Most users and fans believe that size comparison is mainly what sets the iPhone 7 and the iPhone 7 Plus apart. Looking closely, the camera is one element that differentiates Apple's newest devices.

To many, nothing much is known about the second optical feature of the 7 Plus. This unit has a couple of 12 megapixel camera which integrates to produce a high quality image. Both photo trackers have contrasting lenses. One is fitted with a 28mm f1.8 wide angle optic. The other has a 56mm f2.8 lens identified as telephoto which zooms in on a subject without sacrificing quality the way digital zoom usually does.

Apple is taking a different approach with its dual camera. The combination intends to straighten the greater details of a subject from afar and settle the depth data between the two lenses through software.

The 56mm-frame is actually the second camera. To the uninitiated, a level of difficulty is initially associated in activating the higher optic lens. After opening the camera mode, users need to tap the circle icon on top of the shutter button that indicates 1x. Touching it will change the detail to 2x which means that the second camera is on.

The viewfinder must be used in order to zoom above 2x range. Another option is to slide up and down or left to right the point over the 1x logo. However, zooming past 2x will have a negative impact on image quality. At this point, the camera is just cropping the image in real time rather than getting a close catch at a subject.

Going overboard with regards to the zoom limit of the second camera also indicates blowing up the pixels which is why the first optic lens is there to provide a significant balance in coming up with a quality image. Photo editing applications are in place to address this type of situation.

Initially, an image is captured by saving it as an unfiltered sensor data on iOS devices. Then enhancement sets in. At the moment, Apple and third party developers are experimenting on computational photography to produce synthesized pictures or videos. This beta phase will likely be integrated in the next iOS 10 update.
