Before photography was created, people had figured out the basic principles of lenses and the camera. They could project the image on the wall or piece of paper, however no printing was possible at the time: recording light turned out to be a lot harder than projecting it. The instrument that people used for processing pictures was called the Camera Obscura (which is Latin for the dark room) and it was around for a few centuries before photography came along. The first photo picture—as we know it—was taken in 1825 by a French inventor Joseph Nicéphore Niépce. It records a view from the window at Le Gras. In 1839, Sir John Herschel came up with a way of making the first glass negative. The same year he coined the term photography, deriving from the Greek "fos" meaning light and "grafo"—to write. Even though the process became easier and the result was better, it was still a long time until photography was publicly recognized.
If your in the inside trying to take a picture at an upward angle, you risk dropping the camera from where you stand but if your on the top of a building, and place your camera on the ground, you risk having it fall over, or getting damaged by debris from the pollution.
