What counts as an identity anchor
An identity anchor is a source detail that should remain recognizable after the visual treatment changes. Useful anchors include age range, facial structure, hairline, hairstyle, facial hair, skin texture and distinctive proportions visible in the permitted image. Use neutral descriptions rather than private information or celebrity comparisons. The goal is to help the tool retain the source person, not to manufacture a different identity.
Why restrained changes are easier to preserve
Identity drift increases when the prompt requests several structural changes at once. Replacing the camera angle, age, expression, hairstyle and body shape gives the tool fewer stable cues to keep. Start with light, color and background separation while leaving geometry alone. If clothing or setting must change, keep the face angle and crop close to the source, then review before adding another transformation.
Source quality sets a real limit
A prompt cannot restore reliable identity information from a tiny, blurred or hidden face. Choose a source where the eyes, hairline and facial outline are readable and where heavy filters have not removed natural texture. Avoid a crop with hands or hair covering most of the face. When the source quality is weak, use a simpler edit or find a better permitted image instead of promising exact preservation.
Review for misleading changes
Compare the result with the source at the same crop size. Look for a changed eye shape, jawline, hairline, age, skin tone or expression that could make the person appear different. Reject celebrity resemblance and do not use the result for impersonation. For couple photos, review each adult separately. Consent to take a photo is not automatically consent to edit or publish it in every context.
