What Is Shuttering?

Shutter speed is an important parameter for digital camera shutters. The shutter speeds of different types of digital cameras are completely different. Therefore, when using a certain type of digital camera to shoot a scene, you must first understand its shutter speed because Only when the shutter startup time is taken into account when the shutter is pressed, and the release timing of the shutter is grasped, a vivid picture can be captured.

Normal digital cameras

As for SLR cameras,

Shutter speed is expressed in seconds or fractions of a second. Different camera manufacturers start with different shutter speeds

Range, this range is also important. All SLR cameras have at least the following shutter speeds (maybe more): 1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, and 1/1000 seconds. The speed of some cameras is simplified, such as marking 1/30 of a second as "30". In order to distinguish between the second and the fraction of a second, different colors or special

The marks indicate these numbers. For example, Nikon and Canon's bodies indicate seconds by adding a semicolon (") after the number 2, so 2" means 2 seconds instead of 1/2. Read the manual of your camera carefully to see how your camera is distinguished.

Looking at the series of shutter speeds above, you will find that each shutter speed is half of the previous speed, but twice of the latter. For example, 1/125 seconds is half of 1/60 seconds, but twice of 1/250 seconds. They all differ by one "stop", and each stop is half or double the time. From 1/125 seconds to 1/250 seconds, it moves one gear (halving the time), to 1/500 seconds, it moves another gear (halving again), and by 1/1000 seconds, it moves three gears. Here's a little test: How many stops do you need to move from 1/30 to 1/500 of a second? In the opposite direction (toward the slow shutter speed), how many stops need to be moved from 1/30 second to 1/2 second? Do you know the correct answer? The answer is simple: they all need to move 4 blocks.

When the camera is set to a certain automatic exposure mode, most cameras can achieve "stepless" shutter speeds. That is, the shutter speed can be determined by the electronic device and set to any shutter speed without being limited by a fixed gear. But even if the camera is set to this mode, the concepts of "halving" and "double" still exist. Among the newly released cameras in recent years, the shutter speed of most cameras can be increased or decreased by 1/3 stop. For example, the shutter positions of a Nikon camera include: 1/8, 1/10, 1/13, 1/15, 1/20, 1/25, 1/30, 1/40, 1/50, and 1 / 60 seconds and so on. From 1/30 to 1/60 seconds is a first gear. Similarly, from 1/20 to 1/40 and from 1/13 to 1/25 is a first gear.

When you change the shutter speed, you also change how moving objects are recorded on the film. The faster the shutter speed, the clearer the moving object will appear on the film. On the contrary, the slower the shutter speed, the more blurred the moving object will be.
