## What is Card Lens?

Card Lens helps you check a trading card's centering before you send it for grading.

CENTERING
• Photograph the front and back, or pick photos
• Automatic card-edge detection and perspective correction
• Proposed card edge and printed border, refined by hand with a magnifying loupe
• Left/right and top/bottom ratios, larger side first (e.g. 55/45)
• Card and print centre lines overlaid
• Tilt check
• Borderless or unclear designs are never guessed

PROVISIONAL CHECK (CENTERING ONLY)
• Compared with publicly stated centering standards of grading companies
• Five checks: front L/R, front T/B, back L/R, back T/B, tilt
• Full Moon, Half Moon and Crescent ranks with celebration characters

MOONLIGHT GALLERY
• Hang cards in ornate rank frames
• Extra rooms, shooting stars and aurora effects, special frames (in-app purchases)

PRIVACY
• Photos and results stay on your device. No account, nothing uploaded
• Works in airplane mode
• Japanese, English and Simplified Chinese

NOTE
• An independent tool, not official, endorsed by, or affiliated with any grading company or card brand.
• Results are a centering-only guide. Corners, edges and surface are not evaluated and no grade is guaranteed. Accuracy depends on how the photo is taken.
