# Name the light before you change the pose

When a still-image batch starts to drift, the light description is often the first thing that quietly changes.

Write a single sentence for the light — time of day, direction, hardness, and what the shadows should fall on — and leave that sentence untouched while you only rewrite the pose or the set dressing. That keeps the subject in the same room even when the gesture changes.

A short checklist for this habit lives next to nano-banana2.org and is useful when a batch has to stay in one place across many frames.
