What did George Eastman develop in 1884?

• A. The first roll film
• B. The first motion picture camera
• C. The first electronic television
• D. The zoopraxiscope

Answer: (A)

The idea being tested is how a major shift in how photos are made changed photography. George Eastman’s 1884 development of the first practical roll film was a pivotal move from bulky glass plates to a flexible, wound film. That single innovation made cameras portable and simple to use, because you could carry multiple exposures on a single roll instead of loading and changing glass plates for each shot. It opened the door to amateur and mass-market photography and set the stage for the later consumer Kodak cameras that popularized taking pictures for everyday people. The other options come from different inventors and times: a motion picture camera was developed later by others; the zoopraxiscope was an earlier projection device by Muybridge; electronic television emerged in the early to mid-20th century. Eastman’s roll film is the development that directly enabled convenient, widespread photography in 1884.
