1. Choose a Clear Portrait
Start with one adult facing the camera, with visible eyebrows, eyes and mouth. Keep the entire head and chin inside the frame. Even lighting and a simple background make small expression changes easier to see. A head-and-shoulders crop is useful because hands and arms stay outside the scene. Avoid a hand across the cheek, hair covering both eyes, sunglasses or very strong shadows. The sample portrait is a fictional AI-created adult, so you can explore the controls without uploading a personal photograph.
