The Huawei P9 is a cihneses company product which have dual camera. Oh. You might be wounder why it is using dual camera?
Both the cameras are same in looks but they have different in functions. The right side camera shoots RGB( Red, Green and Blue) to produce a color image, and left side camera takes care of the monochorom image ( images with one color but different in shade i.e., black or white) . Huawei’s clever software puts the two together to create a single, high-quality image. Huawei says the monochrome lens brings out the detail, and lets in 200 percent more light than the RGB lens, which takes care of the color.
Huawei saying that they used Leica camera. The Leica cameras are high quality and very good camera which have gained renown from their use as the camera of choice for several famous street photographers. So I think if you buy this phone, you dont need DSLR.
