Special effects are techniques used in film, television, and theater to create illusions that enhance storytelling. They can be achieved through practical methods, like using props and makeup, or digital methods, such as computer-generated imagery (CGI). These effects help bring fantastical elements to life, making scenes more engaging and visually appealing. There are two main categories of special effects: practical effects and visual effects. Practical effects involve real objects and physical actions, like explosions or animatronics, while visual effects are created digitally in post-production. Both types work together to create a seamless experience for the audience, making stories more immersive.
