What kind of shutter speed will not make people's movements empty?

Using a safety shutter when taking pictures can ensure the picture is clear.

Safety shutter means that if the camera shutter is lower than this value during exposure, the photo will be blurred due to the vibration of the body (breathing, shaking of the hand-held camera).

The safety shutter speed is not a fixed value, and it will change with different shooting equipment, shooting conditions and shooting objects.

Generally speaking, the safe shutter speed is related to whether a tripod is used, the focal length of the lens, the moving speed of the subject and the distance and angle from the camera. These shooting factors determine what kind of speed should be used as the safe shutter speed to ensure the clear photos.

The calculation method is:

APS-C format camera: the reciprocal of lens focal length * 1.5 (Canon is 1.6). For example, if you have a Nikon camera with a fixed-focus lens with a focal length of 50mm, the safety shutter will be 50* 1.5, which is1/75s.

Full-frame camera: reciprocal of lens focal length. For example, if you have a Nikon full-frame camera with a fixed-focus lens with a focal length of 50mm, the safety shutter is 1/50s.

On the premise of ensuring this value, if you want to solidify people's movements instantly, you must use a faster shutter speed to ensure that you can capture them.

Extended data

Shutter speed is mainly combined with aperture value and ISO sensitivity to obtain correct exposure. It doesn't matter how fast the shutter speed is set for a still object. As long as your hands don't shake, you won't spend it.

For moving objects, increasing the shutter speed can get the static moment of high-speed objects, while low-speed shutter will make the objects blurred and dynamic. For example, there are waterfalls. High speed can make the water flow still to get the details of the waterfall, while low speed makes the water flow look like a gauze.

High speed shutter and low speed shutter:

In addition to controlling the exposure, we can also "freeze" the instantaneous picture or create a dynamic blur effect by adjusting the shutter speed.

The picture taken by the high-speed shutter is still and clear, which can "freeze" fleeting moments. If the shutter speed is low enough, we can even shoot bullets parked in the air.

Low-speed shutter is suitable for shooting the trajectory of objects, and the effect is very unique.

Using low-speed shutter photography technology, such as moving car light trajectory, atomized running water, light painting of various patterns in the air, etc., is called long exposure photography or slow door photography.
