What Is The Iphone Dual Camera

The dual iPhone 7 Plus camera explained

For a long time, Apple'south 8MP camera was the option of the bunch for those looking for the best image quality in a smartphone. Heck, Apple even rammed information technology downward our throats with smug billboard posters preaching the line 'shot on iPhone'.

Matter is, the competition defenseless up, and for the last couple of years Apple tree has seen the crown of all-time photographic camera in a smartphone slip from its grasp.

Apple determinedly stuck with the 8MP camera all the style up to the iPhone vi and half-dozen Plus subsequently nosotros beginning saw it in the iPhone 4, only Samsung fought back with the likes of the Galaxy S6 and Milky way Edge S7 Edge, jumping ahead of the mighty iPhone (when it comes to image quality at to the lowest degree).

Even the bump to 12MP on the iPhone 6S and 6S Plus failed to see the Cupertino firm fully close the gap with its South Korean rival.

Plenty of other manufacturers have tried dual-lens technology on their phones already with the HTC One M8, LG G5 and Honor 6 Plus all feature double snaps, while Huawei took a more extreme, imaginative route with their dual lens P9 Plus.

The clever bit though is what's happening inside, with the P9 sporting two sensors - one capturing colour data and the other black and white data. This information is cleverly combined to produce an image that has meliorate depression low-cal functioning (reducing the fuzzy grain-like effect that can plague smartphones when light levels drib), likewise as improving overall image quality.

This approach neatly sidesteps the fact that the sensors in smartphones are tiny...even a run of the manufactory compact photographic camera sports a larger sensor, with larger photosites (pixels to you and me) that accept amend light gathering capabilities, resulting in ameliorate noise control and sharper paradigm.

With the quest for ever more slim and compact devices, squeezing in a larger sensor into a smartphone isn't a realist suggestion, so this arroyo past Huawei is a clever one.

The fightback

Merely Apple is fighting back with the iPhone 7 Plus, with a duo of all-new backside illuminated 12MP cameras. However, rather than opting for Huawei's approach to the problem, Apple has taken a different route.

Realising that the stock-still wide-bending lens is not suited to all types of photography (and despite by marketing propaganda, a digital zoom is a rubbish compromise), Apple tree has opted to just stick a secondary telephoto lens (with an discontinuity of f/2.8) on the back with another 12MP sensor aslope the wide-angle lens (this time with an discontinuity of f/1.8).

Apple aren't giving much away with specific focal lengths at the moment, but the lens on the iPhone 6S was well-nigh the equivalent of 28mm.

What promises to be interesting to come across in apply is the manner that these two lenses work in tandem, combining to deliver a 2x optical zoom.

Not only that that, but both cameras can be used together to achieve shallow depth-of-field mode images (according to Apple at least) that are easily achieved with a DSLR, but well-nigh incommunicable to do with a smartphone. We'll be looking forrard to trying this out ourselves.

It's dainty to meet paradigm stabilisation, though the specs are a piddling vague on how constructive this is, while it'south also fantastic to see raw file support finally brand information technology to the iPhone, as well.

The iPhone 7 Plus photographic camera certainly looks like information technology'll shake things upwardly, just this dual lens approach is nothing new in the world of photography - Kodak even dabbled with it dorsum in 2006 with the horrible EasyShare V705 digital camera, while the zoom technology has also been seen before with Nokia'southward PureView technology.

And then it may be goose egg new, but if Apple has got the technology right, information technology could see the iPhone 7 Plus ascent to the top of the smartphone camera tabular array.
