Can I take slow-motion photography with my mobile phone? How should I take it?

At present, most mobile phones can realize slow door photography. Apple mobile phones generally need the help of third-party apps, such as NightCap and other apps, which can achieve a very rich slow door effect. However, such apps are generally charged, so ordinary users rarely use them. Most Android phones have their own "professional mode", in which you can usually find options for adjusting the shutter speed.

As shown above, there is an aperture icon next to the red shutter button, and "110" below stands for110 second shutter. On the turntable on the left, the shutter speed can be adjusted from 1/8000 to 30 seconds. Generally speaking, the stronger the light, the higher the shutter speed. When the light is weak, it takes 1 sec or even longer to gather the light. Relatively speaking, Huawei's mobile phone is better than other mobile phones at night. Most mobile phones support the "super night view" function, and you can get a very clear night view effect with it. Compared with SLR cameras that need to manually adjust the slow door time, Huawei's "Super Night Scene" can automatically set the slow door time according to the ambient light, so it is more intelligent and convenient.

For example, the above picture was taken in normal mode. Although the overall picture is clear, there are some overexposures, and the noise in the sky is also obvious.

The above picture shows the photos taken at the same location using Huawei's "Super Night Scene" mode, 1 1 second slow shutter and built-in algorithm. Not only the local highlights of the picture are pressed down, but also the vision is very clear, and the sky is very transparent without noise. Compared with the slow door mode of ordinary SLR, the slow door of Huawei mobile phone is smarter. For example, directly blur the traffic on the road, so that there will be no bright lines caused by vehicle movement in the photo. Of course, if you deliberately want to achieve that effect, you can also shoot through the "traffic" mode that comes with your mobile phone. Usually, a slow-door night shot like the above requires a tripod or other props to stabilize the fuselage, otherwise the picture will be blurred because of the jitter of the fuselage under long-term exposure. But Huawei P20

Many models after Pro also have a "hand-held super night scene" function, which can realize a hand-held slow shutter for up to 8 seconds without a tripod.

However, the principle of Huawei's "handheld super night scene" is different from the usual slow shutter of SLR. It takes countless photos in 6 seconds, and then stacks them layer by layer to improve the brightness of the picture. At the same time, through the powerful computing performance of Kirin processor, the positions of these photos are constantly corrected to avoid the blur caused by hand-held shooting. Although the photos taken by Huawei's "handheld super night scene" are still not as clear and transparent as the slow shutter realized by the tripod, getting rid of the shackles of the tripod also allows users to easily take clearer night photos.
