Wayne and his producing partner Robert Fellows wanted to shoot the film in the trend-setting 3D format. Warner Brothers supplied the production with the newly developed "All Media Camera," which could shoot in any format, including 3-D, using twin lenses placed slightly apart to produce the stereoscopic effect necessary for it. Despite the fact that they were smaller than the twin camera process used previously for 3D, the All-Media Cameras were still bulky and made the film shoot difficult, causing delays when transporting the cameras to remote desert locations. Further, the director John Farrow and director of photography Robert Burks were unfamiliar with the new technology and had trouble adjusting to using it, while the cameras were frequently broken due to wind blowing sand into the mechanism or from other inclement weather conditions. Farrow used the technology to produce fewer gimmicks than other 3D films did at the time, with only a few scenes showing people or objects coming at the camera, such as gunfire or knives. Instead he preferred to use it to increase the depth of the expansive wide shots of the Mexican desert, or when showing figures against a landscape.
