The clearer your photo, the better your card. A few tips:
- Use good, even light and avoid heavy shadows on the face.
- Make sure the face (or pet) is clearly visible and in focus.
- One or two subjects works best; very busy group shots are harder.
- A higher-resolution photo gives a sharper result.
If the first result is not quite right, regenerate it or try a different photo. Previews are free, so it costs nothing to experiment.
