How to shoot the explosion plot

It's basically a smoke effect. If there is anyone around.

Early movies, such as a single big house, that is, from the 1980 s to the early 1990 s, were generally made with high-precision scale models. Record it with a high-speed camera. American cameras are awesome. A good camera can shoot a shocking effect even if firecrackers explode. Not to mention the model, it is enough to confuse the real with the fake.

Now, it is basically a green background. As long as the characters perform in front of the screen, many explosion scenes are synthesized by computer. Some companies in the United States have special software for calculating explosion scenes, seawater and so on. It takes a long time and a lot of money to render a frame, but it is true enough.
