One creative solution was uncovering Peter Parks, a specialist in macro photography, who had retrieved deep-sea microorganisms and photographed them in 3-D under partial funding from the Bahamas government. Parks brewed chemicals and bacteria together to create reactions that Schrecker and Dawson shot, recording 20,000 feet worth of film over eight weeks. To create the effects, Peter Parks took advantage of fluid dynamics, which affected the behavior of the substances that he photographed. "When these images are projected on a big screen, you feel like you're looking at infinity. That's because the same forces at work in the water—gravitational effects, settlement, refractive indices—are happening in outer space," Parks said. The specialist's talent convinced the film's creative department to go beyond computer-generated imagery and follow Parks' lead. Instead of millions of dollars for a single special effects sequence, Parks generated all the footage for the film for just $140,000.
