Most cameras offer a wide range of shutter speeds, starting at just a few thousandths of a second and going up to several seconds. SLRs also have a "Bulb" mode where you can hold the shutter open for as long as you want.
Shutter speeds are measured in seconds, or fractions of a second. For example, a shutter speed of 1/100 means 1/100th of a second, or 0.01 seconds. This is also known as the "exposure time", because it's the amount of time the sensor is exposed to light.
Inside your camera, directly in front of the sensor, is a small flap called the shutter. When you take a photo, this opens and closes to let light reach the sensor, creating your image. Shutter speed describes how quickly or slowly the shutter opens and closes again.
Shutter speed is how long an image is exposed to light — it can be milliseconds, or even minutes. As one of three elements that affect how light or dark an image is (called exposure), understanding shutter speed is essential to taking full creative control of the camera.
You can avoid camera shake by using a faster shutter speed. It's more noticeable when using lenses with a long focal length, so the longer the lens, the more you'll need to increase your shutter speed to avoid camera shake.
As a rule of thumb, you should use a minimum shutter speed of 1/focal length. So for a 200mm lens, use a shutter speed of at least 1/200th. When calculating this, use your lens's effective focal length, which is found by multiplying the focal length by your camera's
