The word “photography” literally means “drawing with light”. The word was supposedly first coined by the British scientist Sir John Herschel in 1839 from the Greek words phos, (genitive: phōtós) meaning “light”, and graphê meaning “drawing or writing”. The technology which led to the invention of photography essentially combines two distinct sciences: optics – the convergence of light rays to form an image inside a camera –  and chemistry, to enable that image to be captured and recorded permanently onto a photosensitive (light-sensitive) surface.
