Practical Effects vs CGI
Practical effects involve creating physical elements, such as props, makeup, or animatronics, directly on set, offering tangible realism for actors and viewers. CGI, or computer-generated imagery, uses digital technology to create visual effects in post-production, enabling filmmakers to depict scenes or creatures impossible to achieve practically. While practical effects can enhance authenticity, CGI allows for greater creative freedom, and modern films often blend both to achieve the most convincing and immersive results.

❓ Frequently Asked Questions
What are practical effects?
Practical effects are physical effects created on set, such as props, makeup, prosthetics, animatronics, and puppetry, that actors interact with for tangible realism.
What is CGI?
CGI stands for computer-generated imagery. It uses digital software in post-production to create visuals like environments, creatures, and explosions that are not feasible to build on set.
How do practical effects and CGI differ in look and feel?
Practical effects capture real lighting and textures, often yielding a tangible, authentic feel. CGI offers precise control and can depict impossible ideas, but must be well integrated with live-action to look convincing.
Why do filmmakers use both practical effects and CGI?
Using both leverages the strengths of each: the realism and actor interaction of practical effects with the flexibility, scale, and safety of CGI.
What factors influence the choice between practical effects and CGI?
Consider budget, schedule, safety, the level of realism desired, how actors interact with the effect, and whether a shot benefits from on-set authenticity or digital augmentation.
