Why is the photo of Apple's mobile phone blurred?

Question 1: How does iphone and Apple capture the background blur effect of 1? Open the camera app on the iPhone. I don't know if devices below iPhone 3GS can be used, but devices above iPhone 4 can. 2. Put the iPhone 7 ~ 20cm in front of the background to be blurred, press the release screen, and then you will see the words AE/AF Lock at the bottom of the screen (if you have no idea about the distance of 7- 10cm,

3. Place the iPhone 7 ~ 20cm in front of the real target to be photographed. At this time, you will see that the target is particularly clear on the screen, and the background that needs to be blurred has been blurred.

4. Keep the iPhone stable, press the volume button or the photo button on the screen to take a photo, and you have already taken a photo with a blurred background.

Question 2: How to shoot the background blur effect with iphone6s? When shooting, focus the object you want to focus on the screen. The photos taken in this way will have a certain depth of field. You said the background is empty. There is also retouching with software. Many softwares have such filters or effects.

Question 3: What happened to the sudden blurring of Apple's mobile phone camera? It is still unclear that the sense of closeness is blurred because the focus of the lens is far away, not close. Generally speaking, where is the key point, then that place is the clearest.

But sometimes both sides of a photo are clear, because both sides are within the depth of field. (depth of field: the lens is at a certain distance from the scene, and the picture is clear within a certain range of this distance, which is called depth of field. The range of depth of field can be changed. The deeper the depth of field, the more clear places, the shallower the depth of field, and the more blurred places. The factors that affect the depth of field are lens focal length, lens focal length and aperture diameter. Shallow depth of field is often used to create blur effect in photography, and many photographers like to play with it. )

Question 5: How does Apple 7plus take photos with blurred background? The background blur of 100 is a great photographic effect. By blurring the background, the viewer can focus on the key points of the photo. But at present, it seems that only high-end cameras such as SLR or micro-single can sell the effect of background blur, but in fact, the iPhone in our hands can sometimes do it. Today, it is very simple to talk about how to shoot the effect of background blur with iPhone. 1. Open the camera application on the iPhone. I don't know if the equipment below 3GS is ok, but the equipment above 4GS is ok. 2. Put the iPhone 7-20cm in front of the background to be blurred, and press and hold the screen before releasing it. At this time, you will see the words AE/AF lock appear at the bottom of the screen (if you have no idea about the distance of 7- 10cm, it is about the length of half a palm. ) 3. Put the iPhone 7~20 cm in front of the real target to be shot, and then you will see that the target is particularly clear on the screen, and the background that needs to be blurred has been blurred. 4. Keep the iPhone stable, press the volume+button or photo button on the screen to take a photo, and you have already taken a photo with a blurred background.

Question: How can iphone and Apple shoot the background blur effect and adjust the focus, or the later P picture can also be used.

Question 7: How to take photos with blurred background with iphone, and focus on the object you want to focus on when shooting.

The photos taken in this way will have a certain depth of field.

You said the background is empty.

There is also retouching with software. Many softwares have such filters or effects.

Question iphone background blur How to shoot iPhone7 Plus background blur? First of all, this "portrait" background blur is only applicable to iPhone7 Plus dual-camera smartphones, and non-dual-camera phones with iPhone7 and below do not support this function. In addition, the system must be upgraded to iOS 10. 1 or above. If these two conditions are met, the iPhone7 Plus portrait background can be blurred. Comparison between normal photos and blurred background proofs after iPhone7 Plus turns on portrait mode; After upgrading the version of iOS 10. 1, turn on the camera, switch to "portrait" mode in the bottom photography mode, and then take pictures to realize the background blur effect, as shown below. After taking pictures in "portrait" mode, the proof effect has a blurred background effect, which brings an experience similar to that of a SLR camera, which is still very good. Let's take a sample portrait with blurred background. IPhone7 Plus background blur shooting sample article Finally, talk about the experience of virtual photography of iPhone7 Plus. Interested friends may wish to know about it. In fact, many flagship phones of mainstream manufacturers are equipped with dual cameras, and there are not a few "long and short focal lengths" with different focal lengths like Apple, but the question is why iPhone7 Plus can take photos with different effects. According to the physical characteristics of the iPhone7 Plus, the equivalent focal length of the telephoto lens of the iPhone 7 Plus is 56mm, and the aperture used is f2.8 Compared with the wide-angle end of 28mm, this lens has certain background blur ability. Although the aperture of F2.8 is not as large as that of f 1.8 of that wide-angle lens, it is definitely a large aperture level if it is placed in a SLR lens. Therefore, even if the "portrait" function is not turned on, a better background blur effect can be achieved. However, when shooting, you need to manually zoom to 2X and deliberately separate the foreground from the background to get a photo with blurred background, which means that you need a little shooting skill. This upgrade of portrait function makes all this more "stupid". As long as you enter this mode, the 2X telephoto mode will automatically turn on. If your distance is not ideal, the phone will also prompt you to "move away" or "put the subject within 2.5 meters". In terms of user experience, Apple has always been good at it. I carefully analyzed the photos taken in portrait mode. Needless to say, the main characters are angular. If the processing method is similar to Gaussian blur, the edge will also be "eaten", and Apple's algorithm is "accurate edge matting" by applying PS terminology. The most pleasing thing is the blur of the background. It's not so vague that I can't see anything clearly, but so soft that I think it can set off the main body and the atmosphere well. For a photo taken by a mobile phone, it is difficult to achieve this effect simply by relying on the quality of the lens, so this is also the powerful place of Apple ISP algorithm. In the same scene, you can compare SLR with iPhone 7 Plus. If the lens quality of the SLR is slightly better and the focal length is longer, you can take a blurred picture of the background, but you need to control the aperture of the SLR not to be too small and ensure the focus of the subject is clear, so as to get an ideal blurred picture of Jiao Wai, which means that the "portrait" function of the iPhone 7 Plus has reached the level of "quasi-SLR". Why do you say "quasi-SLR" level? Because for some users, the effect of defocus blur has reached a harsh level, they are pursuing "defocus bilinear", and it is extremely difficult to simulate with the algorithm. Back to the ISP algorithm of iPhone 7 Plus, in fact, when switching between 1X and 2X before, it showed the ability of its algorithm. Under the action of the algorithm, you can't feel the two lenses cooperating. When you drag the zoom ring, it is like the operation of a lens. The chromatic aberration and resolution of the two lenses are almost the same, so you can't see that they were shot by two different lenses. & gt

Question 9: How to take a blurred background photo with an Apple phone? There is software to bring. After the iPhone7Plus updates the ios 10. 1 system, there is a portrait mode in the camera, so you can shoot.

Question10: How to blur the background of iPhone 7 photos In Apple's latest iOS 10. 1 system, the biggest point of view is to add the "portrait" mode, which can realize the blurring effect of the background of people's photos. Recently, however, many iPhone 7 users reported that they couldn't find the "portrait mode" and didn't know how to use it. Let me answer the question below. Q: Where is the portrait mode of iphone 7? A: Because the "portrait" mode is mainly customized for the dual-camera mobile phone of the iPhone 7 Plus, the rear of the iPhone 7 is a single camera, which does not support fuzzy photography of the "portrait" background. Therefore, even if iOS 10. 1 is upgraded, the "portrait" mode cannot be found in the camera interface, mainly because the mobile phone does not support it. Comparison of normal photos and background blurred proofs after iPhone7 Plus is turned on in portrait mode. Does iPhone 7 have the function of background blurred photos? A: In theory, iPhone7 does not support the function of blurring portrait background, but users can install some camera software, and with the help of some internal background blurring filters, they can also experience some camera functions with blurred background. The camera that comes with iPhone7 doesn't have "portrait mode". For example, if you install the "Meitu Xiu Xiu" camera software in iPhone 7, which has a background blur filter, you can also experience a portrait background blur photo effect similar to iPhone7 Plus, but the experience is not as perfect as Apple's native one, almost 60% to 70%.
