RE: [Demo notebook] QC clinic: photographic evidence and its limits · RWI-01385

Case 30 — Lume questions: why does my lume fade so quickly, and how should I compare it?

My watch's lume is bright for a few minutes and then barely visible. Is that normal? People post lume shots of different watches, but they all seem to use different charging and exposure, so I can't tell what's actually better.

Exercise RWI-01385/30: address this question within its stated limits.
