How to shoot traffic tracks?

1. Choose a shooting location

If you want to take good-looking photos of traffic tracks, the composition and framing of the picture are very important, so we need to choose different shooting locations based on the expected shooting effects. Location.

First of all, when we take photos of train tracks, most of the roads we choose are curved roads, or even roads with continuous curves, so that the photos of the train tracks taken will have a more layered and linear feel.

Then, it is best not to have office buildings or shopping malls with complex lighting effects on both sides of the road we choose. These lights will form bright spots under longer exposure, which is not good for us. Express the traffic trajectory and affect the beauty of the picture.

Finally, it is generally recommended to choose overhead shots from overpasses, high-rise buildings, etc. for shooting locations. The traffic trajectories photographed on overpasses are usually relatively straight, while the traffic trajectories photographed on the roofs of high-rise buildings can be more complex. traffic trajectories.

2. Traffic flow

The traffic flow on different roads is different. At this time, the traffic flow on the road will affect the choice of the shutter speed of our camera. If the traffic flow is large, The shutter speed can be adjusted faster; if there is less traffic, the shutter speed should be adjusted slower.

When the traffic volume on the road is large and the vehicle speed is fast, adjusting the shutter speed to about 4 seconds can obtain very good traffic trajectory photos, and the number of vehicle tracks in the picture is also relatively high. Rich.

When the traffic flow on the road is very small, in order to obtain richer traffic trajectory photos, a longer exposure time is required, which affects the adjustment of parameters such as aperture and ISO. Sometimes it may also be necessary A dimmer filter reduces the amount of light entering to maintain a longer exposure.

3. Shooting mode selection and exposure control

When shooting traffic tracks, it is recommended to choose shutter priority mode most of the time, or choose manual exposure M mode to shoot, which is enough. After all, there are many Sometimes there is no need to use an exposure time of more than 30 seconds. When we occasionally need to use an exposure time of more than 30 seconds, the shooting process is similar to the manual exposure mode.
