I have to say that the shooting ability of mobile phones is really powerful now, and the popularity of smart phones makes it easier and easier to take pictures. The camera function of mobile phones is also one of the most competitive places for major mobile phone brands, and even many mobile phones specialize in taking photos as a selling point.

The biggest advantage of taking pictures with a mobile phone is portability. We may not bring a camera when we go out every day, but at least we will bring a mobile phone. You can take pictures when you meet your favorite pictures. For most people, if you don't take out your camera to take pictures, even if you usually have a camera in your bag, you may have to do some ideological struggle to take it out of your bag, and the picture will disappear, so it doesn't matter whether you take it or not.

Another powerful function of mobile phone is immediacy. Many applications in the mobile phone can help us to quickly post-process the photos taken. There are not only high-end professional Photoshop and Lightroom in the app Store, but also countless one-click filter software. After the photos are processed, we can share them on social networks immediately, so that more people can see our works.

Although many cameras have added wireless transmission function now, it still needs one more step, and it still needs to be transmitted to the mobile phone.

But can mobile phones surpass cameras? Yes, but not all. At least, mobile phones have long surpassed a camera type that once existed and was all the rage. Small DC, commonly known as card machine, is almost unheard of now, because it has disappeared and has been surpassed and replaced by mobile phones.

More than a decade ago, even buying an entry-level APS-C SLR camera may be a big investment for most people, but for most daily shooting users, a relatively professional SLR doesn't make much sense at all. As a result, various manufacturers have introduced entry-level card cameras, which are as small and light as current mobile phones, and even attract young users with fashionable shapes and colors.

However, their shortcomings are similar to those of current mobile phones, such as lack of active control, and the sensor is too small to change the lens. However, because the body space of DC is relatively more spacious than that of mobile phones, most of them have built-in zoom lenses, which can achieve at least 3 times or more optical zoom.

Although mobile phone photography is quite powerful now, it can almost completely meet the needs of daily photography, but it is still a long way from professional photography. Mainly affected by the following points.

1, control right

The sign of professionalism is mastery of control. We can give all the shooting parameters to the shooting equipment without actual control, but we can't do without control. The biggest feature of professional cameras is complete control. Using a professional camera, we can set all shooting parameters freely, from the aperture shutter sensitivity of the three elements of exposure, to the setting of white balance, to the exposure compensation, and then to the focus control. Everything can be controlled by self-awareness, and you can shoot the picture you want with your own skills and experience.

Although some mobile phones are now partially open to control, their influence is still very limited. Most mobile phones are still limited to hand-shooting, which is not serious for daily shooting, but has a great influence on creation.

2. Hardware

There is no way to change the lens of a mobile phone, even limited by the size of the body, and even optical zoom is difficult to achieve. As for the digital zoom promoted by some mobile phones now, people who know a little bit know that this is a gimmick. Nowadays, many mobile phones are integrating multiple lenses to realize the change of focal length. In the early years, Kodak's DC realized the optical zoom of ultra-thin body with dual lenses.

The particularity of interchangeable lens camera lies in its expansibility. We can shoot different objects by changing different lenses or adding different accessories. We can shoot streets with a focal length below the standard lens, landscape buildings with a wide-angle lens, portraits with a medium telephoto lens and wildlife or sports photography with a telephoto lens. Different focal lengths determine different themes that can be adapted. For most mobile phones, all they have is an equivalent wide-angle focal length.

The quality of mobile phone lens and camera lens is also incomparable.

On the image sensor, the mobile phone really has no advantage. Also limited by the size of the mobile phone, the size of the physical sensor of the mobile phone will not be too large, not to mention those mobile phone manufacturers who put the sensor into the mobile phone to spell data but can't sell a few. At present, the sensors of most popular mobile phones on the market are generally small. As the saying goes, the bottom layer presses people. Even the 1 inch sensor of the most commonly used compact camera on the market is much larger than that of the mobile phone, not to mention the size of Quan Huafu or even the medium format sensor.

The mobile phone is superior to the camera in processor. Most mobile phones have built-in very powerful processors, which can use more advanced algorithms to arrange pixels more effectively and make the imaging effect better. However, no matter how excellent the algorithm of the mobile phone is, it can only make the output on the original small bottom look better. Every photo taken actually seems to be equivalent to the internal processing of the mobile phone, so the so-called mobile phone is better than the camera, because people have already passed it.

However, if you are used to cameras, you will know the powerful possibility of taking pictures in the future.

3. Low light photography

Weak light is also the weakness of mobile phone photography. It can be said that the current mobile phones are all daylight machines, which will perform very well when the light is good. Mobile phones are not even inferior to cameras in looking at photos. But the performance in low light environment may not be so good.

This is also limited by the sensor. A larger sensor means that a unit pixel receives more light. At the same resolution, the pixels per inch of the photosensitive elements in the larger frame are lower than those in the smaller frame, which gives the sensor manufacturers more space in electronic circuits, so in the case of high ISO, the large frame will perform better than the small frame. However, for small sensors, a single pixel can get fewer photons and less information. In order to compensate it, it is necessary to increase the electrical signal, which will produce noise.

So generally speaking, when shooting in low light, there is no advantage for the mobile phone to face the camera, let alone the super night scene. The night shots of most mobile phones will be horrible as long as they are slightly enlarged. There is no problem watching entertainment on the mobile phone, but it can't be used as an output.

At present, limited by hardware such as lenses and sensors, mobile phones are far inferior to cameras in imaging quality and control. But to be honest, not everyone needs professional creative control and print quality. For most users who just look at photos on the mobile phone screen and just need to share photos on social networks instead of professional output, mobile phone shooting is powerful enough.

It can be predicted that mobile phone shooting will get better and better in the future, and it will surpass today's cameras one day. Just like twenty years ago, we never thought that a small mobile phone could achieve so many functions. However, while considering the black technology of mobile phones, don't forget that the development of technology is synchronous, the manufacturing technology of cameras will never stagnate, and cameras will always have their meaning of existence.

At every stage, every kind of equipment has its meaning of existence and adaptive user groups. Finding the most suitable equipment for us is the key for us to take good photos.
