Ansel’s favorite analogy was that the negative was the musical score and that making the print was the performance. Sofar in this description of the Zone System we have described all the technical details of making negatives that optimallyrecord the range of light in the scene. We have described Ansel as a skilled recording specialist for light. In making theprint Ansel’s role changed dramatically. He became the performer of the score in the negative. He became theinterpreter of the optimally stored information. The tone-scale functions that he studied and mastered were necessary,

but not sufficient to render his visualization of the scene. Spatial manipulation of light projected from the negative ontothe print paper was needed to successfully render the visualization. Each scene required a unique spatial intervention.
