The Pictoralist photography movement was one of the first artistic styles of the new practice of photography in the late 1800’s. They embraced the inherent nature of early photography emulsions to their advantage by making dreamy, grainy, ethereal landscapes and portraits. Here is the the most famous example. Higher speed film uses a larger grain structure which is one way of the ways one can choose to use photography for artistic expression. In digital photography, this is now achieved by somewhat ironically embracing the high speed settings on cameras as they purport to enable one to make images in darker settings but fail miserably as the grain (in digital parlance, “noise”) is rendered so huge it becomes almost a non-photograph.
