Okay kiddo, have you ever watched a movie that shows real things that happened in real life? That’s called a documentary! When people make a documentary, they want to show real life events and tell a story about them.
Now, documentary mode is a way of telling that story that helps people understand what really happened. There are different ways to tell stories in documentaries, but documentary mode is special because it tries to be as truthful as possible. This means that the people who make documentaries using documentary mode try to show things as they really happened, without changing anything or adding things that didn’t really occur.
They also try to let the people who are in the documentary tell their own stories, without making things up or putting words in their mouths. They might ask people questions or let them talk about their experiences in their own words.
So, when you watch a documentary that uses documentary mode, you can trust that it is telling you the truth about what happened. Pretty cool, huh?
