EXIF (Exchangeable Image File Format) is a standard for storing interchange information in image files, especially those using JPEG compression. Most digital cameras, including mobile phones, now use the EXIF format.

The format is part of the DCF standard created by JEIDA to encourage the interoperability between imaging devices. In addition to the standard EXIF fields, MetaCam also supports vendor-specific extensions from Nikon, Olympus, Canon and Casio.

This program is useful in forensics investigations.
