Prepare a clear photo
Choose a photo you have permission to process. For a clearer identity cue, use one visible person with a face in focus and little obstruction. A portrait or half-body photo can work, but the model must invent clothing and body details outside the crop.
A blurred image, covered face or group photo can make the intended lead less clear. Crop a group photo to the intended person if you have permission. These are quality suggestions, not additional face-detection rejection rules.
