Viewpoints and Switching between them

Omniscient is the all-knowing narration, mentioning what this or that character is thinking or feeling any time the author pleases. Characters are kept at an arm-length and equal. The reader finds it harder to identify with one character and to get involved. Thankfully we have many viewpoints to choose from. Readers can live the adventures along with the characters by hitching a ride on their shoulder or even from within their minds.
