What is the basis for choosing a mobile phone camera tool?

With the rapid development of mobile phone camera, the size of the sensor is increasing, and the multi-camera technology improves the actual focal length of the lens. To tell the truth, many friends know that taking pictures with a camera is better than taking pictures with a mobile phone, but when taking pictures, they always wonder: I just take a picture. What's the difference between a mobile phone and a camera?

The core of any photographic equipment is three parts: the lens part for collecting light information, the sensor part for recording light information, and the processor for processing image information. The difference between a camera and a mobile phone lies in these three parts.

As long as it is a photo setting, it is composed of three cores: lens, sensor and processor.

Although the mobile phone is developing rapidly now, as a lightweight communication tool, it still can't accept the increase in size and weight. However, human optical technology is limited by physical factors, and it must have a larger volume in order to do better at this stage. Therefore, the camera is essentially a photographic equipment for shooting. Although the mobile phone takes good pictures, it still cannot replace the camera in the field of picture shooting.

Let's talk about the five advantages of cameras compared with mobile phones.

1, high resolution

The camera sensor is larger in size. At present, most card machines have been upgraded to one-inch sensors, while SLR and micro-single cameras are generally APS-C format, and full-frame cameras are becoming more and more popular. Therefore, the camera not only has higher pixels, but also has better actual imaging effect. Perhaps in daily life, we can't see the difference when shooting during the day, but after zooming in, the camera undoubtedly has an advantage in detail.

At present, the biggest sensor of mobile phone is11.7, which is very different from APS-C.

The camera sensor is larger in size, and can use higher pixels, and the lens resolution is stronger. So if you really need large-size output, you must rely on camera equipment. On the other hand, once the shooting environment is not normal light or in extreme environment, the camera can still cope with its own sensor advantages and lens advantages, while the mobile phone is often difficult to cope with.

In extreme environment, the camera can maintain high resolution, but it is difficult for the mobile phone to maintain the shooting level during the day.

2, the lens advantage

Mobile phones are limited by size. Even if there is a breakthrough in multi-camera technology and optical zoom, it still cannot break through the physical barrier of the lens. For the lens, the camera lens can achieve a larger aperture and a richer physical focal length, so it can shoot more subjects and achieve better Jiao Wai blur.

Cameras can get better natural blur effect by virtue of the large aperture of the lens, but mobile phones rely more on algorithms.

Of course, it is more difficult for mobile phones to achieve telephoto. Although the mobile phone has optical zoom performance, compared with the camera, the focal length is still too thin, there is no wide angle, and there is no real telephoto. So if you want to take good photos, you still need a good camera.

Although the mobile phone has optical zoom capability, it is not as good as the camera in super wide angle and telephoto.

3. Tolerance advantage

Tolerance is another core factor that distinguishes cameras from mobile phones. Tolerance represents the dynamic range of photos. The camera is more tolerant, and the RAW file is more suitable for shooting scenes such as sunrise and sunset. The tolerance of the mobile phone itself is much smaller than that of the camera. Even if you shoot with RAW files, you will produce more noise when you adjust later. But with the camera, the camera itself has a better tolerance, which is beyond the reach of mobile phones. It can make shooting in a high light ratio environment simple and easy through various filter systems.

The camera is more tolerant, which is beyond the reach of mobile phones.

4. High sensory advantage

"The larger the size of the sensor, the better the image quality", this sentence is largely about the high sensitivity performance of the camera. When shooting at night, we need to use high sensitivity, at this time, the photos will produce a lot of noise. The bigger the frame of the shooting equipment we use, the less noise we produce.

The frame of the camera is bigger, and the photos taken at night are clearer.

In fact, it is not only high sensitivity, but also larger sensors have better exposure effect for a long time. When the camera is shooting with long exposure, it can shoot with low sensitivity, which will hardly add extra noise. However, on the one hand, it is relatively difficult for mobile phones to achieve long exposure, on the other hand, long exposure noise is easy to occur.

Not only is it highly sensitive, but the camera can easily achieve long exposure and better image quality.

Step 5 focus on advantages

Focusing performance is the core performance of a camera. The focusing performance of cameras has experienced decades of development. In the digital age, on the basis of traditional phase and contrast focusing, there are many different factions such as full pixel dual-core focusing and DFD focusing technology. The focus system of mobile phones generally adopts contrast focus, and a few mobile phones have full pixel dual-core focus, but compared with cameras, it is still difficult to deal with high-speed moving objects.

In the face of high-speed moving objects, cameras can track and focus, but mobile phones are difficult to do.

In addition, the mobile phone focusing system actually depends more on the large depth of field of the mobile phone. In fact, the depth of field of the mobile phone camera is very deep, and clear shooting can be achieved without too precise focusing. However, in case of night, fast moving objects, etc. The advantage of large depth of field focusing is not obvious. At this time, focusing on mobile phones often leads to problems.

Now the effect of mobile phone photography is very good, and mobile phone photography is developing rapidly. But mobile phone photography is a public-oriented photography function, and camera photography is a more professional photography tool. So if you just take pictures, the effect of the mobile phone is acceptable, but if you want to know more about photography or create photography, you still need a powerful camera as a tool.
