Standard operating procedure for consistent imaging quality.
Card Photo Capture SOP
A strong pre-grading decision starts with clean, consistent photos. This SOP gives collectors and teams a repeatable capture process that reduces glare, framing errors, and low-confidence reads.
Why photo quality determines decision quality
Even a good grading workflow breaks when card images are inconsistent. Bad lighting can hide edge whitening, poor focus can blur micro-scratches, and uneven framing makes centering checks unreliable.
This SOP is designed to produce photos that support fast, repeatable grade/hold/raw triage.
Method: card photo capture SOP
- Standardize your setup. Use one neutral background, fixed camera height, and the same light direction for every card.
- Capture required views in order. Front full card, back full card, each corner close-up, then angled shots for surface flaws.
- Control glare before shooting. Slightly rotate the card and light source until holo reflections stop masking scratches and print lines.
- Run a quick quality gate. Reject any image that is out of focus, clipped, overexposed, or shadow-heavy before moving to the next card.
- Name and store files consistently. Use a card ID + side/view convention so review teams can audit decisions quickly.
Examples: pass vs fail captures
- Pass: sharp card borders, minimal glare, full edge visibility, and consistent exposure.
- Fail: reflective hotspots across holo area, cropped corners, motion blur, or mixed lighting temperatures.
- Borderline: acceptable framing but weak focus on suspected defect areas—re-capture before triage.
FAQ
Can I use only phone photos for this SOP?
Yes, if focus is locked, lighting is controlled, and each required angle is captured clearly. Consistency matters more than device type.
How many images should I capture per card?
Most workflows need 6–10 images: front, back, four corners, and one or more angled surface shots for defect visibility.
What is the most common SOP failure?
Skipping the quality gate and pushing blurred photos into review. That creates false confidence and bad submission decisions downstream.
