EXIF, IPTC and other Metada

Information stored within image files

EXIF : Techinal data from the producer of the image (Digital Camera, on shooting conditions)

IPTC : Edited by the user (Title, keywords, copyright ...)

Used by photo galerie generators like ... "Galerie"

Photoshop allows you to store text metadata within your image files, by using the File / File Info command. That set of fields is IPTC/NAA compatible, and it has become a standard for the handling and storing of image metadata, specially by news agencies. On the other hand, EXIF data is information that digital cameras store in the image file, about the camera itself and its shooting values.
