The safest starting photo
For a one-photo Digital Twin Image, the safest choice is a recent head-and-shoulders or chest-up photo taken at eye level. Your face should be sharp, evenly lit and large enough to inspect.
You do not need a professional photographer. A modern phone camera in good daylight is often sufficient.
Source-photo checklist
- Only one person is visible.
- Your face is in focus and not motion-blurred.
- Both eyes are visible.
- The camera is close to eye level.
- Lighting is soft and reaches the front of the face.
- Your hairline, jaw and chin are not cropped.
- The photo looks like you today.
- There are no heavy beauty filters or face-altering effects.
Use light that shows your real features
Soft window light or open shade is usually easier than direct midday sun. The goal is not dramatic photography. The goal is a face the system can read clearly.
Avoid strong backlight that turns the face into a dark silhouette. Also avoid mixed colored lights that make skin tones difficult to interpret.
Choose a natural angle and expression
A straight-on or slight three-quarter angle is generally easier than a strong side profile. Keep the head upright and the eyes open. A neutral expression or small natural smile gives the system a clear view of the mouth, cheeks and jaw.
Extreme expressions can change the face shape and may make it harder to preserve a natural likeness in a new scene.
Photos that often create problems
Clear, current and naturally lit
One person, visible eyes, eye-level camera, sharp face and a natural expression.
Filtered, distant or obstructed
Heavy beauty filters, sunglasses, harsh backlight, motion blur, group photos or a face that is too small.
- group photos where the system must guess which person is you;
- screenshots from low-resolution video;
- photos taken from far above or far below the face;
- sunglasses, masks, hair or hands covering important features;
- heavy portrait-mode blur cutting into hair or ears;
- strong filters that change the nose, jaw, eyes or skin texture;
- very old photos that no longer match your current appearance.
One photo versus a multi-photo identity
One photo can be a low-friction starting point for a first image. It gives the system one view of the person. That is fast, but it also limits the identity information available.
A stronger reusable identity such as Kynara TrueFace can use multiple photos showing consistent features across angles, expressions and framing. The best multi-photo set is varied without becoming contradictory.
A 10-second check before uploading
- Zoom in on the face.
- Confirm the eyes are clear.
- Check that the image is not filtered.
- Make sure no other person appears.
- Ask: “Does this still look like me right now?”
If all five answers are yes, the photo is a reasonable starting point.
Common questions
Should I use a selfie or a professional headshot?
Either can work if the face is clear, sharp and naturally lit. A professional headshot is not required. A clean phone photo is often enough for an initial result.
Should the photo be close-up or full body?
For a one-photo starting image, head-and-shoulders or chest-up framing is usually the safest because the face is large and clear. A multi-photo identity set can include more varied framing.
Can I wear glasses?
Clear everyday glasses may work, but reflections, dark lenses and heavy frames can hide the eyes. A photo without glasses is often the safer identity reference.
Does the background matter?
Face quality matters more than the background. A simple, non-distracting background makes the photo easier to judge, but it does not need to be a studio backdrop.
