How does iphone take long exposure photos?

Take long exposure photos. Now iOS 1 1 can use "Live Photo" (formerly called Live Photo).

Let me describe the operation mode in detail:

1. First, the system needs to be updated to iOS 1 1.

2. Your device needs these devices:

IPhone 6s, iPhone Plus, iPhone SE, iPhone 7, iPhone 7 Plus, iPhone 8, iPhone 8 Plus, iPhone X and other devices. Of course, you can also use iPad Pro and the latest iPad.

Then, you can do the following:

1, open the "live" photo interface;

2. Find an intersection with heavy traffic, or an overpass (you can also shoot a waterfall);

3. Press the shutter;

Note: Don't shake the phone for the first two seconds and the last two seconds after pressing the shutter (it is recommended to use a tripod or hold your hand on a fixed object, such as a railing). ), the principle of shooting live (dynamic photos) is that the camera will capture 1.5 seconds before and after the shutter, which is about 3 seconds in total, so it is very important to keep the picture stable.

4. After the photo is taken, just open the photo album, find the photo just taken, then pull up the photo and select the last option "Long exposure";

5. Then you can get the photo effect of long exposure.

Long exposure photography is a photography technique of opening the shutter for a long time. It is often used for night photography, ray photography and waterscape photography. Its advantage is that it can make the dim scenery clearer, and it can also take fantastic pictures, such as waterfalls and city roads at night. Long exposure photography needs to use a long shutter speed to capture the image blur of fixed elements, while moving or blurring ugly elements.
