O'Reilly has an interesting article on retrieving and analysing the metadata stored on your digital photographs.
I wasn’t aware of this, but when your digital camera takes a shot, data such as time, shutter speed, aperture, focal length, and ISO are written to the file header. This information can be then examined within image editing applications such as Photoshop 7 or iPhoto.
Analysis of this data will help us take better pictures, but there is plenty of potential in this technology. Soon GPS-equipped cameras will be able to record positioning co-ordinates to the image metadata file, that could later be translated into locations when browsed with the image editor.
