How does photography produce the dynamic "dynamic effect" of photos?

How can I take a dynamic "dynamic effect" photo? Can the teacher bask in the sun? For the "dynamic effect", it mainly reflects the sense of speed and strength, so it is particularly important to choose different shooting methods. What are the common shooting methods of this kind of subject matter?

1, focus tracking

Using the characteristics of relative motion, the camera and the object can keep synchronous horizontal motion at similar speed, and with appropriate shutter speed, works with blurred background and flowing feeling can be photographed.

▲ Focused shooting can highlight the dynamics of the subject and increase the impact; In addition, the blurred background can reduce the interference elements in the picture.

Please refer to the previous article for focus tracking. What is focus tracking? Focus shooting skills, how to take smooth photos?

2, high-speed condensation

Such as splash, bullet shooting, sports, birds flying and other sports moments, to freeze such sports moments, you need to use a high-speed shutter. According to different conditions, the instantaneous picture of high-speed movement can be condensed between 1/800 seconds and 1/8000 seconds.

For example, at the moment of splash, according to the speed of water flow, the effect of splash can be taken by using the shutter speed of about 1/800s in the river; For waterfalls, the shutter speed is11000s or faster; The shutter speed required by ocean waves is the highest, and it usually takes11500 s or faster to clearly capture the splash moment of ocean waves.

▲f/ 10.0， 1/2500s，ISO 100

It should be noted that if there is insufficient light in the scene, in order to get enough exposure at a higher shutter speed, the camera settings need to increase the aperture or improve the ISO. You usually need to shoot with a tripod or a monopod.

Step 3 slow the door

Long exposure (slow door), as the name implies, is to extend the shutter to get long exposure. The camera no longer captures short moments, but records the picture changes in a period of time. Common things such as slow running water, traffic tracks, fighting and shifting stars, light painting and so on.

▲f/ 10.0，20s，ISO 100

▲f/ 1 1.0，25s，ISO 100

▲f/9.0， 13s，ISO 100

Please refer to the pre-literature slow door shooting: slow door shooting techniques, parameters, creativity, novices can also play good works.

4. Enlarge the explosion

Simply put, exposure is push-pull zoom, which is shot at a slow shutter speed. When exposed, push-pull zoom produces an interesting background effect, making the work look like it is moving.

▲ Shoot the starry sky and use the exposure effect to make the starry sky look like an explosion, full of shock.

It is best to use a lens with a large zoom ratio, because a lens with blasting effect needs to use a lower shutter speed. If shooting in a dark environment, the photographer may use the B door to achieve a longer exposure time. Then in order to ensure that the picture will not appear obvious jitter, the photographer needs to use a relatively stable tripod to shoot, and ensure that the zoom operation during exposure will not make the camera shake.

▲ In the low light environment, using a tripod can ensure that the buildings in the distance are relatively clear, and at the same time, it can achieve a relatively obvious explosion effect.

It should be noted that there is no fixed shutter speed value that can meet the requirements of all situations. Factors such as light intensity and zoom speed will affect the choice of shutter speed. When zooming, keep a constant speed, neither fast nor slow, so as to get more continuous and linear radiation.

5, combined with flash shooting

Hou Lian synchronization: It means that when the curtain is opened, the flash will not flash first, but it will flash and complete the exposure just before the Hou Lian is closed. It is mainly used to shoot objects with relative movement tendency and activities, such as people, moving vehicles, animals, sports and dance themes. To show the dynamics of light and shadow and keep the theme clear at the last moment.

▲ Hou Lian synchronization can also be used to record dynamic pictures.

Strobe: Simply put, the general flash flashes once, and stroboscopic means shooting once and flashing many times. In other words, during your exposure, the flash will flash several times at a certain time interval. The significance of this is that clear moving objects can be frozen many times, and the trailing virtual shadow effect can be formed between clear objects. ▲ High-speed stroboscopic can capture the effects invisible to the naked eye, and the patchwork images also show the tension of moving objects and the rhythm of the picture.

Of course, the method of expressing the motion of the picture is not limited to this. It is very good to use diagonal composition to express motion, to synthesize motion trajectory with multiple exposures, to delay photography, and to realize motion blur in the later stage.

▲ Diagonal composition is dynamic.

▲ Use PicsArt's "fuzzy" tool to achieve the effect of slow door+shaking.
