What leaves a long track when you slow down the door?

I don't know if you have seen it. Literally, it means ray when light moves. For example, traffic at night or stars in the sky, we can use it to shoot different effects. First of all, we need some simple photographic equipment: pay-off, hood and tripod. Because if we want to shoot the track, we need to keep the camera exposed for a long time at night, so we need to ensure the stability of the camera. Not only that, but also some parameters need to be set manually: First, it takes time for light to move, so we need long exposure when shooting the light track. Only in this way can we record the trajectory of the car or light in the photo.

If the shutter speed is too fast, the light source will become a fixed frame photo. And when shooting, our sensitivity should not be set too high, because if it is too high, there will be a lot of noise and the possibility of overexposure.

For light rail photography, the most important thing is the choice of time, because the first condition of shooting light rail is that the car should turn on the light to finish, so Bian Xiao recommends that everyone shoot shortly after sunset.

Because it is not completely dark at this time, you can still see blue and blue, and sometimes you can see clouds. At the same time, most cars will turn on the lights, and the street lights will light up one after another, making the picture feel richer. But if you want to shoot a more pure effect, you can shoot it later.

Since the right time has been chosen, the location is also a very important factor. Again: photography is the art of subtraction, so in the process of shooting, we should try to reduce the appearance of other things and highlight the focus of the trajectory.

So overpasses, tall buildings, or nearby mountains are all good shooting locations. In short, the position should be higher, which can achieve the effect of overhead shooting and show the shooting angle of the light track well. The locations to be photographed are mainly larger intersections and bridges, or more distinctive S-shaped sections and C-shaped sections.
