It wouldn't be going too far to say that the selfie is the most popular type of photo on social media. No matter where you look, you'll see plenty of people's faces really close up.
On the one hand, the selfie is good because it's fast, doesn't require a third party and no one expects it to be technically amazing. However, that also means most selfies are taken took close at odd angles with lousy lighting. It's even worse with group selfies or ones in front of spectacular backgrounds - something is going to get cut out.
The answer to this is the "selfie stick" or monopods. You put your phone or camera on the end of the stick which gives you some distance and better angle options. The higher end models are metal and collapsible like a regular camera tripod. Controls on the end of the stick make it easy to snap a pic or two.
That sounds like it should make for much better selfies, but there is a problem. Many people take their selfies at an angle that reveals the stick in the photo, and it kind of defeats the purpose.
