How does the camera capture?

How to realize the capture function of surveillance camera

1. The surveillance camera with SD memory card is stored on the SD card, and this snapshot is triggered by the camera program.

2. Captured by the video recorder and stored in the video recorder.

3. It was captured on your computer through the computer client.

4. It was captured on your mobile phone through the mobile phone client.

First, hold the camera steady.

It is best to hold the camera with both 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. It is the most taboo way and the most easy mistake to make while walking. 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.

Second, fix the lens.

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 screen size and start recording.

Usually, the fixed lens is the main shooting mode, so as not to affect the stability of the picture. The change of the picture means changing the size and depth of field of the scene with different framing sizes or angles and positions. Simply put, when taking a panoramic view, the camera leans back a little, and when you want to take a part, the camera leans forward a little. If the position changes, such as side, high and low positions, the effect will be different.

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 you take a picture at a time, the pictures of different sizes are connected together, so you should not use zoom to make the picture bigger and smaller. Unless it is fixed with a tripod, long-distance zooming will definitely cause picture jitter.

Four basic methods of capturing action in photography!

First, use the correct autofocus mode.

How to use autofocus correctly to capture fast motion is the first and most important step to capture excellent shots of moving subjects. Each camera has multiple autofocus modes. They have different names depending on the manufacturer, but you can see the following on any camera:

Focus lock: after you get the focus, the focus will not change until you take a picture or change the focus position.

Stay focused. The camera will constantly adjust the focal length with the movement of the subject.

Manual focus. Fast action shooting is not recommended.

Second, return the button focus.

Paying attention to the back button is more than just setting the camera. You can use the button on the back of the camera instead of using the shutter button to focus. Back button focusing seems counterintuitive, because autofocus seems to go hand in hand with pressing the shutter button. However, there are several good reasons to use this focus, especially when capturing fast motion.

When you set the camera to continuous autofocus mode and use the shutter button to activate autofocus, you can press the shutter button while following the subject to get a perfect shooting effect.

Third, automatic ISO

In this case, if the subject is blurred (unless you try to capture motion blur), good composition will be meaningless (therefore, faster shutter speed is needed). This usually means using a higher ISO value, especially when shooting indoors where the light is weaker than outdoors.

Automatic ISO can save shooting time and set minimum shutter speed and maximum ISO. Most modern cameras can provide excellent results up to ISO6400, while still retaining enough colors and details.

Fourth, aperture priority shooting.

If you need a fast shutter speed to shoot, why not shoot in shutter priority mode? Because automatic ISO can give you the ideal effect.

Capturing skills of mobile phone photography

With the increasing resolution of mobile phone camera, professional lens and editing applications are increasing, and mobile phone photography is more popular and concerned by the public. Although the professional level of mobile phone photographic equipment is not enough compared with cameras, it is also portable in mobility, but it also gives many photographers a new choice.

Point 1. Composition should have a sense of hierarchy.

Composition is very important in photography, so you need to choose a good position, because it can support the background of your photo. For example, in the background of heavy traffic, it will be better if there is only one person in the photo as the foreground.

It is difficult to have time to fully consider the master-slave relationship between foreground, middle scene, background and subject when taking snapshots. At this time, you can use a large aperture to combine reality and reality to make the picture more layered.

The second point. Try to simplify the background in composition and learn to use black and white special effects.

One advantage of shooting street scenes with your mobile phone is that it won't attract attention, because you can pretend to listen to music, watch TV dramas or brush WeChat. When you photograph strangers in the street scene for the first time, you may find it a little difficult, but if you are lucky enough to capture their daily life, your photos will be full of life and become very real.

When taking snapshots in the street, the environment may be chaotic. Try the classic black and white photos in traditional optical photography. For shooting in complex environment, black and white photos can make the background of photos more concise and will not dominate.

Point 3: Try different shooting angles and learn to use continuous shooting mode.

Moving objects are usually difficult to capture with a lens. Because the mobile phone is unstable or the target moves rapidly, the image is blurred. When you press the shutter, a good picture may have disappeared into the lens. At this time, you need to grasp the continuous shooting mode of the mobile phone. As long as you press the shutter button, the phone will take a series of continuous shots without missing any details, and then you can choose the best photos from them. You can also look for different shooting angles to break the oneness of the picture. Try from multiple angles, such as front, side, head-up, looking up, etc. This will add interest to your photography.

Point 4: Composition depends on the sense of space of the building.

Street photography not only photographs people, but also the buildings in the city. With the help of architectural design sense and lines, we can learn to shoot as much sense of extension or depth of space as possible. You can photograph the whole building, the skyline or a part of the building.

Proper use of words as visual focus can light up the picture. At the same time, as a scale contrast with architecture, people can also highlight the sense of space of architecture or city.

Fifth point

Is the snapshot composition technique mentioned above very practical? But we should not only learn shooting skills, but also have high-performance shooting artifacts. No matter how high the technology and equipment are, the photos taken have no aesthetic feeling. To be a mobile phone photographer, you need a glory V9 that can shoot in seconds. The third generation of double camera makes you stop waiting, take a beautiful moment in the second, and take a youthful personality.

According to the data of Glory Lab, the startup speed of Glory V9 camera is faster than that of iPhone7Plus 15.3%, and the shooting speed of normal mode camera is increased by 4.3%. Glory V9 is not only quick, but also good. The above pictures were taken by Glory V9. Isn't it beautiful? It can be called a "photo artifact". Adopt dual12 million pixel black-and-white+color lens, cooperate with the third generation dual-camera technology, brand-new algorithm and the first camera mode, and put an 8 million pixel beauty lens in front, which will bring better imaging effect and perfectly control the bright spring and beautiful you.

Professional photographers can use professional photography mode, and can adjust parameters such as aperture and shutter to shoot large scenes. If Xiaobai can't play with the depth of field, he can use the large aperture mode of Glory V9, take photos first and then focus, easily blur the background and present fantastic photos. There are also interesting functions such as 3D creative shooting and panoramic VR camera shooting. It is a good choice for people who are creative, like dreamy background and are keen on shooting city scenery.

How to capture photos?

first

For DC consumers,

AF and MF have little effect on snapshot.

Because MF is nothing more than eliminating the focus of the camera.

In the continuous shooting mode,

Camera autofocus is generally not good.

Even if AF works in continuous shooting.

As long as the theme is still life

It will not be much different from MF.

If it is a moving object, AF is obviously slower than MF.

But under MF

Pictures of moving objects will be out of focus.

It says snapshot below.

In fact, the essence of snapshots is no different from that of continuous shooting.

They are all large aperture compensation and high shutter.

You said you were telephoto.

Then I'll give you some advice

1. If you want to take a snapshot, don't consider automatic mode. M file is king. Chips will never be as advanced as human brains.

2. Snapping requires a high shutter. Therefore, in the case of sufficient outdoor light, the shutter should be opened at least above 1/320. Of course, if conditions permit, the higher the better.

3. High shutter will bring low exposure. Therefore, a large aperture is necessary. Even outdoors, the aperture should not be larger than F4.0, which requires that your telephoto should not be too large. Because the larger the multiple, the smaller the aperture, which is fixed by the firmware and cannot be changed.

Therefore, I personally suggest that the magnification should not exceed 4x, and it is best to be as close as possible to the subject and as close as possible to the macro.

Final summary:

Minimum requirements for DC snapshot: M file, MF, shutter 1/320 or above, aperture below 4.0, ISO 320(400) or below, and close-up is preferred.

Children's Photography Skills: How to Capture?

1. Capture the most natural moments with snapshots.

Children of different ages have different reactions to the camera, but they usually have one thing in common-they don't look at the camera as you wish. Actually, we really need them to look at the camera, so is it worth pressing the shutter? Since we want to record their lives, we should capture their natural moments more. So, you can try to take a snapshot instead of letting them look at the camera and take it again. Instead, we can wait for them to get along with their families or play at home and shoot quietly beside them to capture their most natural moments, so as not to take some stiff or far-fetched photos.

2. Let the light speak for your photos.

Learn to use light to make photos look better. Observing the light is the best start. You can go to different rooms at home at different times of the day, and pay attention to when the light falls on the table, spreads to the blinds, softens and becomes more dazzling. Observe when the light shines on the bathtub and when it illuminates the children's room. You can also choose to take a lunch break after the children are tired of playing, wait for the light to enter the room through the window and take some photos of their sweet sleep.

3. Pay attention to increasing the shutter speed

I believe all mothers have a deep understanding of their children's activeness. Therefore, in order to condense the moment of their action, a relatively high shutter speed is needed to achieve the effect of "freezing" smoothly. If you use a general consumer camera, it is recommended to choose sports mode for shooting. If monocular or micro-monocular cameras are used, it is recommended to choose manual or shutter front mode, and try to ensure that the shutter speed is not lower than 1/250.

Capture gestures

In figure photography, the hand is often called the second face of a person, which shows the importance of the hand. The hand is a tool for most people to communicate with the outside world except the five senses. Therefore, for a long time, the meaning of gestures has become more and more abundant. Through gestures, people can even judge their behavior, state, mental outlook and even psychology. Therefore, photographers sometimes capture a vivid gesture, which is no less than capturing a vivid facial expression, and can also receive an implicit effect that is intangible than tangible. As shown below, the complete gestures and expressions of the characters, combined with vivid gestures, show the colorful inner world of the children.

5. Pay attention to the angle of lens shooting and see the world from the perspective of children.

Whether a photo is beautiful usually has a lot to do with its background. So if the scene environment is beautiful, you can absorb as much background as possible when shooting. However, many parents are also used to standing and taking pictures of their children. Because children are shorter than us, standing to take pictures will make the shooting angle of the lens tilt downward, which will lead to most of the background of the photo becoming the ground and wasting the beautiful background. Therefore, when shooting, try to squat down and make the angle of the lens flush with the child's eyes, so as to absorb more background and enrich the background of the photo.

In addition, when shooting, we can even squat down a little and shoot the camera up slightly. The photos will have a feeling that children look at adults and the world, and the effect will be unexpectedly good!

6. Moderate exposure

This is what I think is very important. Most baby photos want to reveal the feeling of cuteness, innocence and hope, so most of them use bright photos to present such an atmosphere. Because of the principle of camera photometry, if you choose weighing photometry, when the picture is full of white or light-colored objects, the overall exposure will be lower than that seen by naked eyes, so please be sure to add exposure compensation (Ev). The author's habit is to add the values in the range of +2/3 to+1, and then adjust them after shooting. It is not a big problem that the background is slightly overexposed or dead white. The baby's face must be exposed correctly, otherwise the whole photo will be dull and tasteless. If the camera has built-in highlight tone priority (D+) function, it is also recommended to turn it on, which can make the details of highlights better and reduce the appearance of dead white.
