How does the camera height adjust the video?

How to Adjust the Height of BMW x3 Camera

1, put in reverse gear, and then go to the place where the reverse image is installed at the rear of the vehicle. Generally, it will be installed in the license plate light position of the backup cover, and some will be installed under the rear bumper. We can adjust the field of vision by rotating this camera up and down.

2. The camera of the reversing image should be based on the center of the car width, so as to ensure a more comprehensive view of the rear;

3. During use, pay attention to the distance between the marking line on the screen inside the car and the rear object to prevent it from hitting the rear object. You can try it yourself.

The camera lens is below the horizon, shooting from bottom to top. It is very suitable for representing tall and vertical mouse objects, and makes full use of the depth of business surface to represent the height of sacrifice. Head-up shooting has changed people's visual habits, and also changed the visual perspective relationship of human eyes to observe things, giving people a sense of freshness, especially increasing the intensity of most objects and exaggerating the star effect. Looking up shooting can often form a contrast, deepen the theme and enrich the content of the business. Pictures taken from different angles convey different information, and the same thing will have different psychological feelings because of different perspectives. Look up to a goal. The viewer will feel that this goal seems to be particularly tall, whether it is people or scenery. If you want to make the shot image look higher, you can lower the shooting angle of the camera and shoot it obliquely. This kind of shooting can strengthen the dominant position and make the subject look more majestic and tall.

Camera shooting skills and angles

Camera shooting skills and angles

Camera shooting skills and angles, when shooting with a camera, there are certain methods, as well as the distinction between angles and skills, so that the shot is more beautiful. I have compiled information about camera shooting skills and angles for everyone. Let's have a look.

Camera shooting skills and angles 1

There are three shooting angles: Ping She (horizontal shooting), upward shooting (bottom-up shooting) and downward shooting (top-down shooting).

terrestrial fire

Most of the pictures should be taken horizontally by the camera, which is more in line with people's visual habits and the picture effect is relatively peaceful and stable.

If the height of the protagonist is equal to the height of the photographer, it is the most correct way to stand up straight and put the camcorder at the height between the chest and the head, and it is also the most comfortable position to hold the camcorder.

If shooting people or things above or below this height, then the photographer should adjust the camera height and body posture at any time according to the height of people or things. For example, when shooting the protagonist sitting on the sofa or a child playing on the floor, you should kneel down or even lie prone on the ground, so that the camera and the subject are always on the same level.

Shoot from bottom to top

Photographs taken from different angles convey different information. The same thing will have different psychological feelings because of different perspectives. Looking up at a target, the viewer will feel that the target seems to be particularly tall, whether it is people or scenery. If you want to make the image of the subject look higher, you can lower the shooting angle of the camera and shoot obliquely upwards. This kind of shooting can strengthen the dominant position and make the subject look more majestic and tall.

When shooting close-ups of characters, different shooting angles can bring great changes to the expressions of these characters. If you shoot from a low position, you can improve this person's mighty and tall image. Will make the leading role more prominent. If the camera is set low enough and the lens is facing up, it will make this person more intimidating, and even what the protagonist says will add weight. The audience will feel oppressive when they see such a picture, especially the close-up, which is particularly strong. The character bowed his head a little and even felt threatened.

When shooting from bottom to top, it should be noted that the effect of this angle is usually not ideal, because facial expressions will be exaggerated and obvious deformation will often occur, and using this angle in inappropriate occasions may distort and vilify the subject. Remember not to abuse this effect, occasionally use it to render the atmosphere and enhance the visual effect of the film; If you use too much, the effect will be counterproductive. But sometimes photographers will use this distortion and exaggeration to achieve extraordinary visual effects.

Shoot from top to bottom

The camera position is higher than the subject, and the lens is tilted downward to shoot. Ultra-high angles are usually used to display scenes in combination with ultra-far pictures. It can be used to shoot big scenes, such as street scenes and ball games. It is easy to show the layering and depth of the picture when shooting with panoramic view and medium lens.

If you look down from a higher place, you can completely show all the pictures from close range to long range, giving people a vast and broad feeling. Shooting with a high position and a large overlooking angle can increase the three-dimensional sense of the picture, and sometimes make the subject in the picture dramatic.

Contrary to the effect of upward photography, shooting close-ups from a high angle will weaken the momentum of the characters and make the audience feel condescending about the characters in the picture. The characters in the picture will look shorter and fatter than they really are.

If you take a close-up from a position above the photographer's line of sight, it will sometimes taste a little contemptuous, which should be noted; If you shoot from above and leave a lot of space around the characters, the characters will appear lonely.

Shoot from the perspective of people

The reflection of perspective should conform to the habit of normal people to see things. Sometimes, it may be necessary to show the perspective of the subject. In this case, no matter whether the shooting height is high or low, you should shoot from the eye height of the subject. For example, when a standing adult looks at a child, he should aim the camera at the height of his head and shoot down at the child. This is what the adult sees. Similarly, when children look up at adults, they have to lower the height of the camera to look up.

For another example, the scene of a person squatting on the ground to show the person in front of him is: first, he should lower his height (the same as the position of the squatting person's eyes) to shoot the person's feet, then slowly move the camera up to take pictures, and finally reach his face instead of going directly to Ping She, which is in line with common sense.

A picture that looks directly down is usually used to show someone's downward perspective. Shooting at a high angle from a height with telephoto or wide angle can increase the distance between the viewer and the scene below.

Camera shooting skills and angles II

▲ How to find the best shooting angle?

By changing the angle of the lens or the position of the actor, you can greatly influence the emotional reaction of the audience.

Whose perspective does the story come from?

As a filmmaker, the most important question you should pay attention to is:

Whose perspective does the story or scene come from?

Who do we agree with in this scene?

Who should have the most shots and why?

When two people talk in a dialogue scene, show more reaction shots of one of them. If you want them to be equal, the two characters should have the same number of shots.

How many people should be in the camera?

In the dialogue scene, do you just want to show a person who is talking, or do you include the person who is talking to him? The appearance of the second person in the camera will make a huge difference.

At this time, the use of the over-the-shoulder pat is the most powerful, even if it is only the shoulder pat, it will be different, so the dialogue becomes antagonistic.

How old should the characters in the lens be?

I don't think there is a better answer than Hitchcock's suggestion-the most important thing should be the biggest one in the camera.

This is why close-ups are so powerful.

However, if you want the actor's body language to be clearly visible, then obviously you need a middle shot.

Low angle/high angle

The vertical angle of the lens will make people look more important or less important, which has been proved countless times in movies.

Low angles are used to make people look more threatening or taller:

High angles make characters look weaker or smaller:

Follow the focus

Following the eyes or focus is a powerful skill to keep the audience watching your movie.

Suppose in a shot, the focus is here:

In the next shot, if it can keep the same focus, the audience doesn't have to move their eyes:

This is a continuous process.

However, you can also break this rule and force the audience to jump around on the screen, creating tension and confusion.

The feeling of the picture

This most important technology comes from director Emile Costa Rica. As a filmmaker, every time you look at a photo through the viewfinder, your heart beats faster. You should be excited and feel something.

If you don't feel this way, maybe you missed something. You should stop and see what's going on.

Each shot should provide new information or advance the story.

When you compare bad movies with good movies, you will find that this is the most important difference.

Each shot should provide some new information or advance the story. If you do this, the audience will keep staring at the film.

Camera shooting skills and angles 3

0 1, shooting horizontally.

Our first shooting angle is horizontal shooting. Horizontal perspective of eyes can produce neutral perspective. This is just like people we see in real life-our eyes are connected with theirs, which can break the barriers and boundaries between people.

Game of Thrones

02, low angle shooting

Low-angle photography shoots subjects from under their eyes. These shots usually emphasize the status gap between characters-the low-angle shooting of one character is often combined with the high-angle shooting of another character.

The Matrix

03, high-angle shooting

When shooting from a high angle, the camera points down at the subject. This usually produces a sense of inferiority or looks down on your subject.

The Avengers.

High-angle shooting is a kind of multifunctional shooting, which can be used in many occasions. The most common usage is to make the character look weak, but there are always exceptions.

04. Seven shots

A shot with seven heads means that your camera angle is about waist-high. When one subject is sitting and the other is standing, it is usually useful to shoot horizontally with seven heads. When there is movement near your hips, such as a weapon being pulled out or someone putting his hand into his pocket. That's why it is also called "cowboy".

Personalized love disorder

05, knee level shooting

This is when your camera is as low as your subject's knee. If matched with a low angle, they can emphasize the advantages of the role. Not as extreme as shooting on the ground, but it gives people the same feeling. These are ideal when you want to concentrate on people walking, or in this case, climbing mountains from home.

At home alone.

06, ground shooting

Ground shooting means that the height of the camera is consistent with the ground height of the subject. The angle of this lens is often used to show that a character walks without showing his face. It can attract the audience's attention more, and let the audience imagine the next story in their minds by using the actor's performance.

Burn after reading.

07, shoulder-level shooting

Shoulder level shooting is as high as the subject's shoulder. Because the camera is aligned with the shoulder, it allows the actor's head to reach the top of the picture (reducing the head space). It also makes the actor's line of sight slightly higher than the camera, thus giving people the illusion that the angle is slightly lower.

Black Panther

08, Dutch angle or oblique shooting.

Dutch tilt means that the camera leans to one side. In this way, you can create a sense of loss, an unstable mental state or use it to increase tension.

Task: Impossible.

You can use the Dutch horn to express any tense or subjective moment. This is a very good way to enlarge all kinds of emotions, psychological states or suspense in movies.

09, prone pat

Looking down is looking down at your subject from above. These are usually taken from above 90 degrees, and anything below 90 degrees can be considered as high-angle shooting. The height of overhead shooting is either high or low.

The Great Gatsby

The overhead lens is very effective for providing perspective of the scene. In addition, it is usually used to describe "neutral" or "sacred" scenes.

10, aerial photography

Both aerial photos taken by helicopters and drones are taken from high altitude. It allows you to see the whole scenery in the lens. In Black Hawk Down, many helicopter shots were taken by aerial photography.

Black Hawk Down.

The popularity of drones makes it easier for filmmakers to use aerial photography. Initially, aerial photography was once considered as a high-budget luxury, and now almost all productions can be used, thanks to the "rise" of drones.

How to shoot a camera in SKETCHUP, and how to adjust the sight distance and height?

1. Point to locate the lens (there is an icon of a villain), and then click the left key in the position you need in the model to confirm the position. Then use the keypad to enter the height, such as 1600 or 1700, which is almost the sight height of China people.

2. You will see that the cursor becomes a pair of eyes. At this time, press and hold the left key to move up and down, left and right, and adjust the direction of sight.

3. Press the zoom key with the left key, and then you can input the lens parameters with the keypad. The input method is xxmm, such as 28mm, and the viewing angle is adjusted (refer to the actual camera lens parameters).

Click the front observation icon (eye icon) to return to the function of adjusting sight.

4. If you feel that the distance between people and things is not suitable, click the roaming icon (a pair of black shoe prints), and press and hold the left key to move back and forth to adjust the distance, or press and hold Shift++wheel (press the wheel) to translate left and right, and then enter the height value again after adjustment to prevent changes.

Through the above, after repeated adjustments, the distance and line of sight can be basically determined. Note: Enter the height value after each adjustment to prevent the line-of-sight height from changing.

5. View-Animation-Add Scene. A small window will pop up, so it doesn't make much difference. You can use the window scene to modify it later.

Extended data:

When the two ends are connected, connect the camera with the computer host or camera hard disk to complete the installation of extended data;

Position requirements: For the surveillance camera, the position is directly related to the imaging effect of the equipment.

2. Therefore, many users regard the monitoring effect as the primary reference for monitoring the installation position of the camera.

3.2. Installation angle: There are mainly two types: cylindrical and hemispherical.

4. Cylindrical type is more common, both indoors and outdoors; Hemisphere is generally used indoors, which is small in size and can be installed on the wall or ceiling.

5. Direct light source should be avoided, and it is best not to install it against the light. Outdoor special supports should be selected as far as possible, but the wind resistance coefficient is quite different.

6.3. Installation height: The installation height of the monitoring camera should not be too low or too high, which will bring inconvenience to future maintenance. The recommended installation height is three or four meters.

I believe this article by Aniwell can help you. When you share it with your good friends, you are also welcome to discuss it with interested friends.
