For example, high-speed cameras take pictures of bullets passing through apples.

If it is a video, it will be easier. Shoot apples continuously with a medium telephoto lens, and the bullets will be recorded naturally when they pass through.

If it is photography, the requirements for equipment are higher. First of all, it must have a high continuous shooting speed, such as 12 frames per second like 1DX, and a strong light source (always on), because it is necessary to ensure that the shutter speed matches the bullet speed to make the picture freeze at the moment when the bullet passes through the apple. When shooting, use a tripod to fix the position, focus on the apple, and use a small aperture to ensure the depth of field.
