Why do the photos taken by the camera appear dark when the shutter speed is too fast?

Because the larger the shutter speed value, the faster the speed. The less light that enters the camera, the lower the exposure and the darker the photo.

The higher the shutter speed, the clearer the moving subject; the lower the shutter speed, the blurr the moving subject. Shutter speed represents the exposure time of the camera, generally expressed in terms of time. Such as 1 second, 1/30 second, 5 seconds, etc. The slower the shutter speed and the longer the exposure, the more light will enter the lens.

Shutter speed is mainly used to control the trajectory of the subject's movement. The most common example is high-speed traffic at night. When a high-speed shutter is used to shoot, what is recorded in the photo is the car driving at high speed. When a slow shutter is used to shoot, what is recorded in the photo is the driving track illuminated by the car lights.

Extended information:

Photo brightness is related to sensitivity, shutter time, and aperture size.

1. Adjust the sensitivity. The impact of sensitivity on photography is in two aspects. The first is speed. Higher sensitivity can lead to faster shutter speed, which is easier to understand. The second is image quality. Lower sensitivity brings more delicate imaging quality, and high sensitivity brings better image quality. The noise is relatively large. Generally speaking, the sensitivity should be kept below 800, which is more suitable.

2. Adjust the shutter time. The unit of shutter speed is "seconds". Common shutter speeds are: 1 1/2 1/4 1/8 1/15 1/30 1/60 1/125 1/250 1/500 1/1000 1/2000, etc. The longer the shutter time, the more light will enter, but if the time is too long, shake will make the photo blurry.

3. Adjust the aperture size. The smaller the number behind F, the larger the aperture, the more light that enters, and the brighter the picture. The narrower the focal plane, the greater the blurring of the subject and background; the smaller the number behind F. Large, the smaller the aperture, the less light enters and the picture is darker, the wider the focal plane, the clearer the front and rear of the subject.
