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 don't need 2-megapixel photos, so using a lower resolution allows you to take more photos and the camera can process them 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.
