EXIF stands for Exchangeable Image File Format.
EXIF data is commonly stored as part of the images ( usually JPEG ) captured by most modern digital cameras.
Why is it useful ?
The usefulness comes from the detailed information stored alongside the original image, for example the
exact time and date, which camera model was used to take the picture; even things like the flash settings
and white balance are typical pieces if
information stored.
How can I find out this EXIF information
Easy, if you are runnning Windows XP then simply hovering them mouse on the picture or right clicking
and choosing properties will show you all the data. You can also use a package like PhotoShop or PaintShop Pro.
Tip: Make sure when you save or copy your images taken with a digital camera that if the application
asks you to copy EXIF data too, say yes; otherwise all the valuable information in the image will be lost. Also be wary of
some applications simply removing the EXIF data from your JPEGs without your knowledge ( usually when
resizing or modifying the image! )
