CGI, or Computer-Generated Imagery, refers to the creation of still or animated visual content using computer software. This technology is widely used in various media, including films and documentaries, to produce realistic images and effects that would be difficult or impossible to capture in real life. CGI enhances storytelling by allowing filmmakers to visualize concepts, environments, and characters that might otherwise only exist in the imagination.

Review Questions
How does CGI contribute to storytelling in documentaries?
CGI plays a significant role in storytelling by allowing filmmakers to visualize concepts that are hard to depict through traditional filming methods. For instance, when documenting scientific theories or historical events, CGI can create representations that help the audience grasp complex ideas. By using CGI, filmmakers can enhance the narrative flow and make their stories more engaging and accessible.
Discuss the balance between using CGI and practical effects in documentary filmmaking.
Balancing CGI and practical effects is crucial for maintaining authenticity while achieving desired visual results. Practical effects provide tangible elements that enhance realism, while CGI allows for creative possibilities that practical methods might limit. By thoughtfully integrating both techniques, filmmakers can create a compelling narrative that resonates with viewers without sacrificing credibility.
Evaluate the impact of CGI on viewer perception and understanding of documentary content.
CGI significantly impacts viewer perception by shaping how they interpret and engage with documentary content. When used effectively, it can enhance understanding by visually simplifying complex subjects, thus making them more relatable. However, there is a risk that over-reliance on CGI could lead viewers to question the authenticity of what they see, blurring the lines between fact and fiction. Therefore, it's essential for filmmakers to use CGI responsibly to maintain trust with their audience.
