The new Huawei P9 has not just one, but two very special cameras, and for once they're both on the back of the phone.

Here's what you need to know about the Huawei P9's camera setup, including how to get the best out if its many features.

The two lenses may look the same, but they have very different functions. One shoots in RGB to produce a color image, while the other takes care of the monochrome images. 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 colors. Leica supplies the Summarit lenses, while Sony handles the 1.25-micron IMX286 sensors, resulting in a twin 12-megapixel setup with an f/2.2 aperture, regrettably, Huawei P9 Lite with a 13.0MP rear camera, no dual-camera.

The two lenses are accompanied by a hybrid flash unit, where a laser works out focal distances, or through contrast detection. It's all done automatically, and Huawei says it's the best system for multiple focus conditions, from close-up photography to complex scenes, and situations in challenging light.

By using the the two lenses together, you can create the popular bokeh effect — where parts of your photo are artistically blurred out — on your pictures, after you've taken them. Bokeh effects are usually only achieved using expensive cameras and special lenses, plus a considerable amount of talent. On the P9, taking the perfect shot requires only few button taps. Huawei Honor V8 will use the same dual camera of P9.

Understanding how the Huawei P9 Max, P9 Plus, P9 camera's features work is only the start. Get creative, learn a little more about the way Pro mode can alter pictures and what the settings mean, and you'll open up a world of potential.
