Metadata: Details related to the camera and the settings for each image stored are known as metadata. Metadata can be accessed by clicking on the Properties section of the image in most editing and image viewing software programs.
Metadata includes the camera brand/model, lens type, F-stop (aperture), exposure time (shutter speed), ISO, exposure bias (exposure compensation), focal length of the lens, metering mode, flash mode, white balance, file name, image type (eg: RAW or JPEG), creation date and file size (KB, MB, etc).
Metadata can be used by photographers to maintain better control of their images and for entering more specific information as necessary.
