Digital effects are techniques used in film, television, and video games to create or enhance images using computer software. These effects can range from simple adjustments, like color correction, to complex animations and 3D models. They help bring imaginative worlds and characters to life, making stories more engaging for audiences. Common types of digital effects include visual effects (VFX), which are added in post-production, and computer-generated imagery (CGI), which involves creating images from scratch using 3D modeling software. These tools allow creators to produce stunning visuals that would be difficult or impossible to achieve with traditional filming methods.
