The 7 best dual camera smartphones
What, then, is this so desired trait for? The goal is to achieve the bokeh effect in portraits and in general photographs without worrying about technical definitions and framing rules and depth of field.It is a fact that dual camera technology in smartphones has achieved this in a simplified way and it is necessary only touch the screen to focus and touch the shutter to "shoot."Better at heights than in others, the results appear and social networks rejoice with so many photographs that leave already envy the most applied mid-range digital cameras.Some of the pioneering smartphones in this "art" were the P9 and P10 ranges from Huawei, followed by partners by the Mate 9 and Mate 10 brothers. But just to mention one of the brands that helped spark this trend, apply this technology to the mobile terminals, since many other manufacturers already do it with mastery.

Huawei Mate Pro 10

Samsung Galaxy Note 8


iPHONE X



Asus Zenfone 4 Pro


OnePlus 5T


Honor View 10



LG V30 H930

Undoubtedly, all of them followed the "obligation" to offer this possibility to consumers, from the much-desired iPhone to models such as the new Asus Zenfone 4, Sony Xperia XZ, LG from G to V, Samsung from lines 8 , to which are added many other examples in the mid range.
And the list will certainly increase in the coming days, even because the Mobile World Congress is almost starting and anticipate many leaks of the smartphones of the leading brands.

Smart TechnologyIn general, and without great technical overtones, let's see what a dual chamber system can do: they are two distinct lenses that complement each other or, if you prefer, two independent sensors that work as a team.In most cases, and more in terms of photography and less in video, the main sensor records images with a normal information base, namely sharpness, contrast and illumination. Then the other sensor adds detail and some additional information, so to speak, as is example the "game" that is done with the depth of field.On the other hand, as well as being able to do effective optical zoom, there is another type of possible action, a little like Huawei: a lens captures monochromatic images, richer in brightness and detail, so that the other lens " of color images - the combination of both registers is favored in terms of capture in poorly lit environments, for example.

That said, think about how other technologies associated with smartphone cameras combine with dual-sensor systems and how the results are getting better as we gain access to increasingly advanced, though expensive, smartphones.
We are talking about image stabilization systems to shoot and film, optical zoom, immensely fast automatic modes to determine each scene, effective flashes, accurate focus and even double front cameras that film in 4K ...
It's the future of smartphone cameras that has already arrived, so it's time to go through the gallery above and choose your top-of-the-range dual camera, without forgetting that in the next few days this list may suffer (major) changes.
