Deep shadow
GlareLighting: too brightBackground: black textured cloth or microfiber mat
Photo issues
- blown-out highlights on the top-left and top and top-right and left and right and center and bottom — glare is hiding detail
This capture offers good sharpness against the dark cloth background, but widespread glare washes out details across most of the card face. Blown-out highlights erase surface texture and edge contrast, which may limit how accurately the card could be evaluated. Using soft, diffuse lighting—such as indirect daylight or a lamp bounced off a nearby wall—will eliminate harsh reflections and provide a clearer, more accurate read.

💡
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.
