We have faith in the photograph not only because it works on a physically descriptive level, but in a broader sense because it confirms our sense of omnipresence as well as the validity of the material world. 
We have to tell people how images are made. And, the first step is to abandon the idea we’re looking at photographs. We’re looking at entry points to information and to the world in which the image was made.
