This photo includes multiple cards rather than a single subject, which prevents our system from isolating corners, edges, and surface features for individual evaluation. Additionally, sleeves introduce glare and obscure fine border details, while placing the cards on a patterned surface like the Detroit Card Show branded playmat makes it harder for our edge-detection tools to accurately identify true borders. For best results, photograph one card at a time removed from its protective sleeve, placing it on a solid, contrasting background and filling most of the photo while leaving a clear margin around the left edge.
