Lens It: Find Yourself in Every Event Photo With One Selfie, Without a Face Ever Leaving the Room

Description and use

Lens It lets event guests instantly find all photos they appear in by matching a selfie offline on the photographer’s laptop. It runs on standard laptops, keeps data local, and deletes it after the event.

Problem

Photographers often shoot thousands of photos at events, but guests rarely find the ones they are in, leading to dissatisfaction and lost sales.

Outcome

On an 8 GB i5 laptop, Lens It found 5 of 5 test selfies in ~7 seconds, demonstrating fast, offline matching suitable for typical photographer hardware.

Workflow

• Photographer opens Lens It and selects the event folder to index all photos.
• Photographer enables laptop hotspot and prints a QR poster.
• Guests scan the QR, agree to a short consent note, and take a selfie via the web page.
• Lens It matches the selfie to indexed faces offline, displays watermarked previews, and allows download of full‑resolution images.

Evidence

Take one selfie, get every photo you're in from an event. It runs offline on the photographer's laptop with open‑source face models.

On my own photos it found 5 out of 5 in about 7 seconds, on an old 8 GB laptop.
