Apple’s Portrait Mode on the iPhone 7 Plus is the Camera’s Best Feature

With the iPhone 7, Apple is taking mobile photography to the next level. The 4.7-inch iPhone 7 received some nice camera upgrades, however the 5.5-inch iPhone 7 Plus is truly a mobile photographers dream.

The iPhone 7 Plus is packed with two 12-megapixel sensors, one a wide angle lens and the other a telephoto lens. Apple’s dual camera system is capable of taking absolutely stunning photos with brilliant color accuracy and crisp detail.

With the iPhone 7 Plus sporting two camera sensors, Apple’s flagship iPhone is capable of all sorts of photography tricks, including a new “Portrait” mode. The feature blurs the background of a photo and causes the main subject in the photo to really stand out.

Apple is able to achieve this because its dual camera system is capable of measuring varying degrees of depth within a photo. As a result, Apple’s software does its magic and applies an artificial blur to the background while bringing the subject into sharper focus.

Blog prolost has called the Portrait mode feature “legit.” All of the effects are achieved by applying techniques from computational photography.

“I’m pretty sure that with only two cameras, you can’t build a useful light field. But can you do computational photography? That’s a trick question, as the iPhone, and many other mobile phone cameras, are already doing computational photography. Already the iPhone will automatically perform an HDR merge of two exposures, for example. But even when the iPhone snaps a single, non-HDR exposure, the amount of post-processing it does is considerable.”

The feature is available in the new iOS 10.1 beta for anyone interested in checking it out. Here is what the blog says about the feature:

“Apple calls their initial two-lens computational photo offering Portrait Mode, and the most recent developer beta of iOS 10.1 includes a beta version of it. Under the right circumstances, this mode enables a so-called “Depth Effect,” where both cameras fire simultaneously, and a depth map is built based on the subtle stereo disparity between the captured images. This nine-level depth map is used to drive a variable-radius blur. The result is a photo with simulated shallow depth of field.

This process can never be perfect, but can it be good enough?

Oh hell yes it can.”
