Jhead - Extracts digital camera settings from the Exif files

Jhead is a command line driven 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, etc. It is also able to reduce the size of digital camera JPEGs without loss of information, by deleting integral thumbnails that digital cameras put into the Exif header. If you need to add Exif support to a program, this is a simple program to cut and paste from.

The program can extract (among other information): an integral low-res Exif thumbnail, shutter speed, F-stop number, Flash used (yes/no), Focus distance (not all digital cameras store this element), focal length (most zoom cameras store their zoomed-to focal length), equivalent 35mm focal length (calculated from focal length, CCD size, and CCD resolution), image resolution, time and date of picture, and camera make and model.
