Exposure

                                                                          Exposure Triangle Summarized

      The exposure of any image is determined my the settings of the aperture,ISO, and the shutter speed.The aperture controls the area in which light enters, it helps decide how much light to let in.Shutter speed decides the duration for the exposure.ISO controls the sensitivity of the camera sensor to the light entering the lens.All 3 have though effect other things as well in the camera setting such as motion blur, depth of field, and image noise.Shutter speed decides how long the camera will stay open to let in light.If shutter speed is increased by 50% for example then the amount of light entering over the duration would also increase by 50%.Shutter speed can help capture something moving fast.Aperture decides not the duration of the light but how much light to let in. The smaller the f stop aperture number the more light is let in to the camera.Lower aperture f stops result in shallower depth of field.For ISO, a lower speed is preferred.In order to get the desired shot you want you need to know about the proper settings of all 3 on the exposure triangle.
