Because most kicks are circular, there is a lot of body rotation around the center of gravity. This makes Capoeira practitioners appear a bit slow, for martial artists. They are not. If you look at how fast the feet move, well, let's just say these pictures are all shot at 1/1600s. If there had been more light, I would have shot at an even shorter shutter time.
The high jumps are impressive. To capture them, I set the camera to shoot high speed bursts.
I also switched from RAW to JPEG format. The drawback is that I loose a bit of information, so I can't bring out details in shadows, nor reduce highlights as well as I could with a RAW picture.
The advantage is that the pictures are much smaller, so I can shoot long bursts without the camera's memory buffer filling up.
Another advantage is that the pictures require less storage space. I shot about 600 pictures in 20 minutes.
It helps if you start young, of course.
