How can a mobile phone make the water flow look like silk?

First of all, mobile phones need long exposure function, preferably professional mode. The water turns into silk and slips at least 1 s, and the effect is better in 2-4 seconds, so a stable tripod is needed.

Set the phone, switch to manual mode (also called professional mode), adjust the composition, set the ISO of the phone to the lowest, and set your shutter speed to 2 seconds. Because the mobile phone has no aperture function, it is likely to explode at noon.

If your screen shows overexposure, you can only use a professional dimmer. If there is no dimmer, you can also use sunglasses instead. If it's still overexposed, you'll have to wait until the ambient light is not so bright. Before sunrise or after sunset.

In fact, taking a long lens is the camera's strength, and at least one aperture parameter can be adjusted. The mobile phone has a fixed aperture and can only wait for ambient light or add a reducing mirror to shoot.

The following pictures were taken by my camera and can be used as a reference.

Long exposure module is needed for mobile phone tapping.

Commonly used are Nubian's "electronic aperture" function and Huawei's "streamer shutter"-"silk running water".

The basic principle is very simple, that is, exposure for a long time, recording the path of water flow and "averaging" the moving things.

However, long-term exposure during the day needs to solve the problem of overexposure, and cameras usually adopt the solution of aperture+reducing mirror to reduce the amount of light entering.

The mobile phone has no concept of aperture, so it is simulated by "automatic superposition", multiple superposition and average.

Because the mobile phone has a powerful computing function, the built-in module will automatically calculate, automatically take pictures at intervals, automatically superimpose, automatically align (realize manual long exposure) and so on.

At present, this function can basically achieve manual long exposure, and the picture quality will be slightly worse, but at least the effect can come out.

Of course, it would be better to have a tripod.

Above, using the long exposure function of mobile phone, the movement track of fallen leaves in running water is recorded. The children who move slightly are also blurred, but the fixed railings and ground are real. It gives people a feeling of "the story of running water taking away time".

Long exposure shooting with flowing water produces a fuzzy, foggy and silky feeling, which can remove passers-by.

Long-term exposure to shoot the reflection of clouds and water surface gives the moving clouds a feeling of "drawing".

Example above: The mobile phone is exposed for a long time to record the movement track.

Mobile phone telephoto hand-held long exposure, recording urban rail. On the footbridge, the effect of ordinary tripod is often not ideal, because the footbridge itself will vibrate, and the hand-held long exposure has the function of automatic alignment, which will better help the picture to keep clear.
