This week, we will be discussing one of the most obvious factors that contribute to exposure, the shutter speed. Shutter speed tends to have a huge effect on your photos. When you don’t know how to use shutter speed correctly, you tend to have photos that are blurred. Continue reading below for a better idea on how to use shutter speed for your photos, whether you want sharp photos or prefer something more artistic.
First, we will discuss what shutter speed is. To summarize, shutter speed is the precise amount of time your camera will use to record an image. The camera’s shutter is how this is done. When the shutter opens, it allows light to hit the digital sensor or film plane.
Generally speaking, you will have camera shake if the shutter speed value is shorter than the focal length of your lens. For example, you will want at least 1/60 of a second for a 50 mm lens. You will need a tripod if you attempt anything slower. Another option is to have image stabilization on your camera.
Most times, it is best to snap your photo quickly, around 1/1000 of a second preferably. At this speed, the movement of the object will be frozen. Of course, you must take into consideration the speed your subject is moving and how far you are from your subject. For the most part, though, you will have blurred images if you use a slow shutter speed.
Just like aperture, stops are used in photography in relation to shutter speed. It seems to be an easier concept to learn, though. For example, understanding the concept of using half of an exposure in relation to shutter speed is simpler than understanding that same concept with aperture. You simply must remember that a full step down doubles the amount of light and a full step up will half it.
Once you understand the basics of shutter speed, you will be able to enjoy sharp images through your photography.
