Kodak camera

The Kodak camera was introduced to the world in 1888. It is considered the first easy-to-use, automatic camera. The camera was operated with three steps: Holding the camera steady, the photographer would (1) pull up the string to open the shutter, (2) press the button on the side to make the exposure, and (3) turn the key on the top three times. The key advanced the exposed film so the camera was ready to use again.
The Kodak camera sold for $25 (which is equivalent to around $625 in 2017) and came loaded with enough film to make 100 snapshots. When all 100 pictures had been exposed, the camera was sent to the Eastman Company, where they removed the film, processed the pictures, and then mailed the snapshots back along with the camera with another roll of film inside.
