What is EXIF metadata?
Every time a camera or phone takes a photo, it embeds a surprising amount of invisible information inside the file itself: the exact device model, the date and time of the shot, technical parameters (aperture, ISO, shutter speed) and, often, the precise GPS coordinates of where the photo was taken. This is called EXIF metadata. Files can also contain IPTC blocks (authorship and rights credits) and XMP (Adobe's extensible editing metadata).
