What is CGI ?

 CGI, or Computer Generated Imagery, is the use of computer graphics to create realistic or fantastical images in movies, television shows, video games, and other forms of media. It has revolutionized the way that visual effects are created and has given filmmakers the freedom to create worlds and characters that were once impossible to achieve with traditional special effects techniques.

One of the earliest uses of CGI was in the 1973 film, Westworld, where the use of computer-generated imagery allowed for realistic depictions of the android characters in the film. It wasn't until the 1990s, however, that CGI became more widely used in movies, such as Jurassic Park and the Star Wars prequel trilogy. These films showcased how CGI could be used to create creatures and environments that were otherwise impossible to capture on film.

Today, CGI is used in almost every major film, whether to create entire worlds in the Marvel Cinematic Universe or to enhance the realism of practical effects. In fact, many modern films rely on CGI so heavily that it can be difficult to distinguish what is real and what isn't on screen.

 One of the major benefits of CGI is its ability to save time and money in the filmmaking process. With traditional special effects techniques, creating practical effects can be time-consuming and expensive. CGI can often accomplish the same task in a fraction of the time and for a lower cost. This allows filmmakers to focus on other elements of the film and spend more time on storytelling and character development.

Despite its many benefits, some filmmakers and audiences still criticize the use of CGI. Some argue that it can take away from the authenticity of a film, and that relying too heavily on CGI can create a sense of detachment from the story and characters.

Overall, CGI has changed the way we create and experience visual effects in film and other forms of media. As technology continues to advance, it will be interesting to see how CGI will evolve and how it will continue to impact the art of filmmaking.
