Candid Camera's Allen Funt secretely tapes people's reactions to unexpected encounters with nudity in unusual situations, such as when a naked young woman casually exits an elevator in an office building, or when the nude male art model breaks the wall between artist and model and has off-the-cuff conversations with the clothed women artists. Funt also secretly tapes the test audience watching the preview film and their responses to it, from outright indignation to warm hearted-praise.
