My great-grandfather was an avid photographer who owned his first camera in 1888. The document discusses the evolution of camera technology over time from my great-grandfather's early box camera that projected images on a wall to modern digital SLR cameras. It explores the basic parts and functions of a camera, including how light enters through the lens and aperture and is reflected through the viewfinder, as well as defining the key roles of the lens and aperture in regulating light exposure.
