Headed by David Womersley, live-action photography units shot on actual jungle, beach, and desert locations including California, Florida, Hawaii, Australia, Jordan, Venezuela, and Samoa. In total, two live-action film crews shot more than 800,000 feet of film, although one scene, which takes place inside a cave, utilized a computer-generated background. In order to approximate a dinosaur's perspective, visual effects supervisor Neil Krepela invented the "Dino-cam", in which a camera was rigged on a cable suspended between two 72-foot-tall towers. The computer-controlled camera allowed for panning and tilting on 360 degrees and moved at up to 30 miles per hour across a span of 1,000 feet. With the live-action elements shot and the character animation reaching completion, the footage was moved into the Scene Finaling department. Under Jim Hillin, the effects-compositing team blended 80–90 percent of the live action plates against the computer-animated characters. The lighting department then adjusted the final lighting of the shots by changing the lighting conditions and replacing the skies.
