Exposure bracketing

Exposure bracketing is when a camera takes multiple pictures of the same thing, but each picture has a slightly different level of brightness. Imagine you're painting a picture of a sunny day at the beach. You want to make sure you capture all the colors accurately, but the bright sun might make some parts of the picture too bright and wash out the colors. So, you decide to take three pictures: one that's a little darker than you think you need, one that's just right, and one that's a little brighter than you think you need. This way, you'll have three different options to choose from that capture the colors and brightness of the scene in slightly different ways.
Exposure bracketing is like doing this with a camera. The camera takes multiple pictures, each with a different level of brightness (or exposure), so that you can choose the best one later. This technique is helpful in situations where the lighting is difficult to control or change, like when you're taking pictures outside on a sunny day or in a dimly lit room. By taking multiple pictures with slightly different exposures, you increase the chances of getting at least one that's just right.
