A small free command-line utility to manipulate/extract Exif data
held in jpeg pictures taken with digital cameras:

download: http://www.sentex.ca/~mwandel/jhead/jhead.exe

main page: http://www.sentex.ca/~mwandel/jhead/
"Things jhead can extract from an Exif jpeg file:
-Time and date picture was taken
-Camera make and model
-Integral low-res Exif thumbnail
-Shutter speed
-Camera F-stop number
-Flash used (yes/no)
-Distance camera was focused at
-Focal length and calculate 35 mm equivalent focal length
-Image resolution
-GPS info, if stored in image

Things jhead can modify in an exif jpeg file:
-Up-right images according to rotation tag using jpegtran
-Set or relative adjust internal exif timestamps
-Re-name or date stamp fils according to exif timestamp
-Transfer exif headers between images
-Replace thumbnails inside Exif headers
-Edit jpeg comments (but not the Exif comments)
-Delete exif or comment sections from jpeg images"

usage guide: http://www.sentex.ca/~mwandel/jhead/usage.html
"Jhead is a command line driven program for manipulating the non-image
parts of Exif flavour JPEG files that most digital cameras produce.
Windows/Mac users: Jhead has no Graphical User Interface. Clicking on
it with the mouse from Windows or Mac OS-X won't do anything for you
- you have to use it from the Command prompt (or DOS prompt under
Win95/98/Me)"

I've been playing with that recently. It works well and I know o
nothing else that does what it does
