Some people love to be in front of the camera. They might be famous models or just ordinary people who like to take pictures of themselves (or by others) with their cell phones.
Other people prefer to behind the camera. They might be great photographers or simply good with their cell phones.
The difference in personalities of these two type of people is quite significant. It’s important not to assume these two types have the same motivations or triggers.
It’s also important to realize there is a third type who doesn’t want to be in front of the camera or even behind it. These people prefer to be completely removed from any type of publicity (creating it or promoting it). It’s easy to ignore these people but you do so at your own peril. Don’t mistake quiet for uninterested, they just might have a different perspective or interest then you.
Have a great day!
