Two cameras were loaded with color film, one with positive (slide)film and one with negative (print) film. The other two cameras were loaded with high resolution black & white film and infrared black & white film . The exact combinations of film, filter and aperture were based on extensive testing done by the Can Do Technical team with the advice and consultation of the expert staff at the National Geographic Society in Washington DC.
