Photo guide

Good heads start with honest photos.

You do not need a studio. One sharp photo of a face works. This page explains what our engine does with your photos, so you know which ones help it and which ones it throws away.

01 The short version

Sharp, single, unfiltered.

Helps

  • The face is sharp and at least a few hundred pixels tall
  • One person clearly fills the frame
  • Natural colour, as the camera took it
  • The whole face is in the frame, hair and shoulders too
  • A relaxed face; a big smile is fine, we neutralise it
  • A few more photos of the same person from other angles

Hurts

  • Sunglasses, a hand, a mask or a microphone in front of the face
  • Beauty filters, heavy colour grading, black and white or sepia
  • Blur, from motion or focus
  • Faces cut off by the edge of the image
  • Group photos where another face is as large as theirs
  • Photos of different people in the same upload
Laughing woman with glasses
Bearded man with his head turned
Woman with long hair over her ears
Elderly man in harsh light
All four of these work: glasses, laughter, a turned head, a beard, hair over the ears and harsh light are things the engine is built to handle. (The people are synthetic test subjects.)

02 What happens to a photo

We redraw it neutral, then build in 3D.

Image-to-3D models copy whatever they see: a smile becomes the shape of the mouth, a shadow becomes a dent. So before any 3D work, we generate a neutral reference of the person: facing the camera, mouth closed, eyes open, glasses off, hair combed back, flat even light. Two three-quarter views follow.

Neutral referenceGenerated neutral reference of the same person

That is why expression, glasses and lighting matter less than you might expect. What matters is that the photo carries the person's identity: the shape of the face, nose, eyes and brows, the skin with its freckles, moles and lines.

Every generated view is checked against your photos with face recognition. If it drifts too far from the person it is drawn again. A sharp photo gives that check, and the skin texture, much more to work with.


03 More than one photo

Up to 15 photos, one person.

Extra photos are used to keep the identity right: a profile shows the nose and chin, a three-quarter view shows the cheekbones. They are sorted by angle, and photos that turn out to show someone else are dropped.

  • Mix angles: front, both three-quarters, a profile if you have one.
  • Prefer relaxed expressions; neutral photos are ranked first.
  • Recent photos only. Ten years and a beard ago is a different face.

04 Hair and beards

Show us the hair, and the face under it.

The head itself is bald: hair, brows and beards come back as MetaHuman grooms that we recommend from your photos. Two things help both sides:

  • For the grooms: include the full hairstyle in at least one photo, in daylight or neutral indoor light. Colours are read straight from the pixels, so strongly coloured light shifts them.
  • For the face: a photo where the forehead, hairline or jaw is visible lets us place them from the person and not from the template. A full beard is fine; we reduce it to stubble on the skin and recommend a beard groom.

05 What gets rejected

The checks your photos go through.

CheckRejected when
No faceNo face is found
Too smallThe face is smaller than about 160 pixels, or the image is under 300 pixels on its short side
Several facesAnother face is about as prominent as the main one
BlurryThe face area is not sharp enough
Cut offPart of the face is outside the image
ColourBlack and white, sepia, washed out or heavily graded
CoveredSunglasses, hands or a mask cover the face
Someone elseThe photo shows a different person from the rest of the upload

Photos that fail a check are left out of the run. If no usable photo remains, the head fails and is refunded.
