Photography has always been closely tied to technology. The reliance of the medium on relatively complicated mechanical devices and physical laws is both blessing and a curse. Through photo technology the artist achieves results not traditionally possible with more direct creative methods or simpler tools. Yet, freedom is not complete. The result is constrained by the limitations of the box, a hole through which light is focused, and the recording surface. The possibilities, though vast, are nonetheless finite. There are no purely conceptual photographs or photographers.
