In the first years after its creation, photography was mainly regarded as mechanical reproduction of reality and not as a form of art. Lacking a creative artist that uses his brush to create reality on canvas, photography was widely seen as a technical invention. Therefore 19th century photography mainly focused on improving technique and enhancing chemical processes. Only in the beginning of the 20th century was photography starting to be considered as an art form and small groups of artists accepted photography as a new artistic medium. Since then photography has managed to establish itself as one of the most important forms of art and the development of digital photography and digital processing has widely increased the variety in art photography. Photography is an ideal medium for new collectors as larger editions make it possible to purchase works of renowned artists for affordable prices.
