A selfie (/ˈsɛlfi/) is a self-portrait type image, typically taken with a smartphone which may be held in the hand or supported by a selfie stick. Selfies are often shared on 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. In 1839, Robert Cornelius, an American pioneer in photography, produced a daguerreotype of himself which ended up as one of the first photographs of a person. Because the process was slow he was able to uncover the lens, run into the shot for a minute or more, and then replace the lens cap. He recorded on the back 'The first light picture ever taken. 1839.' A copy of his 'first selfie' graces his tombstone at Laurel Hill Cemetery in Philadelphia, Pennsylvania. In 1900, the debut of the portable Kodak Brownie box camera led to photographic self-portraiture becoming a more widespread technique. The method was usually by mirror and stabilizing the camera either on a nearby object or on a tripod while framing via a viewfinder at the top of the box. Grand Duchess Anastasia Nikolaevna of Russia, at the age of 13, was one of the first teenagers to take her own picture using a mirror to send to a friend in 1914. In the letter that accompanied the photograph, she wrote, 'I took this picture of myself looking at the mirror. It was very hard as my hands were trembling.'.mw-parser-output .tmulti .thumbinner{display:flex;flex-direction:column}.mw-parser-output .tmulti .trow{display:flex;flex-direction:row;clear:left;flex-wrap:wrap;width:100%;box-sizing:border-box}.mw-parser-output .tmulti .tsingle{margin:1px;float:left}.mw-parser-output .tmulti .theader{clear:both;font-weight:bold;text-align:center;align-self:center;background-color:transparent;width:100%}.mw-parser-output .tmulti .thumbcaption{text-align:left;background-color:transparent}.mw-parser-output .tmulti .text-align-left{text-align:left}.mw-parser-output .tmulti .text-align-right{text-align:right}.mw-parser-output .tmulti .text-align-center{text-align:center}@media all and (max-width:720px){.mw-parser-output .tmulti .thumbinner{width:100%!important;box-sizing:border-box;max-width:none!important;align-items:center}.mw-parser-output .tmulti .trow{justify-content:center}.mw-parser-output .tmulti .tsingle{float:none!important;max-width:100%!important;box-sizing:border-box;text-align:center}.mw-parser-output .tmulti .thumbcaption{text-align:center}} During the 1970s, photographic self-portraiture flourished when affordable instant cameras birthed a new medium of self-expression, capturing uncharacteristically personal insight into otherwise conservative individuals and allowing amateurs to learn photography with immediate results. This practice transitioned naturally across to digital cameras as they supplanted film cameras around the turn of the millennium. On 13 September 2002, the first known use of the word selfie in any paper or electronic medium appeared in an Australian internet forum – Karl Kruszelnicki's 'Dr Karl Self-Serve Science Forum' – in a post by Nathan Hope. Although Hope later dismissed the notion that he coined the term, describing it as 'something that was just common slang at the time, used to describe a picture of yourself', he wrote the following:
