Is 5800W photography autofocus?

The following skills are summarized by combining relevant information and taking photos at ordinary times, hoping to help you.

Although the 5800 has only 3.2 million pixels, the carl zeiss lens with 3.2 million pixels has a good photo effect. After all, not a professional digital camera.

1. Everyone may know that this lens has autofocus, that is, when you shoot an object, it is actually a wrong operation to press the camera button at once, so the shooting effect will be blurred.

The correct way is to press the shutter button slowly, not the bottom button. When the lens is autofocused, it will beep, and the box on the camera interface will turn green, indicating that the autofocus of the camera has been completed, and then press the shutter button to the bottom to take pictures.

This is the most basic and easily overlooked skill to take pictures with a mobile phone with autofocus function.

2. The photos taken are also inseparable from the following external factors: whether the light intensity is strong, and whether the camera angle uses digital zoom.

Light: Good light is very important to take good photos.

Anyone who knows something about light and mode adjustment knows that light is an important factor affecting imaging quality. Like cameras, mobile phone cameras have high requirements for light, and lighting is more important because the lens of mobile phone cameras is small. Therefore, if you want to shoot a good work, you must choose good lighting conditions and try to avoid shooting in the back light. Some mobile phones can meet the light source through external conditions, and can also be adjusted through the built-in auxiliary functions of the mobile phone:

① Adjust the brightness. Many mobile phones can adjust the brightness of the camera and can be used when the light is insufficient.

② Night mode. It can be used not only at night, but also in night mode in case of insufficient light during the day to obtain better brightness. It's just that it takes a long time to take a picture after turning on this mode. If your hands shake slightly, the photos you take will have double images.

3 Flash. The flash on the mobile phone is actually a bright LED light, which can effectively fill the light when turned on, but the effective distance is relatively short, which is suitable for close-up shooting.

(4) At night or when the indoor light is insufficient, turn on the night mode or flash as much as possible (not all mobile phones have functions), and the effect will be slightly better; The best way is to fill the light, add a desk lamp indoors, turn on the light outdoors, or be close to the light source; Flashlight is also a good supplementary light source, which is helpful when the light is dim.

⑤ The light is strong enough, and the shooting effect is naturally good. However, the light will not be transferred by personal will, so it is necessary to change the shooting angle at any time and pay attention to the irradiation direction of the light. You can follow the light and try to make the subject naturally illuminated by light.

Generally speaking, the side light can better highlight the texture of the object, so we should make full use of the side light. When backlighting or side backlighting, you can consider blocking with objects. If it is impossible, cover the camera with your hand to reduce the influence of backlight. Attention should also be paid to shooting under strong light. Never shoot in the glare with the lens of your mobile phone.

Shooting Angle: When you always feel unsatisfied when shooting an object, you may wish to shoot from another angle, which may have unexpected effects.

Digital Zoom: Digital zoom, also known as digital zoom, is called digital zoom in English. Digital zoom is to enlarge the area of each pixel in a picture through a processor in a digital camera, so as to achieve the purpose of enlargement. This technology is like enlarging the area of a picture with image processing software, but the program is executed in a digital camera. Some pixels on the original CCD image sensor are enlarged by interpolation, and the pixels on the CCD image sensor are enlarged to the whole picture by interpolation algorithm.

Different from optical zoom, digital zoom is the change of the vertical direction of the photosensitive device, which gives people a zoom effect. The smaller the area on the photosensitive device, the user can only see part of the scene visually. However, because the focal length has not changed, the picture quality is worse than normal.

So when you shoot an object, try to get close to it instead of zooming in at a distance, which will be much better.

3. The posture of holding the mobile phone when taking pictures is also very important: users who like to take pictures with their mobile phones may feel deeply that the camera phone is only that big and its weight is less than half of that of ordinary traditional cameras. No matter how good the light is, it will be ugly if you are not steady when shooting. In particular, CMOS cameras are more sensitive, and slight vibration will directly affect the imaging effect. When shooting, the right hand holds the camera at the subject, and then the left hand holds the right hand to keep it stable. Because the response speed of the mobile phone is not as fast as that of the camera, it is not taken immediately after the camera shutter is pressed, but only when the shutter sound rings, so it is best to set the shutter sound when taking pictures, and the mobile phone must be held firmly when taking pictures. Especially when you press the camera function key, if you move at this time, the picture you take may be blurred, so you must keep a steady posture until you take a picture.

Some of the above skills are summarized by me according to relevant information and taking photos at ordinary times, hoping to help you.
