Because everything is in focus the camera has not picked out anything leaving it to the eye. However if you choose f5.6 the hole is bigger and your subject should be in focus but not all of the background. So the higher the f-stop the smaller the hole. That also means less light. In old photography you would need a lot of light for f-22. So there was always a balance between the light needed and the effect. In a romantic scene you may want only the Close-Up: the actress's eyes to be in focus. You need f-1.6 or f 2. But because there is a lot of light you might need a filter for the lens to "think" there is less light. And then you can set the f-stop to get exactly the focus effect you want.
