  There are two elements to creating a “correct exposure”. These are aperture, and shutter speed, which we will look at first. When you press the trigger button on your camera to take a picture, it opens a set of sliders, like opening a window. How long it stays open, depends on how you set the shutter speed. Shutter speeds can range from extremely fast (ie 1/8000 of a second), to very slow (30 seconds), or even infinity if your camera has a bulb setting. These are extreme shutter speeds and not often used, except by people who shoot fast moving subjects, or in very low light. For most of us, we tend to stick to somewhere in the middle. As a general rule, the faster the shutter speed, the sharper your photo will be. For most people, anything at 1/60 of a second or above is acceptable when hand holding a camera. Lower if you have a particularly steady hand. If you need to use slower shutter speeds, you will need to use a tripod or rest your camera on a steady surface. These slow speeds can be particularly useful for creating blurred effects. For example the flowing water in a waterfall.
