Most social networks such as Facebook, Instagram, and Twitter remove all of this data from photos when you upload them. This presents a peculiar problem - when you click a picture of a beautiful bird perched on the windowsill in your house, your camera automatically adds the location of the picture, which could reveal your home address when you share it with others online. Most cameras and smartphones these days add basic parameters such as the mode in which the photo was taken, the shutter speed, ISO, aperture data, and sometimes even the location of the photograph. Exchangeable Image Format, also known as EXIF, is a set of data that’s attached to every image you take.
