Main Points (Effusive praise be given to Tanya B)
Third Person Limited is in one person’s head in a given scene and you do not show things that the character can not see.
Be careful of viewpoint errors – you will knock the reader out of the narrative.
You can do a large cast because the reader is constantly reminded of the character’s viewpoint and name.
Third limited is better for setting a scene in an immediate nature without the “me, me, me” of the first person viewpoint.
It can give an epic scope.
It is best at hiding things because you can just not show a viewpoint that knows.
You can do “throw-away viewpoints”: one scene from a random character’s viewpoint.
You can show discord between what a character says, what he thinks and what the narrative says.
Third is more immersive into a setting of a story, while first is better for showing a great character.
Picking between the first and third viewpoints is fundamental to your book.
Description should be filtered through the viewpoint lens of the character’s eyes.
