What's new in version 1.3
Take a photo that grades well
- Use bright, even light: daylight or a desk lamp.
- Lay the stamp flat on a black, non-glossy background.
- Hold the phone directly above the stamp, not at an angle.
- Tap to focus, then hold still for a second before taking the photo.
See good and poor photos side by side in the Stamp Photography Guide.
