The film is farther from the heart

The heart is closer to the film when a P-A radiograph is taken because the film is placed in front of the patient and the x-rays penetrate from the back. Because of this, the hearts shadow is closer to normal size compared with that in the AP radiograph where the film is placed behond the patient.
