How to shoot the light track with a SLR?

First, you need a tripod, and it should be relatively stable. If it wobbles, you can throw it away. Because the SLR is heavy, it takes a long time to shoot night scenes or car light tracks. If there is no tripod or the tripod does not move, the picture will be blurred. I don't care whether your camera and lens are good or not, but don't shoot night scenes and landscapes without tripods. For convenience, it is best to use a mobile phone.

In fact, no matter what you shoot, you will always adjust the three parameters of ISO, aperture and shutter. The correct exposure is composed of these three parameters. In fact, these things are all dead and should be adjusted according to the brightness and exposure of the ambient light at that time.

However, you should still be a beginner, so let's take the car light trajectory as an example: use manual or aperture priority mode, the aperture is around F8, ISO 100, and then see how long the shutter time is. B-door will be used in 30 seconds. 750D should not have a high sense, so generally don't use a higher ISO, but don't lose heart. I didn't say 750D couldn't make a good film. This has something to do with the shooting method and the later stage. This is beside the point.

I haven't used Canon 750D. I don't know how many wheels it has Need to enter the menu to adjust the parameters? I use 5D3, so I don't have to go into the menu. Take this as an example. Turn the dial on my left shoulder and set it to Aperture Priority (AV). Adjust the aperture with the thumb wheel of my right hand. In aperture priority mode, only ISO size and aperture size can be adjusted, and the shutter is determined by the camera. By the way, ISO is the button that says ISO on the right shoulder of the camera.

Read the instructions. Although it is the same brand, there are some differences in some operations of different models. Instructions are the best course.
