The Role of Special Effects in Film
When it comes to special effects in films, there are two primary techniques: practical effects and computer-generated imagery (CGI).
Practical effects, also known as physical or mechanical effects, are created using real physical objects and materials. One of the primary advantages of practical effects is that they look and feel real because they are real. When a practical effect is done well, it can be difficult to tell that it's not real. Practical effects can also be more cost-effective than CGI because they don't require expensive computer software and hardware. However, practical effects can be time-consuming and difficult to create, and they may not be able to achieve the same level of detail and precision as CGI.
CGI is a relatively new technique that has revolutionized the film industry. With CGI, filmmakers can create anything they can imagine without the limitations of the physical world. CGI allows filmmakers to create visuals that would be impossible or too expensive to create using practical effects. However, CGI can be expensive and time-consuming, and it requires a significant amount of technical skill and knowledge. Additionally, some argue that CGI can look too perfect, making it feel less real than practical effects.
Ultimately, the decision to use practical effects or CGI comes down to what the filmmaker wants to achieve with the film. Both techniques have their advantages and disadvantages, and the best choice depends on the specific needs of the film.
