The Huawei Mate 9 may have two cameras, but its implementation is arguably the best of the bunch.Dual camera setups on smartphones are growing in popularity, not only with device makers, but with users as well. Each manufacturer tries to set itself apart from one another. The likes of Apple, OnePlus, Motorola, Huawei, and more recently, Samsung, have all released devices with two camera modules.
Apple’s Portrait Mode uses both lenses to add depth to a photo, resulting in a blurry background commonly referred to as a bokeh. The OnePlus 5 has a similar feature, with a similar camera setup.
With the Note 8, Samsung is quick to boast about both cameras being equipped with optical image stabilization, or OIS. Typically, only the wide angle camera on most devices has OIS, while the secondary — most commonly a telephoto lens — lacks the feature.
A telephoto lens lends itself to a true 2x zoom, before digital zoom takes over and often wreaks havoc on your photos.
Then there’s Motorola and Huawei, who use a traditional camera, and a second monochrome camera. That is, a camera dedicated to only capturing photos in black and white. I know what you are probably thinking — Wait, what? There are at least a million filters and editing apps, each one doing a fine job of faking the monochrome look.
Indeed, there are, and purists will celebrate the ability to capture true black and white photos, similar to how our ancestors captured memories years ago.
But it turns out, there’s a legitimate advantage to a monochrome camera on a smartphone: A monochrome camera captures more light, which leads to sharper, more realistic photos.
For devices such as Motorola’s Moto Z2 Force, which has two 12-megapixel sensors, one color one monochrome, the second lens is used for depth effects or for black and white
