Jhead is a command line utility for extracting digital camera settings from the EXIF format files used by many digital cameras. It handles the various confusing ways these can be expressed, and displays them as F-stop, shutter speed, and more. It is also able to reduce the size of digital camera JPEG files without loss of information, by deleting thumbnails that digital cameras put into the EXIF header.
