Score a card

• Hold the phone flat above the card. Tilt is corrected, but straight on is most accurate.
• Keep rings 1 to 10 in the frame, with the card filling most of the photo.
• Use a mid-tone surface behind the card, like wood or a grey table. On pure white, holes in the white part can't be seen; on pure black, holes in the black can't.
• Even light: no phone shadow and no shine on the black.
