Techniques for shooting moving images frozen .

Xieasdf is wrong, the correct one is that a shutter at aperture 1 500 is equivalent to a shutter at f4 aperture 1 1000 is equivalent to a shutter at aperture 1 2000.

If you need to freeze when shooting a moving subject, you generally use the shutter to prioritize the TV gear, preset the shutter speed, and then let the on-camera light meter automatically select the appropriate aperture value. Of course, the aperture is larger, the depth of field is smaller, and the background blur is obvious. If the maximum aperture flickering, it means that the maximum aperture is still not up to the normal amount under the current light and shutter speed, then the ISO needs to be increased.

Therefore, if you don't want a depth of field that is too small, for example, if you want to use a large depth of field to compensate for the difficulty of quickly aligning the focus point like F1, you also need to increase the ISO. So Nikon's D3 does a great job, and it's perfect for sports themes, with a maximum ISO of 25600.

In addition, if you only need to solidify and highlight the subject, you can also shoot in a way that follows the subject's movement, with the camera tracking the subject's trajectory and pressing the shutter. In this way, the moving subject is relatively stationary, so there is no need for too fast shutter, and there will be a drag in the background, reflecting the effect of the main movement. Otherwise, if the subject and background are frozen at a high speed, the movement of the subject will not be reflected.

High-speed shutter. For example, a shutter of 1 1000 - 1 8000.

Moving objects tend to be stationary.

The higher the shutter speed, the lower the light throughput, but you can increase it accordingly.

For example: A shutter speed of f-aperture 1 500 is equivalent to a shutter speed of f-aperture 1 1000.

Secondly, there is also the concept of ISO, you can set the ISO value in the camera, ISO is the ** speed represented, 1 500 ISO 100 and 1 1000 ISO 200 brightness is the same.

So when you need a high-speed shutter speed but the light intensity is not enough, open the aperture to the maximum and then the ISO as high as possible.

The suggestion is to give preference to the aperture as high ISO will affect the imaging) If there are still problems you can email me.

High-speed shutter, aiming at the subject and focusing well. With a wide aperture, of course, it won't be dark.

The premise of a high-speed shutter is, of course, to be able to achieve the desired amount of exposure. On sunny days, it is not a big problem to open the aperture wide, and on cloudy days, you have to use a slightly higher ISO.

It is to shoot a moving object in a stationary form,,, control it with a shutter, the shutter is fast enough to shoot the moment when the athlete is strong, this kind of scene, if the shutter is not fast enough, you will not be able to see a clear image, and the picture will be empty. This feature can be used to photograph the streets at night to create the effect of traffic flow. However, this phenomenon is usually not required.

And we often say that camera stabilization is to solve the problem of blurring the subject because the shutter is not fast enough to freeze the action.

If you want to shoot the ** of the freezing action, you generally need to use a lens with a large aperture, because in order to ensure that the shutter is fast enough (generally 1 160 1 2000) without causing ** deficiency, and in order to highlight the central subject and blur the background, the lens aperture is as large as possible. If you don't have a high-speed lens with good performance (that is, a large-aperture lens), or you can't guarantee it when you open it to the maximum, there is another way to increase the sensitivity, although it will sacrifice some of the image quality, but it is very effective. In addition, the use of flash to fill in the light is also a common practice.

ps: Maldini + Cannavaro sandwiching and shoveling Da Luo's ** is a very typical solidified action work.

To understand it, the target object is moving and the environment is frozen.

Solidification movement is to take a clear picture of the moving object to freeze the moment to express a sense of beauty in motion. For example, the moment when Liu Xiang crossed the hurdle, the moment when the motorcycle turned, etc. The characteristics of this kind of ** are that the people or vehicles and instruments as the subject are clear and sharp, and the scenery in the background is blurred.

When shooting such sports subjects, it is necessary to use a high shutter speed to shoot to get a clear and sharp image due to the fast movement speed of people or equipment in sports, and it is necessary to be proficient in the shooting technique of following photography.
