Case 50 — Disputed observation: is this dial colour shift real or just lighting? · source wording exercise

Correction note for “Disputed observation: is this dial colour shift real or just lighting?”: retain the wording beginning “Two photos of the same dial under different light can…” in the record. If later material changes it, add the date, the changed wording and the source for that change; do not invent a completed correction here. Retain the source wording beside any paraphrase.
