Okay kiddo, have you ever looked at a picture and thought that something looked weird or stretched? That's because something called perspective control wasn't used when taking the picture.
You see, when people take pictures or draw pictures, they want the picture to look like it does in real life. But sometimes, when you take a picture from a certain angle, things can look weird or distorted.
Perspective control helps fix this problem. It's like a special tool that people can use to make sure that the lines of buildings or objects in the picture look straight and not crooked.
Think of it like building with blocks - if you stack blocks on top of each other, they make a tower. But if you stack the blocks at an angle, the tower looks crooked! That's like what happens in pictures, but when using perspective control, it's like someone is coming in and straightening out the blocks so that the tower looks neat and perfect.
Overall, perspective control is a way to make sure that pictures look accurate and realistic, so that everyone can enjoy looking at them without feeling like things look strange.
