Image Basics

Exchangeable Image File Format (EXIF)

Almost all digital cameras save JPEG files with EXIF (Exchangeable Image File) data. Camera settings and scene information are recorded by the camera into the image file. Examples of stored information are shutter speed, date and time a photo was taken, focal length, exposure compensation, metering pattern and if a flash was used.
