What are the shooting functions and modeling characteristics of the dithering lens?

There are various forms of translation, and different translation forms contain different picture vocabulary, each with its own expression meaning. Let's take a look at the shooting function of the panning lens with me!

Shooting modeling characteristics of shaking lens

Panning is like turning your head and looking around, so you can break through the limitation of TV picture frame, and use the motion of the camera to expand the surrounding pictures, broaden your horizons and contain more visual information. Translation focuses on introducing the terrain, stories or events of the environment and showing a broader visual background. It has the functions of a large scene and a wider field of vision than fixed the picture's. It has its unique expressive power in representing vast and far-reaching scenes such as mountains, grasslands, deserts and oceans. This method of expressing space and expanding vision by shaking the lens is usually done by shaking the lens evenly and smoothly at the speed of the distant or panoramic scene. Its purpose is to give a complete impression through the whole process of shaking, not to describe an object in detail. It pursues the overall image of the picture, not the description of the specific image.

Because it expands the performance space of the picture, horizontal panning can be used for wider objects, such as bridges and dams across the river, and vertical panning can be used for taller objects, such as skyscrapers and TV towers, so that the whole picture can be displayed completely and continuously. It is the development of translation movement, which shows the whole picture and form of the subject and forms a magnificent momentum. For some themes, such as long logo, flagpole, etc. According to the characteristics of the object, we can use a smaller scene, let the object fill the picture and exclude the meaningless parts in the picture, so as to achieve the purpose of distinguishing the big effect with the small scene.

Disks can introduce and explain the internal relationship between two subjects in the same scene, and can also connect two subjects with opposite or similar nature and meaning through disks to express some metaphor, contrast, juxtaposition and causality. If the connection between three or more subjects is shown, the lens will roll over or slow down or pause, forming intermittent jitter and connecting several subjects. In the movie "Crossing the Ocean", when Yahai and Yazhan just escaped from others and fled to the seaside, the camera shook them into the sea and saw two killers coming from the sea to shoot with airships, which made the audience feel nervous about the protagonist and the situation as soon as they were relieved.

Another example is shaking from the slogan "No Smoking" to the person who is smoking; From a flower to a group of naive children, the contrast factors in life are connected by two independent images, which makes its significance far beyond these two independent images, and has less traces of artificial processing than montage, which ensures the integrity of time and space and makes the information conveyed by the pictures more real, so it has unquestionable power in documentary programs. In addition, panning can not only establish some connection between two objects by shaking the lens, but also further explain the front object by shaking the back object, thus standardizing the audience's thinking. For example, the picture shows a person walking into a gate, shaking the camera and the post office sign appears. The picture clearly tells the audience through visual images that the person walked into the post office, not anywhere else. Because of the back picture, the meaning of the front picture is clearer. This seemingly unintentional but intentional expression is often used in film and television dramas, laying the groundwork for the subsequent plot development.

It is also convenient to display the dynamics, dynamic situation, direction and trajectory of the subject. For example, in TV sports programs, athletes can often be seen running, and the camera shakes with the running direction; When playing volleyball, basketball or football, the lens usually shakes with the direction of the ball. Especially when panning with telephoto lens, it is easy to separate the subject from scenes with different directions and different moving speeds, thus achieving the effect of highlighting the subject. In addition, a group of the same or similar picture subjects can appear one by one through translation, which can strengthen people's impression of this thing and form the cumulative effect of quantity and emotion. For example, in a feature film about family planning, there is a scene moving in the street. From the beginning of the lens to the left, people who are constantly moving and repeating appear on the screen. This panning lens prolongs the audience's visual experience of the crowd and deepens the impression of "crowding". Tell people vividly that no matter "energy crisis" or "water crisis", there is "human crisis" behind it.

In the shot combination, the current shot shows a person looking in all directions, and the space displayed by the next shot with shaking is the space seen by this person in the previous shot. At this time, the panning shows the line of sight of the people in the play and becomes a subjective lens. In addition, when the picture shakes away from the protagonist and shakes into the space where the protagonist stares, this kind of shaking lens also shows a certain line of sight of the people in the play and also plays the role of subjective lens. At the same time, translation can also guide the audience's line of sight from one place to another through the transformation of space and subject, and complete the transfer of the audience's attention and interest points. For example, an engineer is shaking scaffolding to the ground and analyzing drawings, which is the transformation from one scene to another.

When shooting with a panning lens, we should pay attention to the accuracy of framing and composition of the left picture, the accuracy of focus and the uniformity of panning speed, which are consistent with the emotional atmosphere and rhythm in the picture.

Analysis of macro lens shooting technology

Low power photographic lens

When you realize the charm of macro lens, every corner of the world will become different in front of you.

The microscopic world in the macro lens perfectly explains what is called "a heaven in a sand"

Macro lens can turn the familiar macro world into an unprecedented micro world.

Almost all photographers are new to the macro lens, and like the feeling of filling the whole picture with small things that are usually invisible, but in fact, the usage and function of the macro lens are far more than that.

Macro lenses are mostly fixed-focus lenses, the focal length is mostly between 200mm, and the aperture is relatively large, so they are outstanding in blurring the background and the imaging quality is also excellent, especially at close range.

In general, the macro lens can be used as a fixed-focus lens with excellent image quality.

The maximum aperture of most macro lenses is f/2.8, and the depth of field is very small when the aperture is fully open. We can completely apply the methods and composition techniques used in ordinary lenses to macro lens shooting.

As we all know, the depth of field depends not only on the focal length and aperture of the lens, but also on the focusing distance.

The focal length is extremely short, and the depth of field is often only a few millimeters.

In this case, in order to ensure the clear focus of the picture, it is best to set the focus mode of the camera to manual.

When shooting still life, it is best to install the camera on a tripod to further improve the focusing accuracy.

If you feel that the manual focusing accuracy of the viewfinder is limited, you can also use the camera's real-time viewfinder function to enlarge the picture.

For cameras that don't support live view function in the early days, you can also choose an enlarged viewfinder that matches the viewfinder, or a right-angle viewfinder with enlarged function.

focal distance

We used a 50mm macro lens when shooting. You can also choose the lens that suits you best in the focal length range from 35mm to 200mm according to your actual needs.

Like ordinary lens, when the scene accounts for the same proportion of the picture, the different focal lengths of the lens will also affect the perspective effect of the picture.

However, considering the shooting distance, this effect on the macro lens is not as obvious as expected.

The more important difference between macro lenses with different focal lengths is that the focal lengths are different at the same magnification. When shooting insects and other small animals that are easily frightened, a macro lens with a longer focal length is unlikely to interfere with them.

Focusing is very important when shooting macro, especially when the aperture is fully open.

Even the smallest focus error may cause the parts you need to be clear to become blurred.

Technical connection

Macroscopically compact

Maybe you will see macro or English logo“MACRO "in many lens parameters, but that doesn't mean they are real macro lenses.

The macro marked on the zoom lens can only show that their focal length is slightly closer than that of the ordinary lens, which does not mean that they can shoot small things very big.

Pay attention to the shadow

Use a short-focus macro lens for macro shooting, and the distance between the front lens of the lens and the subject is only a few centimeters.

The shadow of the lens or photographer is likely to be left on the subject without paying attention, so you must pay attention to this when shooting.

If this happens, you should adjust your position and shooting angle in time.

If you really can't avoid the shadow, you can stay away or take off the hood.

10 wide-angle lens shooting skills

1. Find the crux.

Wide-angle lens limits the photographer's vision, because there are too many scenes in the picture, and the photographer has to find out the tears to make the photo stand out. Puncture is a concept put forward by roland barthes, a literary critic. To put it simply, it is to provide a small detail and a small idea in the image, which inadvertently stung the viewer's senses, and this is the key to making people fall in love with a work.

2. Look at the image from a macro perspective

Because there are too many people and things in the picture, don't just pay attention to the details when shooting, you can look at the whole picture from a macro perspective. Duong mentioned Pragnanz's law. When composing a composition, he imagined simplifying things in the picture into simple shapes and lines, thus combining these shapes into an interesting and unique composition.

Guide the line of sight

It's difficult to get a shot with a wide-angle lens. There are too many scenes in the lens. To highlight the subject, it is necessary to guide the viewer's line of sight through the lines and composition of the picture, so that the viewer can pay more attention to the subject that the photographer wants to express.

Come closer.

This is especially suitable for taking portraits. If you want to capture the expression of the portrait and capture his present expression, you need to get closer. This also allows players who are used to using long lenses to get out of the comfort zone and try to have more communication with the subject.

5. Take photos with thinking about the scenery.

When taking photos of mountain scenery, seascape and other scenery, due to the long shooting time and wide field of vision, the location and line arrangement of the scenery will be very particular. You should also use this mentality when shooting with a wide-angle lens. Even if you shoot streets, you should pay attention to the lines of streets and the direction of pedestrians and vehicles, and wait patiently for the best moment of composition before pressing the shutter.

6. Dare to shoot exaggerated wide-angle effects

When using a wide-angle lens, the distance between the foreground and the background will be exaggerated, resulting in perspective distortion. If you make good use of the subject matter of the photo, you can shoot a unique effect.

7. Make full use of space

Wide-angle lens can shoot more scenery. If you don't want every photo to have a rich and complicated picture, you can try to leave a blank in the picture and make more changes.

8. There is a box in the box

Since the wide-angle picture is too wide, reset the photo frame yourself! Taking the shadow and the appearance of the building as the background of the subject can guide the viewer's line of sight and highlight the subject.

9. Try different shooting angles

If you want to make a good work that is different from others, you might as well make more new attempts. Shooting from less angles may bring surprises!

10. Make good use of light

The most difficult thing to use a wide-angle lens is to focus the viewer's eyes on the subject. Making good use of light to guide the viewer is also a good way to highlight the subject.

What are the lens angles for shooting?

Generally speaking, there are five lens angles:

1, bird's eye view: bird's eye view of the world.

2. High angle

3. Vision: People see the world.

4. Low angle: Generally speaking, dogs see the world.

Step 5 bevel angle

High angle lens

(bird's eye shot, corner shot): This kind of shot will show the plight, powerlessness and attack of the characters in the picture. bird

A bird's-eye lens and a overhead lens sometimes give people a sense of omniscience, just like "God's perspective" observing the fate of things. This kind of lens will also highlight the environment, making it look like it can devour the characters and make them look humble and helpless.

horizontal angle

Some directors don't want to use subjective lenses casually. For example, in the works of Japanese director Yasujirō Ozu, the camera is usually four feet above the ground-exactly the height of Japanese people sitting on tatami. Ozu regards his role as equal to his own, with no special virtue and no special degeneration. Ozu completely lets them show themselves and doesn't make value judgments from the perspective of the camera. So his lens is neutral, without emotion, and let the audience judge for themselves.

Elevation lens

Contrary to the depression angle, it will increase the height of the main body and have a vertical effect. The sense of speed has increased, especially in violent scenes. The elevation lens will increase the importance of the subject and make the object unfold in front of the audience, which is very threatening. Tasks taken from a height usually arouse a feeling of terror, seriousness and respect. Therefore, this lens angle is most common in promotional films and films that emphasize heroism.

dip angle

Most horizontal lines with inclined angles are inclined. The characters in the lens look as if they are going to fall down. This kind of lens is sometimes used for subjective lens, such as the drunk's perspective. In addition, in some special scenes, the tilt angle corresponds to the scene composition, which can expand the field of vision, which is another matter.

Shooting skills of moving lens

"Panning" photography skills can bring wonderful images to photographers, and it is also one of the important topics for photographers to master and control the shutter. The shooting principle of Pan mirror is very simple, that is, set several shutter speeds, and swing the camera with the moving subject during exposure to form an image with clear subject and blurred background, highlighting the dynamic motion of the subject.

1. Set the slow shutter

Select the shutter prerequisite mode and set the shutter to 1/30 seconds to try shooting. Don't shoot with a slow shutter. The photographer can adjust the shutter speed according to the scene light and the moving speed of the subject. Generally, they can try the shutter speed of 1/60 seconds when shooting vehicles in the street. A high-speed moving object can use a shutter speed of1100 seconds or faster. Photographers should remember this: the higher the shutter speed, the clearer the subject/background, but the less sports.

2. Continuous focusing function

Set the focus mode to continuous focus mode, and press the shutter half-way to start autofocus tracking the fuselage until the shutter is fully pressed for exposure. When the "translation mirror" is executed, the subject is actually moving. At this time, the continuous shooting focusing function is started, and the shutter is pressed for automatic focusing before shooting, so that the focus is locked on the subject. "

3. With the movement of the subject

Press the shutter gently and completely for exposure, and immediately swing the camera and the main body until the exposure is completed (using its own central axis rotation). This action can keep the subject in the image clear and the background blurred.

4. Choose the ideal shooting point

Find a safe place without obstacles to shoot images, and use a telephoto lens of about 85mm to keep the photographer at a certain distance to shoot images. In addition, photographers should also pay attention to the layout of the background, too messy or too bright background will weaken the appeal of the subject.

5. Flush with the main body

Keeping as horizontal as possible with the moving object can help the object stay in the focus range of the image, thus obtaining a clear image of the object.

6. Leave enough space for the main body

When composing a composition, there should be enough space in front of the subject, otherwise the subject will not have enough "room to move forward" and it will look cramped.

Use a monopod

If necessary, you can use a monopod to stabilize the camera to reduce the chance of blurring the subject.

Conclusion: Try more and practice more.

Before mastering the intermediate skills, the photographer may not get the ideal effect, but after many attempts, he can master the appropriate skills and find the fun, and then he can shoot special images that suit his personal style. In fact, photographers don't have to pursue a completely clear subject, because a slightly blurred subject can also set off the dynamics of the subject.
