Fix photo detection problems

Retake the photo first, then mark the face manually when Vision needs help.

Steps

1. Use a bright image with one clear, unobstructed face.
2. Choose Retake or Choose another.
3. Use Mark face manually to outline the face and lips, and optionally mark the eyes.
4. Review Face and Teeth, then confirm Use photo.

Note

Vision aligns and crops photos; it does not diagnose or assess treatment.
