EXIF

EXIF Back in the days when Optima typewriters were clacking in Stasi offices in the GDR and Underwoods typed out top-secret reports in Secret Service headquarters, there were specialists who could identify a typewriter from its typeface. If they got a used ribbon, they could find out what documents had been typed with the ribbon and how long they were. And every typewriter—human combination had an unmistakeable fingerprint. But those were specialists. These days, our cameras save much more sensible data in the pictures, and we share those with the world via Internet. The EXIF metadata standard is widely accepted, pretty much every camena uses it. There are useful things like exposure and ISO data saved, those can definitely help improve one's photo- graphy skills, but there's also data than one might not want to share with the world. At least not in every photo: Modern cameras with GPS modules also save the geographical location into the metadata, so everyone knows where you took the picture of that pyramid - or your car/house/dog... The serial number of your camera is saved into the EXII information, so you don't need the experts previously mentioned anymore, but include this sensitive data into your image. And EXIF is only an example, there are many more metadata standards, for antoher example, Word documents save your changes and often your full name and the computer's name. Actually, almost every file you save has some information in it - the experts are obsolete and replaced by your own files, programs and devices. maschinengeschrieben.blogspot.com Optima Elite This awesome post was brought to you by the mighty Typosphere
