How to use a mobile phone to capture traffic flow, the best time-lapse photography effect

Answer 1

To get the best effect of time-lapse photography with your phone, you can refer to the following points:

** 1. Initial preparations **
1. ** Equipment stability **
- Turn on the flight mode. Because time-lapse photography takes a long time to shoot, it will prevent the camera from stopping shooting when the call comes.
- Use a tripod to keep the phone stable. You can hang heavy objects (such as school bags) under the tripod to increase stability. Although the phone has anti-shake function, for time-lapse photography, a slight shake will affect the image.
2. ** Scene selection **
- Choose a scene with a lot of traffic, such as the main road of the city, viaduct, etc., to ensure that there are obvious changes in the image, so as to avoid the delay of the video like a photo.
3. ** Setting parameters (if you use the phone's own functions)**
- ** Speed selection **: Multiple speeds of different phones are suitable for different scenes. For example, 15X is suitable for shooting traffic, pedestrians, etc. If the speed control was not good, he could choose a low multiplying factor first and then speed up according to the needs later. This was because if he chose a high multiplying factor in the early stages, it would be more difficult to slow down in the later stages.
- ** Other parameters (using some phones as an example)**: Find more and open time-lapse photography, click on auto, adjust the speed to 90x, and choose unlimited recording time. Then, he clicked on the Pro mode, adjusted the sensitivity to 125 to ensure the quality of the image, and adjusted the white balance to 6500K to control the color. He tried to shoot at a high place with heavy traffic in the evening or at night.

** 2. Filming process **
1. ** In terms of composition **
- You can use composition skills, such as arranging lines such as the horizon in the picture. For example, when the horizon is located at the bottom 1/3 of the picture, the sky takes up a larger space, which can make the picture look broader and more magnificent. When the horizon is located at the top 1/3 of the picture, the ground takes up more space, which is suitable to highlight the main body of the ground, such as traffic.
2. ** Manual operation (if using professional mode)**
- If you wanted to take a time-lapse photo of a traffic flow with a drag effect at night, turn on the camera's professional mode and extend the shutter time while ensuring that the picture was not exposed. The longer the shutter time, the more obvious the drag effect. Since it was necessary to ensure that the shooting parameters of each photo remained unchanged, after setting up the camera and setting the photo shooting parameters (such as aperture, USB, white balance, etc.), you could use the third-party app-auto-click to press the shutter. The time between each shutter press needed to be set according to the actual situation. For example, factors such as the exposure time of a photo taken by the phone and the time to process the photo needed to be considered.

** 3. Post-processing **
1. After the shooting was completed, he could use the powerful photo editing software on the market, such as S, Vsco, LM, etc., to cut, color, add filter, and other operations to improve the picture quality.
2. If you need to combine the photos into a video (in the case of manually taking photos), you can import the photos into video editing software (such as Adobe Premiere Pro, Final Cut Pro, etc.), set a reasonable frame rate (such as 24fps, 30fps or higher), and perform color correction, stabilize the image (if there is slight movement), edit the material (remove unnecessary parts), add transition and music, and so on to export the final time-lapse video.
