I’ve learned that camera exposure is how much light is being let in. The amount of light that’s being let in will determined whether your photo becomes light or dark. I also learned about the f-stop. You use f-stop for a small or large aperture depending on the number. A higher number f-stop is a lower aperture, and a lower number f-stop is a larger aperture. Now the shutter speed is the length of time the camera shutter is open. So its how long your camera spends taking the picture. A fast shutter speed basically is what it takes to freezes action in a photo.
