I learned that the three camera settings: aperture, ISO, and shutter speed all determine the final look of a photo. The aperture controls how much light gets into the camera lens. It has different ranges of f-stops, the bigger the number, the smaller the hole. The ISO allows you to either darken up, or brighten up the image you are shooting. The larger your ISO number is, the brighter your image will be. The shutter speed is how fast your shutter will open and close, which allows light to come through. The shorter the second, the better quality your image will be.
