Why doesn t the dual camera of the mobile phone feel, it s like an ornament, is it really like this?

The dual camera in the phone is actually not very useful, and it really is, because if your phone is now a regular dual camera,You choose to shroud the secondary camera, either with your finger or with your own object, and you find that the pixels don't change. <>

The bicolor of the mobile phone is more used to coordinate the degree of light and darkness just like the two eyes of a person, we use one of our own eyes when we look at things, maybe your habit is to use the left eye or the right eye, but it is undeniable that our other eye plays a very coordinated role, if you don't believe it, you cover your eyes with one hand, you will find that your positioning of the object in the space is not so accurate, so it is inseparable from the three-place imaging it is inseparable from the two-color, our eyes are like this, and the mobile phone is also like this，If you want to shoot a more three-dimensional and clearer **, you can't do without the assistance of the second camera, but it hasn't reached that necessary yet. <>

There is only one main camera in the mobile phone, even if it is three cameras and four cameras, there is really only one main camera, and the other cameras play an auxiliary role, such as a depth of field lens, a lens with a larger aperture, etc., these lenses are to help the main camera achieve a better shooting effect, our mobile phone is matched with a double camera at the level of about 1,000 yuan, one is the main camera of 16 million, the other is the depth of field of 2 million, the depth of field of 2 million basically has no effect, Because you can't feel what pixels he has2 million pixels, it can be said that it is no different from the landline shooting, and it just plays an auxiliary role, and you can't feel its role. <>

The second camera of the dual camera, theoretically speaking, it should have a great effect, but because of the cost of the thousand-yuan mobile phone, the second camera cannot be too good, so it is more of a simple auxiliary role, there is no second camera, and there is no problem with the main camera alone to complete clear shooting,After all, 16 million pixels to meet people's basic shooting is no problem, and when it reaches 48 million, 64 million, the second or even the third camera will really play its role.

It shouldn't be a decoration.,Since the mobile phone has a dual camera,It should naturally have its use.,It's just to learn to use the operation.。

The dual cameras in your phone aren't really very useful, and if you cover the secondary camera, whether it's with your fingers or your own objects, you notice that the pixels haven't changed.

No, the results of the dual camera are much more realistic than the single camera, and there are a lot of nuances that you just don't notice.

Since there is a dual camera, and it can be kept all the time, it means that this has a certain effect, the dual camera looks useless, but compared with the previous single camera, you will find that the people and scenery shot by the dual camera will be clearer, and it will focus more on the people in the picture, and there will be more snowflakes like the single camera.

The dual camera of the mobile phone is not a decoration, although many mobile phones with four cameras or even five cameras nowadays always have a few cameras to "make up", but most mobile phones will be equipped with at least a main camera and a wide-angle lens, or a main camera and a telephoto lens. Lenses with different focal lengths are suitable for different photo scenes. In the case of the iPhone 8 Plus, the two cameras are a 26mm-equivalent main camera and a 58mm-equivalent telephoto lens.

Since the 58mm focal length is exactly 2x the 26mm focal length, the iPhone 8 Plus has a 2x optical zoom function. In other words, when shooting a long shot, you can switch to using a telephoto lens to zoom in on the long shot, so that the shot is clearer.

Some netizens will say that in the past, single-camera mobile phones could also be shot with zoom. In fact, otherwise, the zoom of a single-camera mobile phone is actually a digital zoom, and its principle is to enlarge the total pixels in the same proportion by cropping, and in the case of the total pixels, after magnifying 2 times, the image quality will be seriously reduced, and some details will be distorted.

As shown in the image above, the sample on the left is taken with the main camera and then zoomed in to 2x the size by equal proportions, and the image on the right is the sample shot with a telephoto lens with 2x light variation. A careful comparison will show that the ** shot with a telephoto lens on the right is clearer, and more details are retained in the frame. Telephoto lenses are not only great for shooting scenes from a distance, but are also great for shooting portraits.

Because the longer the focal length, the easier it is to shoot a natural bokeh effect, which can be used to highlight the person and make the portrait look more three-dimensional. Some mobile phones use a dual camera combination of main camera + wide angle, such as iPhone 11, which uses a 26mm equivalent main camera and a 13mm equivalent wide-angle lens. The purpose of a wide-angle lens is to have a wider field of view, which is more suitable for shooting landscapes, or to get more angles in indoor cramped environments.

When shooting portraits, the principle of edge distortion of the wide-angle lens can be used to shoot the effect of "long legs", so this lens is also very popular with girls.

In the past, when dual-camera phones were just popular, some mobile phone manufacturers used a low-pixel "depth of field lens" instead of wide-angle or telephoto lenses in order to save costs. The so-called depth-of-field lens is not involved in shooting, but is only used to measure the distance between the subject and the camera, so as to use algorithm simulation to achieve a better background blur effect. It's true that this depth-of-field lens is less useful, but it's not just a decoration.

Pretty much, it really doesn't have any effect for us ordinary people, it's just a decoration. Of course, if you have other needs, you should be able to use them.

Not really, because the dual camera of the mobile phone actually plays a role when we take pictures, we just don't know it.

This depends on different mobile phones, some Android mobile phone manufacturers will use a number of lenses in order to promote good sounds, but the two cameras of Apple mobile phones are easier to use.
