Visual effects, often abbreviated as VFX, are techniques used in film, television, and video games to create imagery that cannot be captured during live-action shooting. These effects can enhance scenes by adding elements like explosions, fantastical creatures, or entire landscapes that are digitally created or manipulated. The process of creating visual effects involves various software and tools, allowing artists to blend real footage with computer-generated imagery. This combination helps to tell stories in a more engaging way, making it possible to visualize concepts that would be difficult or impossible to film in reality.
