A selfie is a self-portrait photograph, typically taken with a digital camera or camera phone held in the hand or supported by a selfie stick. Selfies are often shared on social networking services such as Facebook, Instagram and 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. A selfie stick can be used to position the camera farther away from the subject, allowing the camera to see more around them. 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. Wikipedia
