What shooting occasions are high-speed shutter and slow door used for respectively?

The high-speed shutter is used to shoot fast-moving objects, while the slow shutter is used to display strange pictures (such as traffic and water) caused by dynamic blur.

High-speed shutter means that the shutter releases light (exposure) for a very short time, which will reduce the brightness of the picture and clearly solidify the subject moving at high speed.

The slow gate is a long-time light release (exposure), which is very slow. The moving subject in the picture will leave a running track, which will become blurred and the brightness of the picture will be improved.

The unit of high-speed shutter speed is seconds. When in use, press the shutter lightly or half-press the shutter, and the autofocus symbol of the viewfinder will flash. If there is a sound prompt, it will make a "beep" twice. This camera is in autofocus and photometry. In this process, the camera is also running, and the next program can only be carried out after this program is completed. Then, with a little effort and a little effort, it can be completed.

When taking pictures, you should not only practice basic skills, that is, holding bricks with one hand, but also try to find support. Learn to control your breathing when taking pictures, and take a breath before pressing the shutter. Be calm when taking pictures, control your emotions and don't be nervous. If you are shooting a moving object, you should press the shutter in advance, and your brain should analyze and predict each other's movements and rhythms.
