EXIF Data
Exchangeable Image File Format — a metadata standard that stores camera settings, date, location, and technical details within image files.
EXIF data is automatically embedded by cameras and smartphones when a photo is taken. It records settings like aperture, shutter speed, ISO, focal length, and sometimes GPS coordinates. EXIF data is useful for organizing photos by date and location, but privacy-conscious users should be aware that location data can be embedded in shared images.
