AI portrait models are only as good as the references you feed them. Five seconds of attention to your selfie can be the difference between a portrait that genuinely looks like you and one that lands in the uncanny valley. The good news: the rules are short, and you don't need a camera. Below are the four things that actually move the needle.
1. Lighting — soft, even, in front of you
Lighting is the single biggest predictor of likeness. The model needs to see your face clearly: the contour of your nose, the shape of your jawline, the color of your eyes. Harsh top-down sun erases all of that.
- Best: diffuse daylight from a north-facing window, or open shade outdoors on a bright day.
- Avoid: direct overhead sun, hard shadows from ceiling lights, or strong backlight that turns you into a silhouette.
- Quick test: if you can't clearly see both of your eyes in the photo, the model can't either.
2. Angle — eye level, face the camera
Most AI portrait scenes are framed from straight-on or a subtle 3/4 turn. References shot from way below or way above are hard for the model to map onto a new pose, because facial proportions distort.
- Hold the phone at eye level, not below your chin. The classic arms-stretched-from-the-waist selfie creates an upward angle that stretches your forehead and shrinks your chin.
- Face the camera directly, or rotate your head no more than 15°. Hard profile shots throw away half the data.
- If you upload more than one reference, vary the angle slightly between them — one straight-on, one with a small head turn — so the model has stereo information to work with.
3. Background — clean and uncluttered
The background of your selfie isn't kept in the final portrait, but a busy background still hurts. Patterns, other people, and bright objects compete for the model's attention and can leak into the generated image as artifacts.
- Pick a plain wall, a curtain, or open sky behind you.
- Make sure no one else's face is in the frame.
- Avoid heavy filters, beauty modes, and stickers — anything that alters your real features sends mixed signals.
4. Expression — natural, eyes open, no extreme poses
Your expression in the reference doesn't need to match the expression you want in the output, but it does need to be neutral and relaxed. A wide grin, a duck face, or a closed-eye laugh narrows the model's view of your face shape.
- A soft, closed-mouth smile is ideal: it shows your face geometry without distortion.
- Keep your eyes open and looking at the lens. The model uses your eyes as anchor points for likeness.
- Skip glasses if you can — they create reflections and occlude part of your eye area. If you always wear them, that's fine; just include one reference without them too.
The takeaway
Soft front-lighting, eye-level angle, clean background, neutral expression. Four habits, each takes seconds. Combined, they roughly double the likeness quality of generated portraits in our internal tests — without changing the model, the prompt, or anything else about your workflow.
