Jhead - Extracts digital camera settings from the Exif files

'Jhead' extracts digital camera settings from Exif format files. It handles the various ways these can be expressed, and displays them as F-stop, shutter speed, etc. It also reduces the size of JPEGs without loss of information by deleting integral thumbnails that cameras put into the Exif header.

It extracts 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.
