Third-person limited POV shows readers only what happens around that person—usually the protagonist or heroic figure. If you start that way, you stay that way. (As I mentioned in an earlier post, you can switch to first person if you start a new scene. That's not common, but it's acceptable.)
You are always inside the perspective and emotions of one person. For most modern writing, you don't jump into another person's head within the scene. Everything that happens comes from that singular POV. There are usually frequent uses of "he thought," or "he said," from the narrator's POV.
I want to stress that readers see, think, and feel only what the main character experiences. There are no shifts to another character’s thoughts or emotions.
Limited third-person POV is easy to read
and the most widely accepted POV.
