How does Apple's mobile phone take photos to blur the surrounding environment?

1. Find it on the phone's main screen and turn on the camera.

2. First of all, the distance from the background to be blurred is about the distance of a palm, and then it is ok if the phone can focus accurately, so the blur effect will be better.

3. At this time, we long press the screen and find that the focus frame flashes twice and then release our hand, and we will find a focus lock above the phone.

4. Just put the mobile phone in front of the subject and keep the distance as consistent as possible.

5. Click the screen when you want to cancel, and the yellow dialog box at the top of the phone screen will disappear.

Our mobile phone finds and opens the camera application on the main screen of the mobile phone.

1, we first need to blur a background about the palm distance. Of course, if the phone can still focus accurately, it will be better.

2. This is when we press the screen for a long time and find that the focus frame flashes twice and then release our hand, and we find that the focus lock will appear above the mobile phone.

At this time, we put the mobile phone in front of the subject and keep the distance as consistent as possible.

As long as we click on the screen when we want to cancel, it means that the yellow dialog box at the top of the mobile phone screen will disappear.

This is a photo in normal focus, and we can clearly see the blur effect. Because the shooting environment is dark, we can see a lot of noise.

IOS is a mobile operating system developed by Apple. Apple announced this system for the first time at Macworld conference on June 9, 2007. Originally designed for iPhone, it was later applied to iPod touch, iPad, Apple TV and other products. IOS, like apple's Mac OS X operating system, belongs to a commercial operating system similar to Unix. Originally this system was called iPhone OS. Because iPad, iPhone and iPod touch all use iPhone OS, it was announced at the 20 10WWDC conference that it was renamed as iOS(iOS is the registered trademark of Cisco's network equipment operating system in the United States, and Apple's renaming has been authorized by Cisco).

20 16, 1 year 10. In October, with the release of version 9.2. 1, Apple fixed a vulnerability that existed for three years. The vulnerability is that when an iPhone or iPad user accesses a network with a mandatory entrance in a hotel or airport, the login page will display the terms of use of the network through an unencrypted HTTP connection. After accepting the terms, users can surf the Internet normally, but the embedded browser will share unencrypted Cookie with Safari browser. With this shared resource, hackers can create their own false forced portal and associate it with the WiFi network, thus stealing any unencrypted Cookie saved on the device.
