Wide shot

In the wide shot, the subject takes up the full frame. The subjects base is usually at the bottom of frame and its top at the top of the frame. Obviously the subject doesn't take up the whole width and height of the frame, since this is as close as we can get without losing any part of it. The small amount of room above and below the subject can be thought of as safety room — you don't want to be cutting the top of the head off. It would also look uncomfortable if his feet and head were exactly at the top and bottom of frame. Long and extreme long shots are often also referred to as wide shot as the frame is often wide in these shots too.

 Example of a wide shot:

This wide shot is used here to have all of the subject visible in the frame but with lots of background still visible. This means that the audience can still see the subject in good detail while still being able to see some of a location. The audience can see all the details they need which keeps them focused and interested.
