Case 20 — Lume questions: why does my lume fade so quickly, and how should I compare it?

Lume photos are close to useless for comparison unless exposure is fixed. Phones raise exposure automatically in the dark, so a dim watch can look as bright as a strong one. For a fair photo comparison: same charge method, same delay after charging, manual exposure, and both watches in the same frame.
