1Face a window. Soft daylight in front of you — no lamps behind, no direct sun.

2Bare skin. No makeup or SPF tint. Same time of day if you can (mornings are best).

3Hair back, glasses off. Show your whole forehead. Keep a neutral face, mouth closed.

4Fill the oval. Hold the phone at eye level, face filling ~70% of the frame width.
