What kind of information can be obtained from a digital image

Question

I have seen in picasa that we can find the details of camera and date at which an image is taken. I want to know what kind of other information's can be find out using a digital image. Do you know any tools which can be used for this purpose?

Answer 1

EXIF Tags contain additional information about the image: Wikipedia "Exchangeable image file format"

It really depends on the image and camera the image was taken with, but the most common fields include: Date, Manufacturer, Model, Orientation, Compression, Flash info, GPS-Info (newer/better cameras) and much more.

There are various tools for reading EXIF data: - The simplest of all may be the Windows Explorer itself (Right click on the image and you can read all EXIF Tags) - More sophisticated programs like the Adobe Suite can also be used to read EXIF Data.
