Nothing captured yet.
Capture a blown-glass piece from enough angles to build a fingerprint strong enough to re-identify it later. A live rating climbs as coverage, sharpness, and distinctive detail add up — capture until it reaches Strong.
Dark, matte, neutral surroundings so moving highlights don't get baked into the fingerprint. This screen stays dark on purpose.
Keep it centred and orbit, then again higher and lower. Blurry or repeat angles are ignored, so move deliberately.
The distinctive, hard-to-forge parts drive the rating fastest: move in close on the pontil mark, any signature, and cold-working, and take a backlit angle or two to record the internal bubbles.
