Self-portraits can help you learn about positioning people in a photograph. True
False

A camera's self-timer takes a picture after a certain amount of time has passed.

True
False

1.) True

The reason this is true is because adjusting the camera allows you to get an understanding of how someone else should look or how they would likely look best when photographed. It also gives an understanding of how a camera should be aimed to get the best result.

2.) True

While many cameras have this feature, most are configured to only use this feature when the photographer selects it. This feature allows the photographer to adjust the camera in case they feel something isn't quite right with it, and it also allows them to get into the picture themselves if they feel they want to.

Hope this helps you, and have fun with whatever it is you are doing with your camera.
