Before you accuse me of being too abstract, allow me to explain. In computing nomenclature, the term metadata denotes data that describes other data. Boy, things have changed with taking simple snapshots in the intervening 30 or so years, haven't they? Metadata and Exif I also was selective about who saw my photos because you could hold them in your hand, and they could be shared only with people whom I was physically near or to whom I mailed the prints in an envelope.įinally, the thought of taking risky or provocative pictures was out because I was sure that the images would get flagged by the photo processor at my local pharmacy. The raw truth of the matter is that I didn't take any "selfies" with my old Disc camera among other reasons, the camera's focal length was too long.
