Response to O'Donovan's Questions:
a) In this photograph, John Anderton's face is half shaded. The part of this photo that caught my eye the most was the sweat on his face. The sweat helps the viewer understand the state that John was in during this moment, and that he may have been either in a hurry, or very anxious.
b) John Anderton's face is the only noticeable part in this screenshot, because the image only consists of his head before a black background. Half of John Anderton's face is visible, making it foregrounded, while the shaded half of his face is more backgrounded. The image does this to show a point in the movie in which John was hiding something, so in other words he wasn't revealing his true self within the moment of this screenshot.
c) The image is displaying John Anderton's half-shaded face because throughout the movie, you watch John Anderton try to hide himself from the PreCrime system, as well as when he tries to hide his "substance-abusing" side. The way this shot was taken actually remind me of the Yin vs. Yang concept. Stemming from this concept, it makes sense that the right side of John's face was the side that was shaded, because that is the more sensitive yet negative side, the Yin. The visibility of the left side of his face, the Yang, shows that he chooses to show his more masculine, positive side. However, this may not have been Spielberg's goal when filming the movie, but I just thought it was an interesting coincidence.
d) Other parts of this image that better my understanding of John's given situation is the location in which his eyes are aiming. He seems to be looking towards a point that appears to be to his upper-left, so clearly he notices something up there that may either enhance or reduce his stress (the stress is shown through the sweat on his face).
