iPhone 7 Camera Upgrade: Why we need the Dual Lens

By Mar 09,2017 22:18 pm

An invitation has been sent out to the journalists to attend a San Francisco event which is rumoured to announce the launch of iPhone 7. The invite comes covered with a multicoloured bokeh probably suggesting the exciting camera upgrades which would come with the new model. Since a long time it has been rumoured that the dual lens is going to be one of the striking features of the iPhone 7 Plus. Moreover the numerous leaked images suggest the purported inclusion of twin cameras. The second camera module of the iPhone7 (or at least on the 7 plus model) is going to help the photography enthusiasts immensely. After all the iPhone competitors have caught on by now. For instance the G5 by LG features an ultra wide angle lens, HTC has surprised everyone with their One M8 depth sensing camera and the all new P9 by Huawei comes with a special camera just for black and white pictures. It was high time Apple introduced a stunning camera feature to keep up with the competition.

The popularity of iPhone coupled with the considerable influence of Apple is expected to influence other manufacturers to come up with dual lens camera phones. The inclusion of extra cameras is proving to be quite economical for the manufacturer in one hand and extremely useful for the consumers on the other. In the future you can possibly witness phones with numerous sensors and lenses as hinted by the Light L16 Camera. However for the time being it appears that dual cameras are going to dominate the market trend inspiring more people to explore the new realms of mobile photography. When the speed limit of single processor cores were exhausted, they compensated by multiplying the number of processors. There is no reason why this neat strategy wouldn’t apply to smartphone cameras as well.

Why Dual Lens

The disadvantages of an actual smartphone camera:

Though clicking photos with your smartphone is a matter of simplicity and convenience yet you have to admit that the quality of picture is never great. The real problem comes when you want to zoom in with the phone cameras. Your phone is not actually ‘zooming’ in the telephoto lens sense of the term since the smartphone cameras come with just a digital zoom. When you zoom in on a subject all it does it enlarge the pixels from the middle of the frame. You must have already noticed that when you zoom in your smartphones the resulting pictures are grainy and of very poor quality.

Benefits of having a dual lens on iPhone 7

The advantages of having a dual lens on your iPhone are numerous:

Firstly, dual lens will result in a more effective zoom which would give you a better quality image with crisp detailing. It would allow to double the sensor size without enlarging the size of the phone. The second camera would strengthen photography in numerous ways apart from a second focal length. For example Huawei has kept the resolution and focal length of both its Leica cameras intact though one of them is only for monochrome.

It goes without saying that the camera phones of this generation are capable of taking excellent shots especially during the day time. However they still cannot imitate the shallow depth of field offered by the large sensors of the DSLRs. The depth of field is regarded as an unique physical constraint which makes it impossible to come up with a sensor and lens combo offering substantial depth of field within the limited size of a smartphone. You can be rest assured that the best cameras are cumbersome for a reason. However the inclusion of another lens would allow the photographer to measure the depth info so that they can use it to replicate the realistic DoF during post processing. It would also allow the user to adjust the DoF according to their liking. This has already been tried without much success by One M8 and HTC. The depth of field effect in the Google cameras is also quite slow and haphazard. Huawei has come up with a whole new approach which is in need of fast implementation. All we can do is sit and wait till we find out how the dual lens of the upcoming iPhone model helps.

The iPhone 7 plus is expected to take smartphone photography to a whole new level. A professional photographer can make many a great images out of a single camera in their iPhone but even the best photographers are going to be at a loss in low light conditions and certain other scenarios. The addition of a second camera in the iPhone 7 plus is sure to enhance the picture quality of the first. It is expected to offer a whole new perspective or provide much more depth of field options. The amateur photographers can now have a lot more flexibility while creating their photos. The iPhone 7 plus camera is expected to offer stunning performance in low light conditions giving you 4x the resolution of an ordinary smartphone camera.

Conclusion

These days a new term has been introduced in the field of photography, viz iphonography. So if you are a photography enthusiast who loves to take shots on the move you should definitely think about upgrading to iPhone 7.
