How to shoot with a zoom camera

What are the shooting skills of home cameras?

With the development of economy, home cameras have become a necessary shooting product for some families. So what are the shooting skills of home cameras? Next, I'll take you to understand.

1. How to use the camera: Zooming is a basic function of the camera. The zoom function of a camera is much stronger than most cameras, but please remember that powerful functions are by no means abuse. Simply put, zooming in is to emphasize the scenery or people we want to shoot, and zooming out is to show the whole picture of the object or the scene of the story.

2. Tips for dynamic shooting: When shooting dynamically, try not to move your feet, set up the camera, turn the upper body into an animated circle with the waist as the center, sweep the scenes and scenery that need to be shot into the lens one by one, and then sweep them back when necessary, stop shooting after a short period of rest, and continue shooting after changing the lens angle.

2. Adjust the exposure and focal length: adjust the exposure to the manual position, and then reduce the exposure according to the light condition until the required intensity is obtained. It should also be emphasized that the color and brightness of the images we usually see on the camera LCD screen are different from the images finally collected in the computer, so we should pay attention to the differences between them when collecting and shooting, and often compare them, so that we can know what the images we see on the LCD screen are and clearly know what the images finally collected are.

Try not to go to places where the sun is particularly strong, and the effect is not good.

How to use zoom lens correctly?

Many novice photographers will ask me whether to buy a fixed-focus lens or a zoom lens when they start to learn photography. I always say that the fixed-focus lens is not as useful as you think. For example, Bresson, a master photographer, is famous for being good at using 50mm lenses, but most of us, including senior wizards, may not be good at using 50mm lenses. One of my teachers once told me that he was only good at 35mm, but he really couldn't learn Bresson's 50 mm, so the fixed-focus lens really didn't work that well. When we first learn photography, we don't consider the fixed-focus lens, but choose the zoom lens directly.

Wait, I don't think I'm finished. As I said just now, I suggest that beginners choose zoom lenses when they start to learn photography. I want to talk about this topic. Now I feel that 99% of people use the wrong zoom lens. Why do you say that? Take the 24- 105mm lens that I often use. The focal length range covers the focal lengths of five fixed-focus lenses of 24-70mm-35 mm-50 mm-75 mm-100 mm, as well as some common zoom lenses, such as 18-55mm, equivalent focal length of 24-85mm, 15-85mm, and the residual EF-S lens. Almost all of them cover four focal lengths of 24mm, 35mm, 50mm and 75mm, but if you really want to shoot a large film with such a lens. Do you feel this way when you take pictures? The landscape angle of 35mm shooting is still not wide enough, and the portrait is close to the facial deformation caused by the difference of sensory angle of view. The viewing angle of 50mm is obviously too small, and the focal length of the portrait is obviously too short. As a medium telephoto, the focal length of 75mm is really not long enough, the effect of compressing the background is not obvious, and the main body is not prominent enough. Therefore, I really suggest that you start learning photography by using a zoom lens. 24-70mm and 24- 105mm are good lenses for our practice.

However, I see that most novice photographers and even many old wizards basically stand in one position when using the zoom lens, that is, they take pictures by turning the zoom ring. I want to say that the usage of zoom lens is definitely not the commonly known usage of "pulling bellows". How to use the zoom lens? The correct way is to shoot a subject and think about using a focal length in advance. For example, if you want to use a focal length of 50mm, zoom the lens to this focal length of 50mm and then make a composition. In the process of composition, you don't rotate the zoom ring, but rely on moving your feet back and forth to make a composition. Having said that, you may understand that this is how to use the fixed-focus lens. Yes, that's right. At this time, if you find it difficult to make a composition by moving your feet, you can redefine a new focal length, such as 35mm, and then make a composition by moving your feet by 50mm as just now. In fact, in the final analysis, we just regard the zoom lens as several fixed-focus lenses. If you practice like this, after a period of time, you will find that your concept of focal length and perspective has improved to a higher level, and gradually you will find that you need to move your feet to make a composition when taking pictures. In fact, this is your progress, and you have a sense of lens commonly known in photography. Using the zoom lens like this for a long time and then using the fixed focus lens will naturally be easy to master and use.

How to use zoom lens

Lead: For digital SLR lenses, we usually don't mention the concept of "multiple zoom". How to use the zoom lens? Come and have a look with me!

How to use zoom lens

Like a fixed-focus lens, we look at it through the focal length. For zoom lenses only, there are two focal lengths. One is the focal length of the wide-angle end and the other is the focal length of the telephoto end. The focal length of the zoom lens can be continuously changed within these two values.

It is worth noting that for digital SLR lenses, we usually don't mention the concept of "multiple zoom". Give a very simple example, I believe everyone will understand. Zoom lenses with a focal length of 24 ~ 70 mm and zoom lenses with a focal length of 70 ~ 200 mm can both be called triple optical zoom (multiple zoom is calculated by dividing the focal length of the telephoto end by the focal length of the wide-angle end, and the number obtained is multiple zoom. 70/24 and 200/70 are both slightly equal to 3, so we can all regard them as 3x optical zoom. But obviously, the scope of application of the two is completely different. 24 ~ 70 mm lens is suitable for shooting landscapes and portraits, and 70 ~ 200 mm lens is more suitable for shooting works with ecological, sports, stage and other themes. Therefore, for the lens of digital SLR, it is of little significance to talk about multiple zoom. What we value more is its focal length.

However, on the other hand, it must be admitted that the greater the zoom factor of the lens, the wider the scope of application of this lens. For example, a lens of 18 ~ 200mm has a focal length ranging from wide angle to telephoto, which is suitable for almost any subject. With such a lens, you can "walk the world in one mirror" and it is very convenient to use. _ tell a low-paid lie, the color is steep. You can't telex me anything, but you can't punish Tuoxin Reef. The wide focal length of the gun can forgive R, and the other is the focal length of the telephoto end. The focal length of the zoom lens can be continuously changed within these two values.

What's the lens?

The lens has two fingers in film and television. One is the optical element used by film cameras and projectors to produce images, which consists of multiple lenses. Different lenses have different modeling characteristics, and their application in photographic modeling constitutes an optical expression means; The second finger refers to the picture taken continuously from power on to power off, or the fragment between two editing points, also called ytterbium head. One finger and two fingers are two completely different concepts. In order to distinguish, one refers to the optical lens and the other refers to the lens picture.

The lens referred to in film and television is not a physical or optical lens, but a lens that carries images and can form a picture.

The lens is the basic unit of the whole movie. Several shots make up a paragraph or scene, and several paragraphs or scenes make up a movie. Therefore, the lens is also the basic unit of visual language. It is the basis of narration and ideographic expression. In the early shooting of film and television works, the lens refers to the sum of an uninterrupted picture taken by the camera from the beginning to the stillness; In post-editing, a shot is a set of pictures between two editing points; In the finished film, a lens refers to a complete segment from the front optical transformation to the back optical transformation.

The main function of the lens is to collect the reflected light of the illuminated object and focus it on the CCD. The image projected on the CCD is inverted, and the camera circuit has the function of inversion. Its imaging principle is the same as that of human eyes.

Lens classification

According to the origin of lenses, mainly Japanese lenses and German lenses. Japanese lenses mainly have good color reproduction, while German lenses have a strong sense of layering. China's lens has gradually occupied a certain market in the market, mainly because the price is relatively low.

How to use zoom lens well

Lead: We must pay attention to what kind of zoom lens we choose and what problems we should pay attention to in our photography activities. Because zoom lens is the most frequently used lens in our photography activities, it also has its limitations due to the reasons of structure and manufacture. The following are my recommended techniques for using zoom lenses. I hope everyone will read it carefully!

Try to avoid using the maximum aperture.

In order to get higher shutter speed in photography, we have to open the aperture of the large lens when the light source and sensitivity cannot be changed. Because the maximum aperture of zoom lens is too small, it is often necessary to open the aperture L to the maximum. The lens has large aberration, small contrast and low resolution when the aperture is fully open. Although the maximum aperture of zoom lens is a common aperture value, it is necessary to reduce the aperture to get good imaging. For example, a fixed-focus lens with a maximum aperture of F2 and an aperture of F5.6 can obtain better imaging; For zooming with F4 maximum aperture, at least F8 aperture can be used to obtain good imaging. The optimal aperture of most zoom lenses is around F 16. So avoid using the maximum aperture as much as possible, and use a tripod for fixed shooting if necessary.

Hand-held shooting. Yes Minimum shutter speed.

Many zoom lenses without optical anti-shake function are large in size, long in lens barrel and poor in hand-held shooting stability. If the shutter speed is a little slow, the definition may decrease. So, under what circumstances is hand-held shooting allowed? According to years of shooting experience, the shutter speed when holding a camera should not be lower than the number of "short-end focal length+long-end focal length" divided by the reciprocal of 2, that is, 28-70 RAM lens should not be lower than1125 seconds, and 28-200 mm lens should not be lower than11second.

Composition should not rely too much on zoom.

The zoom lens can easily select the picture by changing the focal length, and it is also easy to develop the inertia of shooting in a fixed position. Pay special attention to this problem when using a large zoom lens.

Adjusting the picture by changing the focal length is not a real composition. For a photo with strong visual effect, perspective and angle are very important. When shooting, in order to achieve the necessary perspective effect, it is necessary to adopt the appropriate lens focal length and get the best angle by moving the camera. Because there is dust and water vapor in the air, you should be as close to the scene as possible when shooting. For images of the same size, shortening the shooting distance is clearer than using a telephoto lens.

Choose the right hood.

The optical structure of zoom lens is complex, there are many lenses, and the stray light is more serious than that of fixed focus lens. When shooting, a suitable hood should be used to avoid stray light outside the shooting range from entering the lens. It should be noted that zoom lenses with different focal lengths should be equipped with different hoods. Therefore, the coverage angle of the hood should be considered when purchasing a zoom lens. Some zoom lenses are equipped with original hood, which can change the shading range with the change of viewing angle and achieve good shading effect at various focal lengths.

Focus carefully

Zoom lenses are more difficult to focus than fixed-focus lenses. Because the maximum aperture of the zoom lens is small, the scene in the viewfinder is dark, and it may be out of focus if it is not careful. In addition, when the focal length of some lenses changes, the focus will also drift and need to be refocused.

Just like focal drift, some zoom lenses will change their aperture value when their focal length changes, which needs to be corrected in time.

The use of cameras

Stabilize the machine

1, it is best to hold the camera with two hands, which is definitely more stable than one hand, or use something that can be supported by you or prepare a camera tripod. In any case, it is to minimize the shaking of the picture, and it is the most taboo to shoot while walking, which is also the most common mistake. This shooting method is only used under special circumstances. It must be remembered that the stability of the picture is the first requirement of dynamic photography.

2. Keeping the picture stable is the most basic and important requirement for shooting. Whether it is pushing, pulling, shaking, moving, leaning, tilting, zooming, etc. We always work around how to keep the picture stable. The main factor affecting the stability of the picture comes from the stability of the photographer. Mastering the correct method of holding a camera is a basic skill for every photographer. Only with excellent basic skills can you operate freely when shooting and shoot high-level video works.

Fixed lens

1. Simply put, after the lens is aimed at the target, shoot at a fixed point, instead of zooming in and out or sweeping up, down, left and right. Set the size of the picture, and then start recording. Usually, the fixed lens is the main shooting mode, and there is no need to do too much zoom action, so as not to affect the stability and change of the picture, that is, the size and depth of field of the scene are changed by the difference of the viewing size or angle and position.

2. To put it simply, when shooting a panorama, the camera leans back a little, and when you want to shoot a part, the camera leans forward a little. If the position changes, such as the side, height and lower position, the effect will be different and the picture will be richer. If you can't get close because of the venue, of course, you can use the zoom lens to adjust the picture to the size you want, and the adjustment range can be slightly smaller.

3. But remember not to stand at a fixed point and zoom in and out with a zoom lens, which is a common problem in many V8 families. Using more fixed lenses when shooting can increase the stability of the picture. When shooting one picture at a time, connect pictures of different sizes and make the pictures bigger and smaller with less zoom. Unless you fix them with a tripod, long-distance zooming will definitely lead to picture jitter.

Shooting skill

1, I believe you have encountered a picture that can't take a panoramic view of the scene. At this time, everyone must scan the camera from right to left or from left to right, which is one of the advantages of the camera. But when many people do this action, the picture often swings from side to side or is fast and slow. Anyway, it looks very unsmooth. These problems mainly occur in the wrong way of body rotation, or the rotation angle is too large, which leads to hesitation and cannot be achieved overnight.

2. The correct way is to take the waist as the dividing point, and the lower body does not move the upper body. Just like when you want to cross the road, look around to see if there is a car coming. It is reasonable to turn your head left and right below your shoulders. For example, if you want to shoot a scene, you need to scan from point A to point B. First, turn your body towards point B, then turn your upper body towards point A. At this time, the camera is facing the direction of point A, then press the video button to record for 5 seconds, and then slowly scan back to point B. After positioning, continue recording for 5 seconds, and then turn it off.

3. Many people will ask, how fast is the scanning speed? In fact, there is no certain standard for this. It depends on the richness of the scenery in the range you want to scan. If you shoot a static scene, the speed can be faster, but the principle is to see the content clearly. If the framing content is dynamic and rich, the speed can be slower. Of course, these methods are only for reference when shooting. The most important thing is to practice and experience more to really understand the truth.

Basic shooting skills of camera

1. Familiar with the equipment

There are always accidents in life, so whether you can make the most timely response and adjustment accurately and quickly in actual operation depends on your usual understanding of the equipment.

parallel

If there is no special artistic requirement, we should try to make some geometric edges in the picture parallel to the lens frame, that is, "horizontal and vertical". This geometric edge is sometimes the ground, sometimes the desktop, and sometimes the roof edge.

3. Hold the screen steadily

Usually, you can do this exercise at home: hold things high, but still keep them stable. If the degree of hand shaking during shooting seriously affects the visual effect of the video, then even if the selected content is wonderful, it will always make people feel imperfect.

4. Learn to divert attention

Shift the focus: find two objects in different positions in your frame, then practice shifting the focus from one object to the other and then back again.

Application: For famous scenic spots, if you shoot directly at them, the lens will naturally lack vividness. At this time, the lens can naturally turn to the object to be highlighted through a moving object, which is equivalent to bringing this object into the picture.

Looking for an angle

Different objects have different suitable shooting angles in different situations, and such corresponding methods are generally regular. For example, it is recommended to choose prone shooting and close-up shooting when shooting food; It is more suitable to look up by patting the fallen flowers. Therefore, we should usually shoot more different kinds of things and accumulate experience in shooting angles.

6. Small animals

Presumably, people who like filming will not refuse to let small animals enter the country. Their participation not only makes the video more lively, but also adds a little interest to the video content. If people and animals can interact, they will certainly achieve more loving results.

Step 7 make up a story

Try to shoot several different pictures, expand the association and connect them into a complete story. This is more conducive to the development of photographer's thinking and even strengthens the connotation of video.
