Do you know what effect the different shutter speeds of the camera have on the photos?

Today, I will introduce the effect of using different shutter speeds on the picture.

As for the shutter, it was explained yesterday. What does the shutter control? The shutter controls the exposure time, so let's take a look at the picture first.

This photo is a small windmill that children like to play with. It looks static and looks like a small windmill.

But the small windmill in this photo looks virtual and full of movement. It is also a small windmill, why there are different picture effects.

At this time, we still have to return to the device structure of our shutter. Where is the shutter? The shutter is in our camera. It is like a curtain.

Is to control the length of light entering the camera. For exposure, shutter affects the length of exposure time. For picture effects,

I believe many friends will take similar photos. You see the picture on the left is very clear, but the picture on the right is very vague, or the pictures that we beginners often take are very vague. So today, let's look at what caused it.

Let's review the shutter speed mentioned last time. Shutter speed is calculated in seconds. The larger the denominator, the faster the shutter speed at this time. On the contrary, if the denominator is smaller, it means that our shutter speed is slower. Everyone knows this now, but how fast is this shutter actually used? How slow? According to these figures, you may not have obvious cognition. Then, I took a group of videos to give you an intuitive understanding of the shutter speed. Let's first look at the shutter speed of 1/2 seconds.

This is our real shutter curtain structure in the middle, and I will press the shutter behind. Let's feel it. What is the shutter time of half a second? You can see the obvious shutter opening process, and then let's look at a relatively fast1125 seconds.

Look carefully, don't open your eyes, because if you open them, you may not see them. You will find that the quick curtain in the middle seems to be flashing. Next, let's look at a faster one,11000 seconds.

Let's feel,11000 seconds, can our eyes still feel the change of the shutter? I wonder if you can see it clearly.

I believe everyone should be similar to me. At11000 seconds, human eyes can't capture the movement change of shutter curtain. When we just watched1125 seconds, we could still see the shutter curtain flashing after opening, but it reached 1/65438. And now many of our cameras can reach 1/8000 seconds. What difference will different shutter speeds bring to our shooting? Then let's look at another picture.

This is a small toy with clockwork, which can rotate. After the repair, we shot at different shutter speeds. At this time, we will find that the villain's arm is clearer at1100 seconds. If it reaches 1/4 seconds, the villain's arm can't be seen clearly, so shooting moving objects with different shutter speeds will get different effects. Moreover, the camera can also take a lot of scenery that we can't see with the naked eye.

For example, we often watch these slow videos on mobile phones, and we can even see the trajectory of bullets, which is usually invisible to the naked eye.

For example, sports photographers now take pictures of athletes flying in the stadium.

Including the facial expressions of the characters, which is the charm of photographers,

It's also football, so we can still shoot things like this at this time, and we can also shoot things like this.

Shooting these dynamic pictures will lead to different picture effects because the photographer uses different shutter speeds.

What is the result? If you are shooting a moving object, the faster your shutter speed, the closer the object is to stillness. On the contrary, if the shutter speed we use is slow, it will be easy to take the feeling of virtual shadow, just like the picture we saw just now. Why are some clear and some vague? Because the clear ones are often shot with a fast shutter, and the blurred ones are often shot with a slow shutter.

For example, many friends like to take pictures of scenery, and many photographers like to take this water into a fog, that is, with a slow shutter and a long exposure. Then, we will introduce this photography technology to you.

Next, let's look at a photo. You find that the characters in the center of the stage are blurred, but the stage is clearly visible. To understand this, we must first know a physical knowledge that we learned in junior high school: it is relatively static, just like A and B are moving in parallel, and A and B are both static when they look at each other. After understanding this truth, let's take a look at this photo. There are no figures in the picture, and the stage is clear, so the stage and lens are relatively static. So taking this photo is very simple. Just fix the camera and slow down the shutter speed. As long as your shutter speed is slower than the speed of human movement, you can shoot this dynamic effect.

Let's take a look at this photo again. In this photo, the earth is clear and the characters are dynamic. That's the same as the number on the stage just now. When shooting, we just need to fix the camera with a tripod and then slow down the shutter speed to get this dynamic effect.

But let's look at this picture. In this photo, people are moving, but people are clear. How should I take it?

We still need to understand the concept of relative stillness that we just talked about. If the moving person is clear and the camera and the person are relatively static, then the camera must move. Therefore, when taking this photo, our camera lens should aim at the movement and relative movement of the characters, so that the characters are relatively still, so that the characters can be taken clearly and the surrounding environment is empty. This is the legendary focus shooting.

Some students will definitely ask: Teacher, how much should the shutter speed be adjusted to take such a photo? In fact, there is relative experience in shooting such a picture, which can be set according to the reciprocal of the motion speed of your subject. For example, this person's riding speed can reach 50 km/h, and if you want to catch up with this athlete, your shutter speed needs to be greater than 1/50 seconds. For example, if you want to film a person running, the running speed of a person is about 15 km.

When shooting this effect, you should also pay attention to the problem that the subject must be horizontal in front of you.

Because your lens can only turn left and right if it is sideways. If you shoot a person and run in front of you, if your camera turns left and right, you and Ben can't shoot a person, right?
