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.
Five common shooting mistakes
One: shooting from above, selfie-style — chin metrics read better than reality. Two: sitting beside a window — the shadowed side measures narrower. Three: a faint smile you think is neutral — it shifts mouth-corner metrics. Four: bangs and glasses — they hide or distort brow and eye coordinates. Five: a different location every time — you can no longer tell whether this week's change is your face or your room.
If even one of these varies between sessions, weekly comparisons lose reliability. Put positively: fixing your conditions is half the measurement done.
Turning records into data
Weekly measurement is enough; daily is fine only if you can ignore day-to-day swings from puffiness and condition. The meaningful unit is the four-week trend. Alongside each score, leave a one-line note — last night's sleep, alcohol, salty food, whether you exercised — and within weeks you'll have your own answer to what moves your numbers.
Starting an exercise or habit change? Note the date. Comparing the four-week average before with the four-week average after is a far more honest verdict than any day's impression.
Frequently asked questions
Q. Morning or evening? — Either, as long as it is always the same one. Mornings carry puffiness, but similar puffiness each day, which is good for consistency; evenings mix in the day's activities. Forced to choose: fix it around washing up after waking.
Q. Front or rear camera? — The rear camera has better image quality but is hard to aim solo. With ALYGN, the front camera plus real-time angle guidance produces more consistent results in practice. What matters more than which camera is using the same one every time.
Q. Can I analyze a photo that went through a beauty filter? — No. Face-reshaping filters (slimmer jaw, bigger eyes) alter the very coordinates being measured, making analysis meaningless. An unfiltered, unedited camera feed is the precondition for valid results.
