In filmmaking a practical effect is a special effect produced physically, without computer-generated imagery or other post-production techniques. In some contexts, "special effect" is used as a synonym of "practical effect", in contrast to "visual effects" which are created in post-production through photographic manipulation or computer generation.[1]

Practical effects often use principles from magic tricks, exploiting the camera's single viewpoint to create convincing illusions that may work only from certain angles, or using specially created props designed to achieve the desired effect. These effects require an interdisciplinary skill set, combining artistic craftsmanship with technical expertise in mechanics and engineering to achieve the desired result.

Many of the staples of action movies are practical effects. Gunfire, bullet wounds, rain, wind, fire, and explosions can all be produced on a movie set by someone skilled in practical effects. Non-human characters and creatures produced with make-up, prosthetics, masks, and puppets—in contrast to computer-generated images—are also examples of practical effects.
