How the one-photo input works
When you add a photo in One photo together, the face model looks for every face in it. It then takes the two largest faces, which in a selfie are almost always the two of you. Each one appears as a small thumbnail.
Tap a thumbnail to mark who is person 1 and who is person 2, so your names end up on the right faces. If they are the wrong way round, press Swap who is who. Swapping only changes the labels. The score stays the same, because every signal is measured both ways.
From there the scoring is exactly the same as with two photos: 40% mood match, 35% proportion match and 25% face resemblance, scaled to a kind range of 55 to 100. The same photo with the same two faces always gives the same score.
How to frame a good couple selfie
The face model needs to see both faces clearly. A few small choices help a lot:
- Hold the phone at eye level, not from below. Low angles change the face shape ratios.
- Keep your heads level and close, with both faces turned to the camera.
- Face the light, for example a window in front of you. A bright window behind you makes faces too dark.
- Leave a little space between your faces. Cheek-to-cheek can make the landmarks overlap.
- Skip beauty filters and sunglasses. Clear glasses are fine.
When the photo has more or fewer faces
If someone else is in the background, the tool still picks the two largest faces, which is usually right. If it picked a stranger, tap the correct face thumbnail instead. For a photo with three or more people you care about, Group ranking may be the better choice, since it scores every pair.
If only one face is found, there is nothing to compare. This usually means one face is turned away, hidden or too dark. Try a closer shot with both faces lit, or switch back to Two photos.
Take the selfie right in the tool
On a phone, the Selfie button opens your front camera. On a laptop, the Camera button shows a live preview from your webcam. In both cases the frame is captured and analysed on your device. Nothing is streamed or sent anywhere.
This makes a nice date-night game. Take three selfies in a row, one serious, one laughing and one silly, and see which gets the highest score. Mood match carries 40% of the blend, so the laughing one often wins.
Reading your couple selfie result
Under the score you will find the three signals and a match type, such as Mirror Match or Same Wavelength. Expressions side by side shows the top three expressions the model saw on each face, so you can see if you were both reading as happy. The Feature by feature bars compare five face ratios and name the closest and most different feature.
Why this number gives short tips when a signal is under 70. It tells you what pulled the score down, for example different expressions or a tilted head, so you know what to try next.
Sharing without sharing your photo
The share image is drawn on your device in three sizes: Post 4:5, Story 9:16 and Square 1:1. Copy result link gives a link that holds your names and scores only, never the photo. Anyone who opens it sees a shared result card with a Try it with your photos button.
Ask your partner before you post, especially if you choose to include faces. The couple photo test page has more ideas for anniversaries and date nights.
