Instead of returning exposed film in reentry capsules, NASA had the Lunar Orbiters scan the film in space, convert brightness measurements into radio signals, and transmit them to deep-space communication centers in Spain, Australia, and the United States, where the images were reconstructed from magnetic tape.
Notes on verification
Corroborated by multiple independent, credible sources including space history archives, NASA-affiliated project blogs, and Wikipedia, all consistent in describing the scanning, transmission, and reconstruction process at the three named ground stations.
