I want to ask my photographer a question: Can exposure compensation balance exposure? If you want to shoot the trajectory, you need 1 second exposure. I use

There is something wrong with this concept. First of all, the exposure compensation value is only a value when you do it manually, so that you can know whether it is overexposed or underexposed. If the minimum ISO and the minimum aperture have been set, and the exposure time of 1 second is needed, and the exposure compensation value at this time is +2, you can choose to take a picture first (in the case of a digital camera). That's actually telling you that the limit of what you use is like that. You need to add other equipment to change the problem of overexposure. One of them is a dimming filter, which can reduce the amount of light entering the camera. Another method is to block the light source, such as putting a sun visor in the sun. But if you can't block the light source in the light, then there is only a dimmer.
