Shoot with a cannon

Generally speaking, on the issue of shooting shells or bullets, as far as shooting is concerned, the technical conditions can achieve image capture. As long as there is enough light, there is no problem in using high-speed cameras, such as phantom shooting. As long as the position is set, the wide angle is set, the hyperfocal distance is calculated, the focus ring is tightened, and the pan/tilt is locked, the cannonball can be fired without brains. According to the parameters of the shell, the angle from the camera to the muzzle, flight time and landing point can be obtained.

That is to say, the angle and speed of the camera direction and the pan/tilt that needs to be rotated are obtained, and the equipment such as motion control is used to follow and shake, and the flight speed is as high as several Mach. Therefore, shooting at a long distance with an ultra-long focal length, because the distance is too far, the camera needs to shake a little, and the angular velocity provided by the equipment is not high, so shooting can be completed completely. The focus can also be controlled by motion, and then, because many guns use electric firing mode.

So I just need to do some tricks to connect these two devices and trigger the shooting equipment. Usually, high-speed photography will be widely used in the following topics, such as sports, sports, animals, birds and so on. To photograph the specific state of things when they are moving, which is like turning the movement process into a decomposition state. This kind of photo is what I want to achieve in high-speed photography. The decisive moment refers to the photographer's perfect combination of all factors such as form, imagination, composition, light and events at a specific moment.

Especially by capturing decisive things, summarizing them in a very short second and expressing them with powerful visual composition. Bresson put forward the most famous decisive moment in the history of photography. He believes that everything in the world has its decisive moment. He decided to capture the moment of ordinary life with the photographic style of the decisive moment, and grasp the appearance and connotation of things in a very short time to make them eternal. ?
