The moment that you press the button to take a photograph, you open a camera shutter. Camera shutter is the gate that lets the light in to expose the film or a sensor. Shutter speed ranges from the fastest 1/4000 second to the slowest 30 seconds. Among all, 1/2 to 1/1000 are more commonly used. Fast shutter speed means that the shutter is only open for a short period of time; a slow shutter speed means the shutter is open for longer.
The longer the shutter is open, the longer the film or sensor is being exposed to light. This means that the slower the shutter speed is, the brighter the image you can capture. However, any slight shaking of the camera or the movement of subject will result in motion blur.
To avoid motion blur while using slow shutter speed you would have to use a tripod and make sure the object of your shoot is not moving. If you’re photographing without the tripod, or if you’re photographing fast moving objects, you would need to use a fast shutter speed in order to get a sharp image.
Play around with shutter speed in the widget below to see how it affects the image.
As a rule of thumb, you should use a minimum shutter speed of 1/focal length. For example, for a 100 millimeter lens, use a shutter speed of at least 1/100th.Next: Aperture go back
