Which metadata can be stored?
Typical information that can be stored directly in the image files are date and time, focal length and aperture, exposure time and ISO value. Modern cameras and smartphones equipped with sensors can also store geographic coordinates. In total, there are now more than 100 standardised meta-data. In addition to the Exif standard, there is also so-called IPTC data. The standard developed by the International Press Telecommunications Council (IPTC) is primarily used in photojournalism and allows the storage of additional information such as copyright notice, author and description as well as further references to the contents of the photo such as keywords, details of the location, or titles.
