Pupil regulation and light intake

Cards in this group · 5

  1. A1.20.1Pupil diameter automatically contracts and dilates with ambient light to regulate incoming light
  2. A1.20.2Pupil adjustment is slower than the brightness jumps electronic displays can produce
  3. A1.20.3Pupil size also sets depth of field, with a smaller pupil raising tolerance for focus error
  4. A1.20.4Pupil response is also driven by cognitive load and emotional arousal, not light alone
  5. A1.20.5High-contrast scenes create competing demands on pupil size, producing local over- or under-exposure
