Flash is not allowed indoors. How can a SLR camera shoot sports themes? Like shooting badminton.

Flash is not allowed in general sports events. Photographers who shoot such sports events all use fast lenses. The so-called fast shot means that the aperture of the aperture is large enough, at least reaching f2.8 Only when this aperture is reached can the photographer increase the shutter speed to11000 seconds or more and "freeze" the athletes' movements.

In addition, when watching the ball game indoors, the audience is not allowed to walk around at will, but only between games, which is also the etiquette of watching the ball. Therefore, it is impossible for photographers to go on a rampage like news photography, which requires photographers in fixed positions to be equipped with telephoto lenses, and athletes in shooting venues, such as badminton, need to be equipped with fixed-focus lenses of 200mm, 300mm and 400mm. The maximum aperture of these fixed-focus lenses is still relatively easy to use. f2.8 These "cannon" lenses need to be equipped with a tripod. The reason why they are not equipped with a tripod is that a tripod is more convenient to shoot than a tripod.

When shooting sports events, the photographer first sets the shutter speed, and then sets the aperture value as the maximum value of the lens. If the exposure meets the requirements, he will take photos directly. If the exposure is too large, he will reduce the aperture adjustment. If the exposure is insufficient, he will adjust the sensitivity, usually 800 is enough.

So you can see that the subject of sports photography works is clear, the background is blurred and the motion is fixed, which is the result of using large aperture, long focal length and high-speed shutter.
