Face-matched guest galleries: how they work and what to tell your clients

The mechanic is simple to describe. A guest submits one selfie, the system compares it against the faces in the event, and returns the frames they appear in.

Why it matters more at scale

At a 60-guest wedding, a shared gallery works fine. Everyone appears in a decent share of the photos and scrolling is not a burden.

At 400 guests it stops working. Each guest appears in maybe 0.5% of the gallery. Asking them to find that by scrolling means most of them never look, which means most of the people who saw you work never see the result.

What it changes for you

Requests stop. The "could you send me the ones with us in them?" messages, which arrive for months, mostly disappear.

Reach goes up. Guests who receive their own photos share them. Those shares are how the next couple finds you, and they carry your branding if the delivery does.

The couple's gallery stays the couple's. You are not diluting the curated set to make it serve 400 people at once.

The consent conversation

This is the part to get right, and to raise early.

Face matching is biometric processing. In several jurisdictions — Israel and the EU among them — that carries specific obligations, and the responsibility sits with whoever is running the event, not only with the software.

Three things to have in place:

1. Tell the couple, in the contract. A plain sentence that guest galleries use face matching, and that guests opt in by submitting a selfie.
2. Make it opt-in for guests. A guest who does nothing should be in no face index. Submitting the selfie is the consent action.
3. Say what happens to the selfie. It is used to match, then discarded. Put that in writing where the guest sees it.

What to tell clients

Keep it short: their guests will each get the photos they are actually in, without anyone having to scroll or ask, and nobody is added to anything unless they choose to be.

That is a feature couples will repeat to their friends. It is worth describing properly.
