A selfie (/ˈsɛlfi/) is a self-portrait digital photograph, typically taken with a digital camera or smartphone, which may be held in the hand or supported by a selfie stick. Selfies are often shared on social media, via social networking services such as Facebook, Twitter, Snapchat, and Instagram.
They are often casual in nature (or made to appear casual). "Selfie" typically refers to self-portrait photos taken with the camera held at arm's length, as opposed to those taken by using a self-timer or remote. A selfie, however, may include multiple subjects. As long as the photo is being taken by one of the subjects featured, it is considered a selfie.
