Portrait Mode is a new photo format that was added to the iOS Camera app as part of the iOS 10.1 update. It is currently available for the iPhone 7 Plus only, because it depends on the twin-lens camera setup that is unique to that device.
Portrait Mode uses the iPhone 7 Plus's twin-lens rear camera setup to create a much sought-after artistic depth effect, whereby the subject is in focus and the background is blurred. In photographic circles this effect is known as bokeh, and when done right it can look fantastic.
In this article we explain how to use Portrait Mode on the iPhone 7 Plus, and offer a few tips that will help you take better shots using this feature.
How to take Portrait Mode shots
Portrait Mode is accessed, like Photo, Video, Slo-Mo and the rest, via the rotating swipe menu at the bottom of the Camera app interface. (The full list of formats if you're using an iPhone 7 Plus is now Time-Lapse, Slo-Mo, Video, Photo [default], Portrait, Square, Pano.)
Remember that Portrait Mode is only available if you've got a) an iPhone 7 Plus and b) iOS 10.1 or later, so if the option isn't there then you need to either update your software or upgrade your phone.
Open the Camera app (remember you can just swipe in from the righthand edge of the Lock screen, or swipe up from the bottom of the Home screen and tap the camera icon in Control Centre), and swipe left one step in the rotating menu so that PORTRAIT is highlighted in yellow.
The app itself will offer a few tips on lighting, composition, position etc, but you just need to tap the shutter button to take your portrait shot.
Most of the usual options and settings aren't available in Portrait Mode, incidentally, but there is a timer: tap the clock icon at the top and tap either 3s or 10s, depending on whether you want to set a three- or ten-second timer.
Portrait Mode is at heart an artistic effect, so we should probably be saying that there are no rules, experiment and be creative etc. But there are some rules, really.
You need the subject of the photo to be fairly close - the feature itself recommends 2.5 metres or less. The background, by contrast, needs to be significantly further away: the larger the gap between subject and background, the more pronounced the depth effect will be. If your subject is standing against a wall there will almost no effect at all.
Lighting is important, too. We found the effect underwhelming in artificial light indoors; in early morning sunlight the results were rather lovely.

(Portrait Mode itself will remind you of these basic principles if it sense that the subject is too far away or there isn't enough light, although rest assured that you can happily ignore its advice and shoot anyway.)
As with other iPhone photos, you can change the point of focus: tap the object on screen.
Be aware of small items in the shot that may confuse or disrupt the depth effect. In this comprehensive test of the feature by Brian LW Moore, two ropes hanging across the front of a picture of a monkey caused the feature all kinds of confusion: it sensed that the thinner one was a foreground object so tried to place it in focus, but lost it in the background either side of the subject; and the thicker rope has a horrible error above it. (Here is the photo in question.)
In other words, simple compositions are generally best. Try to avoid stray bits and bobs that are liable to confuse the effect, particularly ones in front of the subject - or at least be aware that they may cause a few shots to come out as duds. Even loose strands of hair can confuse the feature, although it probably won't be noticeable.
Tips from the professionals
Those are the tips we've found from our experiences with Portrait Mode, but we're willing to concede that there are people out there who know even more about the subject than we do. We're talking about the professionals.
Happily, in a 6 December Newsroom article, Apple has collected a range of tips on using Portrait Mode from professional photographers that have tried out the feature. Here are some of the highlights.
Jeremy Cowart suggests you "cut out the distractions from your subject" and "try to find the shade and put the sun behind your subject as a nice back light." He adds that "pulling the exposure down just a hair really makes my images look more cinematic."
JerSean Golatt recommends that you "get up close to your subject to bring out the details".
Pei Ketron talked to Apple about the best ways of photographing animals with Portrait Mode. "Give your pup some space," she advises. "Portrait mode uses the telephoto lens, so a distance of about eight feet away is recommended. Have treats ready. You'll get the best results when your subject isn't moving."

Finally, Benj Haisch spoke about the best conditions for Portrait Mode photography. "Having soft, diffused lighting will help with keeping the photo flattering to your subject," he explains. "Find a space that isn't too busy or distracting, as Portrait mode will create a photo that really pops."

How to view and manage your Portrait Mode photos
By default, iOS 10.1 stores two versions of each photo you take in Portrait Mode: one with the depth effect applied, and one with conventional effects. This means that when you're looking through Photos (in the Photos section of the app - the lefthand icon in the bar at the bottom) you will see twice as many photos as you took.
You should be able to tell the photos apart, based on whether they have a blurry background or not. But if not, tap the photo in question so that the white borders appear at the top and bottom and you get all the interface 'furniture': the share, like, edit and delete icons at the bottom, and the date and time it was taken at the top. If it's a photo taken with the Depth effect applied, you'll see a label telling you as much at the top lefthand corner of the image.
By the way, you don't have to put up with those duplicate images clogging up your photo library. If you'd rather iOS just kept the Portrait Mode shot when you're using Portrait Mode, open Settings, then scroll down to the sixth bank of options and tap Photos & Camera. Scroll down again and find the section headed Portrait Mode. Where it says Keep Normal Photo, tap the green slider so it turns white. (If running out of space is a problem for you generally, try our article How to make space on an iPhone.)
It's also possible to just view photos in your library with the depth effect applied. Open the Photos app and go to the Albums section (the righthand icon in the bar at the bottom). Scroll down a bit and you'll see an album called Depth Effect.
