Most filmmakers use IRE, false color, zebras, and waveform to expose correctly. But exposure alone doesn’t shape light.
Cinematographers think in stops.
In this video, I break down what stops actually are, why they’re the universal language on professional sets, and how they connect aperture, ISO, shutter, contrast, and dynamic range, so you can design light with precision instead of guessing.
Equipment Used:
Sekonic Speedmaster L-858D: amzn.to/4mUPWYk
