The story is told directly by a character (I) who is one of its central figures, someone who is present in all the key scenes. We experience the story as the narrator experiences (or experienced) it, and are privy to the narrator’s intimate thoughts. We are limited, however, by what the narrator knows or doesn’t know. If there is information the narrator has but doesn’t share with us, there’s a good chance we’ll feel betrayed.
Example: I watched the woman walk down the street. Why did she wear red boots?
The story is told by a voice that appears to be speaking to another character or to the reader (you). While the viewpoint can function much like first person, it is more difficult to convey the narrator’s thoughts and feelings, especially if they’re nothing like the reader’s thoughts and feelings. Unlike first person, second person can make you feel distanced from a narrator (which can be both a pro and a con). When used sparingly, this can be a surprising and effect POV.
Example: You watched the woman walk down the street. Why did she wear red boots, you wonder.
Third Person Limited
The story is told in third person (she or he) and features a character whose thoughts are known to us. Overall, this is the least intrusive viewpoint because it can be nearly invisible to the reader. Like first person, third person limited can show us a character’s intimate thoughts, but it also keeps us within the bounds of what the main character knows. Generally, a third person limited narrator can withhold information more easily than a first person narrator.
Example: She watched the woman walk down the street. Why did the woman wear red boots, she wondered.
Third Person Omniscient Involved
The story is told from a viewpoint that may shift throughout the story. The narrator may show us the internal thoughts of any of the characters as well as his/her own. Often, the narrator’s voice is stronger than that of any of the characters, and we get the sense that the narrator is leading us through the story, showing us what we need to know. This viewpoint often keeps us at a distance from the characters, but it can be an effective way of underlining the themes and ideas of a story.
Example: Darleen watched the woman walk down the street. Why did the woman wear red boots, Darleen wondered.
Marla looked down at her red boots and looked up at the woman who stared at her. What right does she have to question my choices? She'd never wear green and yellow together.
Third Person Omniscient Detached
The story is told from a viewpoint that is uninvolved in the story. We see only the actions of the characters but are never privy to their internal thoughts. We observe the events of the story and are forced to guess at the characters’ motivations . As in fairy tales, characters are defined by their actions. There is no psychology and we must draw our own conclusions about the story.
Example: Darleen looked at the woman wearing red boots. The woman looks back at her, lifts her chin in the air and walks faster.
