Practical Effects vs. CGI: Debunking Myths and Achieving Visual Storytelling

Contrary to popular belief, some directors and producers still insist on using practical effects wherever possible. The team behind films like Hereditary have proven that it’s not only feasible but can also bring an added level of realism and authenticity to a production. A prime example is a scene in Hereditary where a small chalkboard lying on a table is chalked on by an invisible hand.

Through meticulous planning and innovative techniques, the filmmakers managed to implement a real piece of chalk and a strong magnet under the table to create the effect. The result was a seamless scene that didn’t require the audience to pause and question the authenticity of what they were seeing.

Case in Point: Minimal SFX and Practical Effects in Action

The use of minimal special effects (SFX) and the reliance on practical effects has been a hallmark of films like Fury Road. Most background elements were achieved through practical means, showcasing a raw and visceral approach to storytelling. This method focuses on the tangible and physical, allowing the audience to feel more connected to the action on screen.

Similarly, Once Upon a Time in Hollywood also utilized very little CGI, with most of the sets being reconstructed to recreate the authentic 1960s Hollywood. The choice to use practical effects not only added to the authenticity of the film but also allowed the audience to fully engage with the environment and the characters.

Combining Practical and CGI for Seamless Visuals

The best approach often lies in the judicious combination of practical effects and CGI. For instance, in newer Star Wars films, the enhanced use of practical elements paired with CGI results in a more immersive and believable experience. This technique ensures that the CGI seamlessly integrates with the practical elements, making the entire visual story cohesive and impactful.

A better alternative to greenscreen techniques is the use of projection systems, showcased effectively in Oblivion. This method allows filmmakers to project realistic elements onto the background and onto objects in the foreground, creating a more dynamic and immersive visual environment. This technique not only enhances the visual storytelling but also allows for more complex and dynamic scenes to be achieved without the limitations of traditional greenscreen methods.

Bridging the Gap: Practical Effects in Modern Filmmaking

False premise: While some may assert that practical effects have become obsolete, it is worth noting that these techniques are still widely used in modern filmmaking. Practical effects such as squibs (fake blood), SFX makeup, and pyrotechnics are still integral parts of the industry. These techniques offer unique advantages that CGI cannot easily replicate, such as texture and unpredictability, making them a valuable asset in a filmmaker’s toolkit.

Take, for example, the use of squibs in action scenes. These are small explosions that simulate the popping and spraying of blood, creating a visceral and realistic effect that can’t be achieved through CGI alone. Similarly, SFX makeup, like prosthetics and set dressing, adds a tactile and authentic element to characters and environments. In films like The Expendables or Die Hard, the use of these practical effects enhances the overall impact of the action and the believability of the characters and their surroundings.

Conclusion

Practical effects continue to be a vital component of modern filmmaking, offering authenticity, realism, and unique textures that CGI often can’t replicate. By embracing these techniques and integrating them with cutting-edge CGI, filmmakers can achieve a level of visual storytelling that resonates with audiences on a deeper, more emotional level. The key is to use the right tools for the job, ensuring that each choice enhances the story and the viewer’s experience.

So, the next time you watch a film, take a moment to appreciate the details. Practical effects play a crucial role in creating memorable and engaging visuals, proving that they are far from obsolete and will continue to thrive alongside the advancements in digital technologies.
