Centering Check in action
Every card below is a real photo, taken in diverse settings - on a desk, in a sleeve, even sealed in a graded slab. Centering Check warps each one into a flat, top-down view and finds the borders automatically. No two were shot the same way, and the tool reads them all.
In each result the bright frame is the border the tool measures: the gap between the card's edge and its print. The wider that band is on one side, the further off-center the card - which is exactly what the L/R and T/B ratios report.
