There are certainly many benefits when owning a smartphone with dual cameras and most Android manufacturers have seen it. Take a look and you will see why this is becoming the newest trend.

Dual cameras: the benefits

The most noticeable benefit is the focus, which can be seen from images taken by Huawei P9. The two cameras, along with laser autofocus mechanism increase the focus speed. Having dual cameras helps the phone to get a sharper focus on objects, resulting in highly detailed photographs. When a photo is taken, both cameras take simultaneous images, one in color and the other in black-and-white. After that, the software will stitch these images together, creating a brighter and higher quality image.

The second benefit is bokeh, an effect of blurring the background to help viewers focus more on the subject. This effect can be achieved by using wide aperture or a zoom lens or a large sensor. But most cameras on smartphones have a fixed aperture and small sensor, so taking a bokeh portrait is not an easy task and has to rely more on software. But dual cameras have solved this problem by giving you more control over the hardware.

The last benefit of is zoom and perspective. A zoom lens can easily change the focal length while prime lens can not. However, a zoom lens is more expensive and not very compact, so putting that on a phone will create a bulky device like Samsung K Zoom. But thanks to dual cameras, you can now freely switch between the two focal lengths. There are some other features you can play with too, but you can easily find them out yourself.

Dual cameras: conclusion

Thanks to technology innovation, we might even see cheaper phones with dual cameras in the near future. And having a phone like that is a plus for any person even if you are not into photography.
