A camera raw file contains unprocessed image data from a camera's sensor along with metadata. It is a digital negative that provides more flexibility than JPEGs. RAW files are larger but retain all image data, allowing for more control over processing. Common RAW formats include Canon CR2 and Nikon NEF. The digital negative format DNG is an open standard supported by Adobe. Camera RAW workflow involves importing, editing, and exporting RAW files using software like Adobe Camera RAW or Lightroom.
