MUMBAI: Columbia Pictures collaborated with Sway Studio to utilize its expert techniques like macro photography, specialty lighting and animation to create the 3D opening sequence for Robert Luketic's feature film 21.

Utilising these techniques, Sway, an animation, effects and design studio in North America, has shaped a photo-realistic environment mirroring an iconic Las Vegas casino in the adventure film.

"We created a macro world in which the camera travels to within mere microns from the surface of the cards and poker chips. This technique added a level of detail that would have been unattainable for a real-world camera," said Sway VFX supervisor Chris Nichols.

Sway was preferred by VFX supervisor Gray Marshall (Gray Matter FX) and editor Elliot Graham to incorporate a photo-real approach and, thus, adapt the original environment in the film.

Sway's techniques were also required to develop a unique image format that was able to support such extravagant textures. Large lens flares, blinking slot machines and a virtual depth of field gave life to the smoky casino atmosphere.

Columbia Pictures' action film, 21, is inspired by the true story of the very brightest young minds in the country - and how they took Vegas for millions.

The film is based on the book Bringing Down the House, written by Ben Mezrich.

While Elliot Graham has edited 21, William S. Beasley, Brett Ratner and Ryan Kavanaugh are its executive producers.
