Visual effects (VFX) are the techniques used to create or enhance imagery in videos, films, and digital content that cannot be captured during live shooting. They involve adding elements like explosions, weather effects, creatures, or imaginary environments using computer-generated imagery (CGI).A well-executed visual effect blends seamlessly with real footage, focusing on realism, timing, lighting, and detail to make scenes more immersive and believable. Artists use advanced software and creative skills to bring ideas to life that would otherwise be impossible or too costly to film.Overall, visual effects play a crucial role in modern media, enhancing storytelling and creating stunning visuals that captivate audiences.
