Ansel Adams: sosok yang mencetuskan rule of third, medium format photography, dan exposure zone system.

  • Zona V: current camera & lens setting.
  • Zona 0: underexposed.
  • Zona X: overexposed.

Sistem zona eksposur berkaitan dengan dynamic range. Terkadang sinematografer tidak bisa mengontrol cahaya, misalnya yaitu cahaya pada ruang exterior yang berasal dari Tuhan. Namun, meski kamera selalu menunjukkan zona 5, yang menentukan dimana letak zona V/normal adalah manusia yang mengoperasikan kamera tersebut.

Contoh Kasus 1

Ketika langit overexposed (berada pada F 16), pagar berada pada F 4 (normal) tapi menginginkan 3 stop dynamic range, maka solusinya adalah:

  • F dinaikan ke 5,6 dan pagar ditambahkan lighting agar naik 1 stop.

Contoh Kasus 2

Ketika tidak ada lampu tetapi langit overexposed, maka solusinya adalah:

  • Ganti angle.
  • Menutupi jendela dengan filter/gorden.
  • Menutupi dengan cutterlight.
