The Science Of Selfies

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 Instagram, Snapchat, and Tumblr. They are often casual, and are typically taken either with a camera held at arm's length or in a mirror.
Social media scientist Dan Zarrella used a dataset of more than 160,000 Instagram images tagged with #selfie to study the science of selfies and what leads to more (or fewer) likes.
