How to become a racing photographer

1. The faster the moving speed of the subject, the faster the shutter speed should be used; The so-called inverse ratio means that the shutter speed is inversely proportional to the distance between the subject and the lens. The closer the distance, the faster the shutter speed. If the distance is long, the shutter speed is relatively slow. Generally speaking, in the case of poor light, it is usually very weak to shoot objects moving at high speed in the distance with a good camera whose shutter time exceeds1125 seconds. 2. Ensure sufficient light. Ordinary cameras can't set the shutter speed and aperture size manually. Therefore, if you shoot a high-speed moving object, you can only enlarge the aperture appropriately, turn on the flash and strengthen the exposure value. However, these measures are also limited to long-distance subjects, and they can only rely on sufficient illumination to shorten the shutter time as much as possible and ensure clear pictures. If the subject moving at high speed is a very precious lens, remember to take more shots at a time, and then you can choose a satisfactory one. 3. Fixed focus value When shooting fast-moving scenes, the focus speed of digital cameras is very important. If the focus speed is not fast enough, it is easy to miss the fleeting picture. The reality is that most good digital cameras do not have high-speed focusing ability, so we must find another way. If you can predict the trajectory of a moving object in advance, set all the parameters of the digital camera first, but aim the lens at the prediction point and press the shutter half-way, and then the digital camera will remain in focus. 4. The interpretation of "dynamic" is not necessarily a bad thing, because the movement is very fast, and sometimes it can show certain artistic effects, such as the flight trajectory of the ball when shooting in a football match, or the racing driver who is moving at a high speed. Simply put, move the camera smoothly along the moving direction of the target, so that the position of the target in the viewfinder is always the same, and press the shutter while moving. This method can be used to photograph moving objects. Its effect is that the foreground image is clear and the background is blurred, which can avoid the messy background from destroying the picture.
