What are practical effects?

Practical effects, also known as physical effects or in-camera effects, are techniques used in filmmaking to create visual illusions or manipulate the environment directly on set, rather than relying solely on computer-generated imagery (CGI) or post-production editing. These effects are created through the use of props, models, makeup, animatronics, pyrotechnics, and other physical elements.

Practical effects have been employed in the film industry for decades, even before the advent of CGI. They involve the manipulation of real objects, substances, or physical forces to achieve desired visual or sensory effects.

Some common examples of practical effects include:

Miniatures: The use of small-scale models to depict large objects or environments, such as buildings, spaceships, or cityscapes. These models are often filmed alongside live actors to create the illusion of interaction.

Prosthetics and Makeup: The application of prosthetic devices, masks, or makeup to alter an actor's appearance. This can range from subtle enhancements to elaborate creature designs or character transformations.

Pyrotechnics: The controlled use of explosives, fire, or other combustible materials for creating realistic explosions, gunfire, or other dangerous effects.

Stunt work: The performance of action sequences by trained stunt performers, involving physical feats, fights, falls, and other high-risk maneuvers. Safety measures are taken to protect the actors and stunt performers during these sequences.

Animatronics: The use of robotic or mechanical devices to create lifelike movements in creatures or objects. This technique is often employed in creating realistic animals, monsters, or humanoid characters.

Special effects makeup: The creation of realistic wounds, injuries, or transformations using materials like latex, silicone, or other prosthetic materials. This is often used to simulate injuries, monsters, or fantastical creatures.

Puppetry: The use of puppets or marionettes controlled by puppeteers to create lifelike movements and performances. This technique is commonly employed in creating creatures or characters that are difficult or impossible for actors to portray directly.

The use of practical effects can provide a tangible and realistic quality to a film, enhancing the audience's immersion and suspending disbelief. While CGI has become increasingly prominent in modern filmmaking, practical effects still play a crucial role in creating practical and visually convincing elements on screen. Many filmmakers strive to strike a balance between practical effects and CGI to achieve the desired aesthetic and storytelling goals.
