The big novelty in the smartphone world in recent months is the dual rear camera, which guarantees better photo quality
We’ve all seen them, some of us even have a smartphone with this technology. We are talking about dual rear cameras in phones. This is no longer a novelty, but it is still not clear what they are for. So let’s take a look at what a dual camera is for.
Of the two cameras, one is the main camera, which is crucial for the quality and beauty of the photos, and the other is the secondary camera that helps the main camera in certain situations and allows you to use additional functions. The use of an additional camera aims to obtain images with greater depth of field, greater clarity and an overall faster focusing ability. The functions of the secondary camera vary depending on the smartphone model. In the LG G6 we find a wide-angle lens, in the iPhone 7 Plus a telephoto lens, and in other cases an ordinary black and white lens.
Use of dual cameras
At this point the question is legitimate: what is the point of having a black and white camera? The task of the black and white lens is to capture, quite intuitively, only black and white scenes. It helps to adjust the amount of light reaching the point of focus, resulting in a sharp image with lots of detail. In other cases, the dual camera is used to emphasize one object or figure above others. You can also use this function after taking a photo.
Huawei P10
Let’s take a look at the most popular dual cameras on the market. Let’s start with the one that’s in the Huawei P10. It is a monochrome camera that helps to get the best of both shots to present the user with the most perfect final shot possible. This feature is especially useful in suboptimal lighting conditions, but also in excessive brightness.
iPhone 7 Plus
Apple has done a different job, the two cameras are performing different tasks from each other and also have different functions. The main sensor is a 28mm wide-angle lens, while the other is a 56mm telephoto lens. The latter is perfect for portrait shots, that is, shots that emphasize the character or subject in relation to the scene, lending a natural accent to depth of field and detail, even the tiniest of details.
LG G6
On the LG G6, the dual cameras use the wide-angle effect, which is useful for taking pictures in a panoramic style without losing naturalness or changing the actual size of objects and landscapes. This is the largest field of view currently available for a smartphone camera.
Conclusions
In conclusion, after this quick overview, there are two questions: is a dual camera better than a single one, and which one should you buy? The truth is that the quality of your photos depends entirely or almost entirely on the main camera. So a good rear camera can’t be punctured by a decent dual camera. The advantage of a dual camera is that it allows you to take pictures with very special effects.
