Hands on with the i. Phone 7 Plus crazy new Portrait mode. One of the most talked about features of the i. Phone 7 at launch was the new Portrait mode. Its a software feature that uses the two lenses of the i. Phone 7 Plus to create the look and feel of an image shot with portrait settings on a camera with a telephoto lens. Simply put a pleasing blur that separates the foreground person from the background other junk. Arlington Asset Investment Corp.

Watch Beta Test Online Fandango GiftIm going to get a bit wonky in this piece because I feel the context will be sorely lacking once this feature hits widely and there are some that are interested. If youve ever had a portrait taken in a park or seen a wedding picture and wondered why they looked so much better than the images from your phone, the answer is really a three parter A relatively wide aperture is being used, which causes among other effects the field of focus, or the bit of the picture that is sharp, to be very narrow. This means face in focus, background not in focus. It was likely, but not always, shot with a telephoto lens. This enhances that separation between subject and background because tele elements in a lens cause telephoto compression, thinning out the apparent field of focus and putting faces into proper proportion. This is why a nose looks the right size in a proper portrait and looks too big with a wide angle lens. But mostly, the photographer took the time to learn how to use her equipment, positioned the subject appropriately and used her artistic judgment to provide a proper composition. Apple cant yet do anything about the last one for you. Thats your job. But it could tackle the first two, and thats what its done with Portrait mode.

It uses technology from Li. Nx, a company Apple acquired, to create data the image processor can use to craft a 3. D terrain map of its surroundings. This does not include the full capabilities of the Primesense chip Apple purchased back in 2. For now, were getting a whole host of other benefits from the two cameras, including Fusion, Apples method of taking image data from both the wide angle and telephoto lenses and mixing them together to get the best possible image. Were also getting Portrait mode, which launches today in developer beta and later this week in public beta. The Portrait mode, which prominently displays a beta notification on first launch, resides to the right of the standard photo mode in your camera app. There is no zooming, digital or otherwise, in Portrait mode.

If you want to get a feel for how this works, hold your hand up in front of your face and close one eye. Then open that one and close the other. Do you see how you can see around your hand Thats how Apples camera system is working. The wide angle and telephoto see slightly different angles on the image, allowing it to separate and slice the image into 9 different layers of distance away from the cameras lens. Once it has these nine slices, it can then pick and choose which layers are sharp and which get a gaussian blur blur effect applied to them. Update On additional inquiry, Apple clarified for me that it is in fact not gaussian effect but instead a custom disc blur. This is a blur with a more defined, circular shape than gaussian blur. So if youre one of the few that was hankering to know exactly what kind of blur was applied here, now you know.

Why the lag Well, for one this is a limited closed beta test, which is the perfect place to iron out issues like random, crippling lag. The test is meant to give. The preview blur effect is coming right from Apples Core Image API. Once the telephoto lens detects the subject, using autofocus and other stuff well talk about in a second, the image processor inside the i. Phone 7 will then apply blur in greater and greater amounts to the layers that are further away from that subject. So, for instance, if the camera analyzes the scene and pins your subject at 8 feet away, it will slice the image and apply a blur effect on a progressive gradient scale across the other layers. Things that are very close to your subject may be sharp included in that variable width slice of the in focus area. Once they get further away they get a little blur, then more, then more until things in the far foreground or far background are blurred to the maximum level. Again, the effect works to separate from both the foreground and background. You can shoot a subject in the middle of a scene and it will recognize that and separate accordingly. There is no precise scale to these distances because they are based on a curve that depends on how close you are to your subject, how much of the frame that subject takes up and how deep it is. In my testing, on average, once objects or scenery are out about 6 feet or more from the subject, youre at maximum blur. Inside that, youll see more or less blur applied to those slices. This all happens seamlessly and you see a real time preview of the effect on your screen, which runs at a fixed framerate under 3. FPS. My guess is 2. There is very little lag when shooting, around 6. If you see how long a full HDR shot takes to process, then youre somewhere faster than that and slower than a regular shot. In order to lock on to your portrait subject and to separate it as cleanly from the background as possible, Apple is using face detection to help it find the subject quickly and to tell the ISP what should be clear and what should not. On screen you will see a continuous coaching prompt which tells you whether there is enough light and whether you are too close or too far away for the Depth Effect to kick in. Portrait mode requires a lot of light to work and does not work well in low light or low contrast situations. It also requires that youre no closer than the 1. The mode sends both the standard image and the portraitized image to your camera roll, with a Depth Effect badge. The images it turns out are standard JPEG images that read as if they came off of the telephoto lens if you examine them. On the i. Phone, they are tagged with a Depth Effect badge. Otherwise they are identical to other images you shoot on i. Phone 7. So, why the telephoto First, this 5. Apples marketing, but it it closer to a normal lens in photographic terms.
