The visual effects of 'Odyssey' explained by the cinematographer IMAX 1.43:1 ratio’s real effect

The most talked-about aspect of the Odyssey is the filming, particularly the use of the IMAX format for the entire runtime. Director Christopher Nolan had this dream since his teenage years, and it became a reality after years of research and practice. The impact of this dream can be seen in the surge of ticket purchases at CGV's IMAX auditoriums in South Korea.

Ciné21 spoke with professional Kim Woo-hyeong, who analyzed the significance of IMAX in the filming of the Odyssey. Kim Woo-hyeong, known for his work on films like Bad Movie, The Giving Tree, The Treachery, The Assassination, 1987, and The Impossible, has made several notable films across various genres over the past 30 years. Kim Woo-hyeong's analysis of the filming process reveals how the 1.43:1 aspect ratio of IMAX cameras, compared to the 2.2:1 ratio used in standard cameras, created a unique cinematic experience.

The original IMAX screen ratio of 1.43:1 is different from the 2.2:1 ratio used in standard cameras, which meant that scenes with a mix of both ratios often required constant adjustments during projection. This struggle is not unique to IMAX, as it affected wide-screen formats as well. In essence, the Odyssey stands as the first film to be shot entirely in its original IMAX aspect ratio.

The impact of this decision can be seen in the immersive experience offered by the film, where the screen size and camera movement work together to create a truly unique cinematic experience.
