Descrizione IMAGE STANDARDIZATION OF DENTAL PHOTOGRA
The word photography comes from two ancient Greek words: photo, for ¿light,¿ and graph, for ¿drawing.¿ ¿Drawing with light¿ is a way of describing photography. When a photograph is made, light or some other form of radiant energy, such as X-rays, is used to record a picture of an object or scene on a light-sensitive surface. Early photographs were called sun pictures because sunlight itself was used to create the image. With the invention of photography, a realistic image that would have taken skilled artist hours or even days to draw could be recorded in exact detail within a fraction of a second.
