The manner in which Shadow uses her pinhole camera is incorrect. For example, when she takes the picture of Treasure, she removes the cover from the pinhole and leaves the pinhole uncovered for a much longer period of time than required (correct time is 2-3 seconds vs. the 15-20 seconds "Shadow" leaves the pinhole uncovered). In addition, she leaves the pinhole uncovered until Treasure turns and walks away from her, and only then does she cover the pinhole. When we see that picture later, it is a perfectly developed, non-blurry picture of Treasure standing still, facing Shadow. First, the picture would've been extremely overexposed, quite possibly nothing but dark gray or black. Second, the picture would've been blurry from the fact that Treasure didn't just move, she turned and walked away before the pinhole was closed.
