A selfie is a self-portrait photograph, typically taken with a hand-held digital camera or camera phone. Selfies are often shared on social networking services such as Facebook, Instagram, or Twitter. They are usually flattering and made to appear casual. Most selfies are taken with a camera held at arm’s length or pointed at a mirror, rather than by using a self-timer.Robert Cornelius, an American pioneer in photography, produced a daguerreotype of himself in 1839 which is also one of the first photographs of a person.
