessing them.[2]" A real mess. '.raw' is used (among others) by Panasonic and Leica. Not clear if .raw is the same for both. -- Terry Jan Reedy
