Contrary to what some histories of photography portray, pictorialism did not come about as the result of a linear evolution of artistic sensibilities; rather, it was formed through "an intricate, divergent, often passionately conflicting barrage of strategies." While photographers and others debated whether photography could be art, the advent of photography directly affected the roles and livelihoods of many traditional artists. Prior to the development of photography, a painted miniature portrait was the most common means of recording a person's likeness. Thousands of painters were engaged in this art form. But photography quickly negated the need for and interest in miniature portraits. One example of this effect was seen at the annual exhibition of the Royal Academy in London; in 1830 more than 300 miniature paintings were exhibited, but by 1870 only 33 were on display. Photography had taken over for one type of art form, but the question of whether photography itself could be artistic had not been resolved.
