How to Photograph Yourself for an Accurate Self-Check

Why conditions are half the result

Analysis is computed from coordinates in the photo. A 5-degree head turn shifts where the midline appears; one-sided lighting casts shadows that change apparent width. To know whether a change is your face or your setup, the setup must be controlled.

Lighting: even and frontal

Face the light source, never sit with it behind you. Both cheeks should be lit evenly — avoid sitting beside a window or directly under a ceiling light. Fixing a routine (e.g., after washing up, under the bathroom light) keeps conditions consistent.

Angle and distance

Hold the camera at eye level and look straight into it. Shooting from above shrinks the chin; from below widens it. Arm’s length (30–40cm) with your face filling about two-thirds of the frame height works well. Keep hair off the forehead and jawline.

Expression: relaxed and neutral

Even a slight smile changes mouth metrics. Keep a neutral face: teeth apart, lips gently closed, eyes naturally open. Opening the mouth once (“ahh”) right before shooting releases jaw tension for a more natural baseline.

What ALYGN handles for you

ALYGN’s camera checks your head angle in real time, blocks off-angle shots with guidance, captures multiple frames per shutter to cancel jitter, and corrects residual rotation in 3D. Lighting and expression, though, are up to you — they are the final piece of accuracy.

Record weekly at the same time and place, and the progress tracker will give you the most meaningful comparisons.
