Jhead Description

Jhead is a command line driven Exif header parser and manipulator. 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.Jhead project 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. Many projects, including PHP, have reused code from this utility.Things jhead can extract from an Exif jpeg file:? Integral low-res Exif thumbnail? Shutter speed? Camera F-stop number?
