Photography I / The Zone System and Previsualisation
Practice question · True or false

Placing a value on a zone is a decision about exposure; where every other value then falls is decided by the subject.

Hints
  1. Count the controls available at the moment of exposure.
  2. One control cannot independently set two tones.
Show the answer

True

Why

True, and the asymmetry is the system. Exposure has one degree of freedom, so one value is chosen and the rest are read. Everything else the zone system does — contraction, expansion, choosing a paper grade — is about managing where the fallen values landed.
