What makes a good exposure

To emphasize motion on the other hand, use a long exposure time. That will make the motion turn into a blur. The subject can be moving against a static backdrop a blurry stream of water, lines of light from car headlights in night photos, etc. In our example, during the exposure the lens smoothly copied the motion of the car. Usually ISO only comes into play when you want to use a shorter time than you can achieve even with a fully open aperture.

The classic example is photographing a static object in dim light without a tripod. Another common reason for using a high ISO is because you want to freeze motion in a photo, and so you need to use a shorter exposure time than even the widest aperture could give you.

Using a high ISO does have its price. Your pictures will have reduced quality from a technical standpoint.

They will have digital noise and reduced dynamic range. That feature is exposure bracketing. It makes the camera expose the same picture multiple times, with the exposure shifted by a set amount each time. Some cameras let you create a longer series of shots and let you choose by how many EV the shots will differ.

In the era of shooting to film, this function was very useful for even just the goal of getting one good shot. In situations where it was hard to get a good exposure, the photographer created multiple exposure variants, and when developing the film, they could choose the best one. The multiple shots from the bracketing are joined together in a digital darkroom into one final picture. To get full control over your exposure, work with all three exposure parameters: aperture, time, and ISO.

In every situation there is more than one combination of exposure settings that gives a correct exposure. If you change one setting to help achieve your creative goals, you have to change one or both of the other settings to maintain a correct exposure. When you are using its automatic mode, the camera is choosing all of them.
