1.The higher the ISO, you will capture more light so at low level conditions, like a baseball game or a night shot, you will see more of it.
2.Always try to stick to a low ISO, because then you won't rely on it for making light.
3.Only increase when the camera cannot get enough light, or you need ultra fast shots.
