In the pursuit of technology!
Perhaps when You read this review, then the mass will be a mobile device equipped with 4, 5 modules for taking pictures. Some Chinese brands have long been promising the machines with 6 “eyes” on the rear panel. But as practice shows, cheap gadgets use this step is purely for marketing purposes, and make a horrible photo — even worse than on my old iPhone 5S with one camera.
So this question is not important the quantity but the quality.
I’m not going to delve into history and tell me who first introduced similar technical capabilities and carried out a revolution in the market of mobile devices. Don’t want to praise the producers (or Vice versa — to criticize). But at this stage, the leadership holds the Galaxy S9+, P 20 Huawei Pro, iPhone XS Max. Read the comparative tests at DXOmark. The situation is constantly changing, so it is better to track the relevance of information, looking at the actual sources. Two cameras on the phone what is needed?
The vast majority of smartphones don’t have optical approximation (zoom), which is so much lacking in many owners of gadgets. Digital zoom — no problem, but the pictures are not too clear, but in low light all tin. Until recently, manufacturers equip the device with a single module with a wide angle lens that is not very well photographed faces (violation of the right geometry) and distant objects. That’s like looking at a big moon, I want to capture the moment, but when we obtain a smartphone, the effect is unsatisfactory. Instead of a large, glowing disk — small dot in the dark.
In order to rectify the situation and earn more money, the mobile giants have decided to place the two rear camera (and now three). But what does this mean? Because the dimensions (thickness) of the phone do not allow to establish inside complex optical mechanisms.
It turned out, if each of the solar cells will have a different focal length, for example, 24 and 55 mm, then using the built-in software easily you can perform the approximation by switching from one camera to the second.
The result is a zoom without loss of quality: But that’s not all! Dual camera smartphone benefits of bokeh
Professional cameras are familiar with this concept. Many of You have also seen portraits where the person is clear and the background blurred, soft. So, the use of dual lenses gives you the opportunity to implement a similar effect in the phone. You can shooting settings to enable/disable it at Your discretion. By the way, after patch 10 MIUI on Xiaomi appeared similar function in portrait mode (not only for the rear but for the front camera). What trick works even on the old device with one “eye”.

For anybody not a secret that in low light the images are grainy, with unrealistic colors. The light passes through the lens and hits the sensor. So, you need to increase the capacity, but the dimensions of the module should not become stronger. So why not use 2, 3, 4 “the window”? After all, through them to the matrix will get more brightness. In the end, simultaneously utilizing multiple lenses, you can get the image without noise even in the evening hours.
I think the point is clear.
Oh and don’t forget about artificial intelligence, which is currently being implemented everywhere. It helps the device to learn, memorize, analyze and with every subsequent photo better than the result obtained through the use of individual processing algorithms are the optimal settings for shooting in automatic mode.
Dual camera smartphone why — we understand that gives. If you still think there is no need to overpay for a marketing ploy, then look at online comparison of images taken on a cool camera phone from the past, and modern phones with 2-3 optical components.
