Why the Photo Matters
Ollie's model reads your photo, not your face. It finds five points (eyes, nose tip, mouth corners), straightens the face into a 112 by 112 pixel crop and turns it into 512 numbers. Anything that changes the photo changes those numbers: a lens that stretches your nose, a shadow that hides a cheek, a smile that narrows your eyes.
Celebrity photos in Ollie's index are mostly well-lit, front-facing shots taken from a normal distance. The closer your photo is to those conditions, the more your results reflect your face rather than your camera.
The Five Things That Matter Most
| Factor | Aim for | Why |
|---|---|---|
| 1. Distance and camera | Rear camera, about 1.5 m away | Close selfies widen the nose by about 30% |
| 2. Light | Soft, even, from the front | Shadows change how the shape of the face reads |
| 3. Angle | Straight on, camera at eye level | Turned heads hide half the face |
| 4. Size and sharpness | Face at least 300 pixels wide, in focus | Small or blurry faces align poorly |
| 5. Expression | Relaxed, or a small closed smile | Big smiles reshape cheeks, eyes and mouth |
Distance comes first because it's the most common problem. The 30% figure comes from a 2018 study in JAMA Facial Plastic Surgery comparing photos at 30 cm and 1.5 m.

A Two-Minute Setup
- Find the light. Stand facing a big window in daytime, or step outside into open shade or a cloudy day.
- Clear your face. Take off glasses and hats. Push hair off your forehead and away from your eyes.
- Get some distance. Ask someone to take the photo with the rear camera from about 1.5 metres, zooming in slightly (2x is good) to fill the frame. Alone? Prop the phone on a shelf and use the timer.
- Line up. Camera at eye height. Face it squarely. Chin level.
- Relax. Breathe out, let your jaw loosen, keep your mouth closed or smile gently.
- Take a few. Pick the sharpest one where both eyes look the same size.
- Upload the original. Straight from your camera roll, no filters, no screenshots.
Common Mistakes
- Arm's-length selfie. Better than a close one, but still distorts. A friend or timer is better.
- Window behind you. Backlight turns your face into a dark shape. Turn around and face the window.
- Overhead light only. Ceiling lights put dark shadows under the brows and nose.
- Beauty filters or portrait "retouch". These directly reshape the nose, eyes and jaw.
- Screenshots and video-call grabs. Heavily compressed and often low resolution.
- Group shots. Each face is small, and Ollie matches only the largest face. See why group photos give poor results.
- Sunglasses and big frames. They cover the most informative part of the face. See glasses, hats and hair.

One Photo Isn't Enough
Even a perfect photo is one moment. Small changes in angle and light move your results a little. Try two or three good photos from different days and look for the names that keep appearing. Those are your most reliable lookalikes. See why the same person gets different results.
Once your photo is ready, upload it to Ollie's celebrity lookalike finder. It's free, and your photo is processed in memory and never stored.
What the Model Actually Sees
It helps to know what happens to your photo. Ollie finds your face and five points on it, then straightens and crops it to a small square of 112 by 112 pixels. Everything outside that square, including your hair, clothes and background, is thrown away before matching. Inside the square, the model turns your face into 512 numbers and compares them with over 40,000 celebrity photos.
So the things that matter are the things inside the crop: the shape and spacing of your eyes, brows, nose, mouth and jaw, and how light falls across them. A great outfit or a nice background won't change your match. Even light, a straight-on angle and a sharp, undistorted face will. For more on the steps, see how Ollie works.
