What do you mean by special effects in previous movies?

The previous film special effects refer to the special effects technology adopted in the early stage of film production. Early film special effects include model shooting, animation, holography, mechanical special effects, chemical special effects and so on. These special effects techniques are based on traditional hand-made methods, which need to consume a lot of time, manpower and material resources. Although these special effects are not very realistic compared with the current CGI technology, they were already very advanced technologies at that time.

In the sixties and seventies, the film special effects technology began to develop rapidly, and the special effects that needed to be made by hand began to be replaced by computers. During this period, classic films such as "Galaxy Warrior" and "Star Wars" appeared. These films use new special effects technology to create more realistic, complex and amazing picture effects. With the continuous development of special effects technology, film production has entered a new era.

With the passage of time, the film special effects technology has been developing continuously. New technologies are constantly developing, creating more realistic and shocking picture effects. Nowadays, special effects technology can realize the interaction between people and things, elaborate plane and animation design, and create a completely fictional environment. Modern special effects are widely used in movies, television, games and other fields, bringing us more wonderful visual experience.
