Image MetaData:-
Picture metadata is used to convey additional information about the picture, the scene, the camera, the people in the picture, or other related data.There are Some Standards used in Digital cameras to store metadata in Image.These common Standards are following:-
1.EXIF (Exchangeable Image File Format)

Mostly Digital cameras use the EXIF Standard to store Metadata .For example Nokia Handset use EXIF Format to store Meta data. EXIF (Exchangeable Image File Format) is the most commonly used type of metadata. EXIF is a standard controlled by the Japan Electronics and Information Technologies Industries Association (JEITA). Exif is a variation of JPEG.
