Why we pose
According to Nikon's research 71% of us pose at least some of the time in front of the camera. Of course, the main reason for striking a pose is wanting to look good.
The second most popular reason for posing is the instant gratification of being able to see a picture straight away on a camera and the third reason is people knowing that the pictures will end up on social networking sites.
Anyone who's found that picture of their dodgy hair cut / disatrous night out / enormous zit posted all over Facebook won't want a repeat.
