By definition, the shutter speed is the time frame when you open the shutter on the camera. More easily, shutter speed means less time in which our sensor ‘sees’ a subject to our photos. Simply put the shutter speed is the time between us pushed the button on the camera until the shutter button is returned to its original position.
So easy, we translate this concept in some use in cameras:
- Setting the shutter speed of 500 in your camera means the time span of 1 / 500 sec. Yes, short as it is. As for the exposure time of 30 seconds, you’ll see something like this: 30”
- Setting the shutter speed on your camera is usually in multiples of 2, so we’ll see a row like this: 1 / 500, 1 / 250, 1 / 125, 1 / 60, 1 / 30 ff. Now almost all cameras also allow setting 1 / 3 stop, so less is more movement of the shutter speed is more dense; 1 / 500, 1 / 400, 1 / 320, 1 / 250, 1 / 200, 1 / 160 … and so on.
- To produce a sharp image, use a shutter speed that is safe. Rules safe in most conditions is setting the shutter speed of 1 / 60 or faster, so the resulting image will be sharp and safe from the photos that ghosting (blur / out of focus). We can outsmart the safe limit of this with a tripod or use the Image Stabilization feature (discussed in upcoming posts)
- Limit the other safe shutter speed is: shutter speed we should be larger than the length of our lens. So if we use a 50mm lens, use a minimum shutter 1 / 60 sec. If we use the 17mm lens, use a shutter speed of 1 / 30 sec.
- Shutter speed to freeze motion. Use a shutter speed as high as reasonably achievable to freeze motion. The faster the object moves that we want to freeze the image, the faster the shutter speed is needed. To freeze the motion of a flying bird for instance, use the Shutter Priority mode and set shutter speed at the rate 1 / 1000 sec (ideally ISO set to auto option) so that the results are sharp. If you notice, sports a much idealized fashion photographer S / Tv this.
- Blur deliberates – the shutter speed to show motion effects. When photographing a moving object, we can deliberately slow shutter speed to show the effects of our movement.
