John Toll, ASC Goes Digital for Iron Man 3

Toll, who won Oscars for Braveheart and Legends of the Fall, and took home a third nomination for The Thin Red Line, teamed with director Shane Black and actor Robert Downey, Jr. on the film.

"I was very interested in doing a movie with digital cameras and exploring the whole medium," says Toll. "I love film, but obviously, there are reasons to use digital cameras on certain projects. Iron Man 3 was a good opportunity for me because I had the resources to do a lot of testing and to really explore how digital cameras work. I think part of the whole attraction of the digital world is convenience, especially for big visual effects movies. I thought it made sense for this project."

Toll chose to go with the ARRI Alexa Studio camera with Codex Recorders to capture images in ARRIRaw format.

"We were recording the 14 stops of range that the Alexa claims," says Toll. "If we needed to access that enormous amount of information down the road, for visual effects and in the DI, then we could. That additional information was the reason we chose to go with the Codex workflow and ARRIRaw."

Marvel Entertainment has used Codex Recorders on a number of pictures, includingThe Avengers, shot by Seamus McGarvey, ASC, BSC and the upcoming Thor: The Dark World, shot by Kramer Morgenthau, ASC.

The Iron Man 3 production also used the Codex Vault, an on- or near-set media management solution that facilitates faster, dependable transfers and archiving, and eliminates complexity in file-based workflows. Marvel's senior vice-president of postproduction, Bruce Markoe, says his goal is to standardize the workflow from movie to movie on Codex.

"We plan to use Codex on upcoming movies as well," says Markoe. "I consider it to be a rock-solid platform. The Codex Vault in particular is a great choice for both efficiency and capability. We just purchased some of the new, smaller Codex recorders and Capture Drives, which represent a significant advance both in terms of flexibility and price point. It's an attractive format that we plan to continue to utilize."

Digital Imaging Technician (DIT) Ryan Nguyen helped make the process seamless for Toll. "I used the Technicolor DP Lights system to create CDLs for all the shots," says Nguyen. "Once John was introduced to what can be done on set, he was really into it. He saw what a great tool it could be, and often he would make tweaks in lighting or exposure based on what he saw on the monitor."

Generally, the Codex was onboard the camera, but in some situations - if the camera was on a crane or in another unusual configuration - it was connected via fiber-optic cable.

"Using the Codex Transfer Drives and the Vault sped up the process," says Nguyen. "The Codex was dependable under very difficult conditions - there was a lot of location work in North Carolina, and we were constantly dealing with heat and rain."
