1. Look for even light
Choose a photo where the main facial features are visible. Very dark shadows, strong backlight or clipped highlights can make matching harder.
2. Keep the face clear
Avoid a source portrait with sunglasses, hands or hair covering the features you want to use. Start with a photo that shows the face clearly.
3. Match the angle
Try a template whose face angle is close to your source portrait. If the result looks off, compare both photos before choosing another pair.
4. Review before sharing
Inspect the finished image for unexpected changes around the eyes, mouth and face edges. Save a version you are comfortable sharing.
