In 1855, George Eastman of Rochester, New York made a device that attached to almost any camera to hold rolled-up photographic paper. The paper replaced the glass slides previously used. In 1888 he decided to market his own camera. This would be cheap to make and simple to operate, and the original Kodak model could film for 100 images. When they were exposed, the consumer sent the entire camera back to the factory for processing. Other models followed. This Model 3A Folding Pocket camera was one of the most popular ever made. It was manufactured from 1903 until 1934 (with modifications). One of its most popular features was that it made an image that was 3 1/4" x 5 1/2". Earlier Kodak cameras and the cameras of its rivals made pictures that were only 2 1/4" x 3 1/4". A bigger image meant that pictures did not have to be enlarged after they had been processed, and that saved money.
