How dual camera will help iPhone 9 with the best pictures


Instead of a single camera in the iPhone 9 Plus installed two cameras simultaneously. This is a wide-angle 28mm lens aperture F / 1,8 1/3 “sensor and a lens with a focal length of 56 mm and aperture of F / 2,8 to even smaller 1/3.6” sensor. A combination of the two chambers is implemented 2 x optical zoom. in the near update iOS add background blur function to the type of professional. The largest (1 / 2.3 “) sensor in its class at the Samsung the Galaxy the S7, and then iPhone will not be able to oppose even his incredible 100 billion each processing operations Images.

The iPhone 9 Plus there is no optical stabilization. If the light is sufficient, and all is well, your smartphone uses the module “portrait” 56-mm camera and we get a little more detail. Depending on the lighting and the selected zoom, the device determines whether a photo shoot two lenses simultaneously, only to shoot wide-angle or only the “portrait” lens. In fact, the phone automatically change the lenses out of the bag – just enter professional photographers to achieve a better result. But shooting at a lens with a larger focal length requires a fast shutter speed to prevent blurred images. However, the darker the lens aperture of F2,8 with and without stabilization blur from shaky hands is even more. Therefore, in some cases, increasing the recorded image, you will find a trick Apple – it will be removed at the wide-angle lens and “swapped” 2 x digital zoom. This also fall into a situation where the “portrait” lens cannot focus because of the close shooting distance or at shutter speeds slower than 1/60 second. All this illustrates a problem that will face all smart phones, developed in the last few years on steroids software image processing, aberration correction and others. A software revolution has found itself in a hardware limitation in this case – the physics and optics. A revolution is needed there now. This platform with two lenses – apparently only the first step in the iPhone. C were such decisions and the company Litero Light. On the basis of this platform, we will see many other interesting applications of “computing” photos, especially if given the green light to developers.
