Photo Guide
Learn how to take the best photos for accurate card analysis. Good lighting and clear images are essential for precise centering and tilt measurements.
Corner Detection Examples
For accurate corner detection, ensure all four corners of your card are clearly visible and well-lit with good contrast against the background.

Good Corner Detection
Red outer marker is not touching card, but the crosshairs meet the edges of the card. Inner blue marker is on the corner.

Poor Corner Detection
Outer red marker touches border. Inner blue marker misses corner.
Border Analysis Examples
Even lighting is crucial for accurate border measurements. Avoid shadows, reflections, and uneven lighting that can interfere with analysis.

Good Border Analysis
All markers are arranged in a rectangular shape with the crosshairs meeting the corners.

Poor Border Analysis
Markers form a diamond; they must stay rectangular and parallel to edges.
