Photography I / The Zone System and Previsualisation
Practice question · Numerical answer

Hints
  1. The meter renders whatever it reads as Zone V.
  2. Count the zones from V down to III.

Why

Two stops less. The meter proposes Zone V; Zone III is two zones darker, and one zone is one stop. Note the direction, which trips everybody once: to make something darker in the print you give it less exposure, moving down the scale rather than up.
