The iPhone 7 Plus uses two cameras to zoom in closer on a subject without losing image quality. The iPhone 7 Plus uses two rear cameras to allow optical zoom without loss of image quality. The 7 Plus can also digitally create bokeh (background blur) with a feature called Portrait mode. The LG G6 also uses two cameras to optically zoom, but does so between a standard angle and a wide angle view -- the 7 Plus zooms between a standard angle and a tele lens. Huawei uses dual-cameras in a variety of ways depending on the phone. On its Honor 6X -- a budget phone nonetheless -- you change focus after you take a photo and there's a background blur mode similar to the iPhone 7 Plus' Portrait mode.
On Huawei's P10, there's a black-and-white camera which captures detail and lighting and a color camera that gathers color information, The P10 combines the two much like a coloring book resulting in pictures iphone 6/6s purple glow waterfall case with overall better image and color quality, And what about Samsung and Google? Currently neither company has a phone with dual-cameras, But, there are rumors that the upcoming Galaxy Note 8 will have dual-cameras, This is curious to me because Samsung had an amazing line of now-discontinued mirrorless cameras like the NX1 which was a CNET Editors' Choice, Bringing some of the NX1's image mojo to a dual-camera phone would be incredibly exciting..
But why stop at just two? Could there be a Galaxy S9 with triple rear cameras? Or an iPhone 11 with a quad camera system? If two cameras offer improved image quality and nifty features like focusing after the fact, what could a quad camera system offer?. For example, the iPhone 7 Plus has two cameras: one with a 28 mm lens and the other with a 56 mm lens. But if it had four cameras, there could be a 24 mm lens, a 28 mm lens, a 56 mm lens and a 70 mm lens. The result would be a phone with the coverage of an 24-70 mm zoom lens, one of the most common and versatile lenses sold. You would be able to zoom in (even more than the iPhone 7 Plus) for close portrait shots of friends and family or zoom out (as wide as the LG G6) to have a wide angle lens for tight spaces. All this without loss of image quality.
A side effect of multiple cameras could be a wider implementation of augmented reality (AR) on phones, too, The Lenovo Phab 2 Pro uses three rear cameras (one is an infrared camera) to run Google's Tango software, The idea that phone makers might add more rear cameras to phones iphone 6/6s purple glow waterfall case isn't that far-fetched, The company Light is releasing a phone-sized device called the L16 which has 16 13-megapixel cameras, The L16 isn't a phone even though it runs Android, The 16 cameras are made up of five 28 mm lenses, five 70 mm lenses, and six 150 mm lenses..
The smartphone-sized Light L16 camera is actually made up of 16 different cameras capable of 52-megapixel photos. For any given image, it takes a picture simultaneously with 10 of those cameras. The images from the 10 cameras are tiled and layered together with software to create a single high resolution, high detail, low noise picture -- up to 52-megapixels. While I don't think there will be a phone with 16 cameras anytime soon, the L16 shows that using multiple small cameras to create high-quality images is possible.
