Photography was first a scientific invention. It immensely simplified the art of image making. Soon after its invention, photography became not only a tool for image making, but also a medium of expression. By the turn of the early 20th century, it was slowly accepted as a form of visual art.
While other forms of image making such as painting and sculpture were limited only to the elite class, the intervention of photography gave access to the world of image making even to the lowest economic class. It became so accessible that it is used in almost all walks of life. It is the fastest medium of communication; as the saying goes ‘seeing is believing’, photographs do not require letters and symbols to be read. Anyone who is not visually disabled is literate to read photographs and interprete it in his/her own understanding.
