Exchangeable image file format is a standard for storing metadata such as camera, lens, and geo information in JPEG and TIFF files

Exchangeable image file format is a standard for storing metadata from digital cameras.

The tags defined in the Exif standard cover a broad spectrum:

  • Date and time information.

  • Camera settings:e camera model and make, orientation (rotation), and ISO speed, metering mode

  • Lens settings: make and model, aperture, shutter speed, focal length

  • File settings: File format, color mode

  • A thumbnail for previewing the picture

  • Descriptions

  • Copyright information.

Like EXIF, also holds meta information in image files.
