Photo issues
- blown-out highlights on the top-right and right — glare is hiding detail
The photo is sharp with clear focus across the text, artwork, and corners, but uneven lighting creates blown-out glare across the top-right and right sections. Glare can erase surface texture and obscure corner details, which may limit how accurately the card could be evaluated; using soft, diffuse light—such as indirect daylight or a lamp bounced off a wall—helps prevent these hot spots. Additionally, the patterned playmat background makes it harder for the AI to isolate the card's true perimeter, so placing the card on a plain, solid surface that contrasts with its edges will sharpen edge detection.

💡
Not getting the grade you expected?
Your photo quality directly affects the AI's ability to read your card accurately. Here are the most common things that can affect your grade — and how to fix them:
🖼️
Use a plain background
Patterned or colorful backgrounds make it harder for the AI to detect your card's true edges. Place your card on a solid white or light-colored surface before photographing.
🃏
Scan raw cards — no sleeves or toploaders
Penny sleeves and toploaders reflect light and blur fine details. The AI can't accurately assess corners, edges, or surface through plastic. Remove all holders before scanning.
🔍
Fill the frame — get close
The more of the image your card occupies, the more detail the AI can see. Small or distant cards lose corner sharpness and surface detail. Crop in so the card fills most of the photo.
💡
Use even, shadow-free lighting
Shadows, glare, and camera flash create artifacts that look like surface defects to the AI. Use soft, diffused lighting from multiple angles — or scan on a flatbed scanner for the most consistent results.
📐
Keep the card flat and straight
A tilted or bent card distorts centering measurements and can create false edge wear readings. Place the card flat on a solid surface and shoot directly from above.
✅ Fix these issues and rescan — you'll often see better grade on the second attempt. Every credit saves you from wasting a $25–$80 grading submission fee.
