How to use digital camera to take pictures correctly

Single-lens reflex camera has entered the era of autofocus. For ordinary photographers, the performance and usage of some high-end cameras are much simpler. In this way, as long as we choose a good scene, construct a good picture and gently press the shutter, we can complete a more difficult shooting job.

Of course, this kind of camera is rare in the hands of some photographers, so we should learn the basic usage of some basic types of cameras.

_ I'm so annoyed that I can't hold it any longer.

The camera should be placed in the right position.

1 eye level

When shooting, stand upright, lift the camera to the eye position and shoot along the horizontal direction, which is also called prone shooting.

This method is used the most, the picture is natural, and the viewer has no strange feeling. In addition, because of the horizontal angle photography, the building has no sense of inclination, giving people a sense of stability.

2 waist flat position

Standing at the height of the waist and shooting along the horizontal direction is called waist level. This is a common photographic method for people in the heyday of binocular reflex camera to look at the focal plane from above. Now, bending the knee and waist position have the same meaning.

This height is very useful for photographing children. If you look down at the height of an adult while standing, the child's head will be exaggerated and an abnormal picture will be obtained. Using waist photography, the child reflects normal.

3 low position

Refers to the camera close to the ground, as far as possible in the horizontal direction aimed at the subject of photography.

The objective objects that people see from habits, such as from the height of the ground, will have a refreshing feeling.

Correct use of shutter

1 When using the shutter, the first thing we should pay attention to is that the shutter speed must be adjusted to a fixed gear, and it cannot be used between two gears like an aperture.

Single-lens reflex cameras are all wound and the shutter is wound at the same time. So when winding the film, you must pull the wrench to the end before you can press the shutter. Some cameras (Nikon FM2) have a quick door lock function after the wrench is reset, so only when the wrench is turned to the working angle can the shutter be pressed.

Cameras with separate clockwork and shutter clockwork (such as Seagull 4A camera, which reels film with a crank) need to tighten the shutter separately, so that it can be exposed under pressure. When pressing the shutter, the arm muscles should be kept relaxed and not shaken. When using the central shutter (such as the camera of Seagull 4A), the speed must be adjusted first, and then the shutter must be tightened. This procedure must not be reversed.

After shooting, release the shutter and set it to position B to prevent the shutter mechanism from being damaged due to long-term stress.

Correct adjustment of aperture

1 During shooting, when we adjust the aperture, we should dial it step by step. When adjusting the stagnant aperture, every time you hear a "click" sound, it means that it is the correct gear of a certain aperture. Be careful not to rotate the aperture adjusting ring quickly and repeatedly, even if it is a non-stagnant aperture, it should be gently turned.

When using the aperture, you don't need to be limited by the gear, that is, you can use it by adjusting the aperture to between f/8 and f/ 1 1.

After shooting, the aperture should be opened to the maximum to prevent aperture fatigue and help extend the service life of the camera.

Correct use of automatic exposure camera

1 Automatic exposure cameras have different automatic exposure modes (also called exposure modes). Now some cameras can even provide as many as 15 exposure modes. There are three common automatic exposure cameras: aperture priority, shutter priority and standard procedure.

The use method of automatic exposure camera is basically the same as that of ordinary camera. Just before shooting, adjust the aperture or shutter speed according to your camera automatic mode before shooting.

Correct use of selfie

1 Different types of cameras have different automatic shooting methods. Seagull 4 series camera, first put the self-timer button on the board, and then press the shutter button to realize self-timer.

Seagull DF- 1 camera, pull the self-timer button, you don't have to press the shutter button, just press the button next to the self-timer to achieve self-timer. For Yasika FX-7 camera, only by tightening the shutter first, then pulling the self-timer button, and then pressing the shutter can self-timer be realized.

The average selfie takes about 10 second, so you need to master the duration when using it to avoid being in a hurry.

How to take pictures with a camera?

1, beware of framing errors. The optical viewfinder of an ordinary digital camera is paraxial. The scene seen from optical framing and the photo actually taken by the lens do not pass through the same optical axis. The worse the topic, the more obvious it is. There are often some in optical viewfinder.

The close-up compensation sign tells the photographer about the error. Using LCD to find views can solve this problem to a great extent. However, the resolution of LCD is not always proportional to the CCD of the camera. In my test, I found that the images seen on the LCD of many cameras can't be completely consistent with the photos in the clip. If you are very concerned about whether the scenery photos you have taken meet the requirements, you'd better have a look for yourself.

2. Don't trust LCD too much. The convenience of a digital camera is that it can see the photos taken immediately. If you are not satisfied, you can delete it and shoot it again immediately. Of course, obvious problems such as composition, framing and lighting can be found immediately, but focusing is not good.

Small faults such as collimation and camera shake may not be visible on the LCD screen with low resolution, so there is no need to be superstitious about LCD. Just like using a traditional film camera, the important prerequisite for taking a good photo is to hold the camera steady and focus on it. We found that some cameras have some errors in LCD brightness and color reproduction, and the shooting results seen on LCD are quite different from the images finally seen on computer monitor. After careful comparison several times, users can adapt to this difference.

3. In order to ensure the stability of the camera, the shutter lag of digital cameras is often as high as 1 second. When using a digital camera, many people put down their hands holding the camera after pressing the shutter. As a result, the camera was moving when the shutter was opened, and the blurred picture was obtained. You can shoot when you watch with a liquid crystal display.

It's convenient, but when the hand leaves, it will shake unconsciously, which is often not noticed by the photographer. So if your digital camera has an optical viewfinder, use it as much as possible. Putting the camera close to the head can effectively reduce the jitter-and you will get an extra bonus: the battery of the camera can last longer because the LCD screen that consumes a lot of power is turned off. Try to use a tripod or other bracket when the light is bad to ensure that the camera will not shake when exposed for a long time.

4, accurate focus, now digital cameras will automatically focus, but the machine can not do everything for you. Focusing of digital camera

The point is generally located in the center of the picture, which means that it will adjust the focal length according to the position of the object in the center of the picture. If your composition is just off-center, you need to aim the camera at the subject first, press the shutter half-way, and then re-compose and shoot. When the light is weak or the contrast of the subject is not great, we find it difficult for many cameras to find the correct focus. At this time, we can focus on an object with the same distance from the camera and large contrast, and then change the composition to shoot.

5. The resolution is appropriate. Users often like to choose high resolution when buying digital cameras, and they also like to shoot with the highest resolution of the camera. In fact, many applications (such as web pages, photo printing, etc. ) You don't need a 2 megapixel picture. At this time, more photos can be taken with lower resolution, and the camera processing speed is faster.

6. With the best aperture, digital cameras often have lenses with large aperture numbers. In automatic mode, camera programs also tend to use a larger aperture to shorten the shutter time and prevent vibration. But the common sense of photography tells us that the camera lens can usually take the best photos when the distance from the maximum aperture is reduced by about two levels. Therefore, if you are most concerned about the image quality, you can use the aperture priority automatic exposure, and reducing the aperture from the maximum to a smaller one can often get better results. Another problem brought by large aperture is small depth of field, that is, the clear range before and after focusing is small. Using a small aperture can enlarge the depth of field, which is especially obvious in close-ups. If the camera does not have the aperture priority function, you can try to improve the brightness of the environment, let the camera automatically choose a smaller aperture or use a flash, and the image quality will also be improved.

How to take pictures with a camera

Hello!

There are many ways to "take pictures with a camera":

1. Use the shoot button on the camera.

Most brands and models of cameras are equipped with shooting buttons, which can be shot by pressing them.

2. Use some camera application software, which has the function of taking pictures.

For example, "happy photo stickers"

, "camera video expert" and so on. , online search, it is easy to find the address of free download.

3. Use QQ video chat function.

In the QQ video chat window, there is a "take a picture" button.

4、Windows

XP system also has a camera function.

Open "My Computer", double-click the "Digital Camera" option at the bottom to open the "Photograph" window, with the "Camera" taskbar in the upper left corner and the pictures taken by the camera in the middle. Click the "Take Photo" button to capture the current camera image, and the photo will be displayed at the bottom of the window. These photos will be automatically saved. As long as it has not been deleted, you will see your own photos every time you open the window. Right-click the photo to preview and copy it.

If you want to master the photography skills of digital cameras, you need to learn the operating principles and methods first, then you need to master the composition and light of photography, and constantly improve your photography strength in repeated shooting exercises to shoot amazing works. Next, some skills are mainly explained from the aspects of equipment principle and operation, shooting composition, light application, etc., to help everyone understand photography skills more systematically.

First, the practical principle and operation of digital camera

1. photo settings

Some camera settings may have affected the final photo or workflow before the shooting activity begins. Among them, the photo setting is the first thing you need to consider. The size and quality of the final photo can be selected in the early stage according to the use, and the parameters can be adjusted according to the specific size and resolution requirements of platforms (such as outdoor advertisements, web pages, books and personal exhibitions), viewing equipment (such as computer monitors, projectors and mobile phone screens) or other uses (such as quick preview and print proofing).

Generally speaking, JPEG file is a relatively small compressed file image format, which provides options from small to large, such as S, M, L, and other options with different image quality, such as zigzag and smooth icons. The largest and highest quality file format is usually lossless source file RAW format, and each brand corresponds to a different format name (for example, Canon brand corresponds to the RAW file format of .cr2), which has the most complete image information and the largest post-processing workspace. If the final image requirements are not clear, it is recommended to choose JPEG+RAW format combination when setting.

2. Exposure combination and application

The basic tone of a photo is closely related to the exposure, but before actually adjusting the exposure, everyone needs to be clear about the concept of dynamic range. In fact, the performance of photosensitive elements in different bodies is very different. It can be understood that the camera can capture the range of light and dark in one shot. This means that the dynamic range is not only limited but also different for different cameras.

However, the range of light and shade for human eyes to watch nature is much larger than these ranges, so the light and shade effect of photos taken by ordinary digital cameras at a time is not necessarily consistent with the effect of watching the actual scene with the naked eyes.

You can get different exposure and control other effects by adjusting the combination of aperture size, shutter speed and sensitivity. Among them, the aperture controls the light entering the aperture of the camera, the shutter controls the time when the light enters the camera, and the sensitivity controls the speed or sensitivity of the photosensitive element inside the camera.
