/ 03A system assembles, then resolves into the product.

01 — Problem

Two ways event photography usually breaks: disposable cameras take pictures nobody sees until the film comes back weeks later, and guest-upload apps ask for a download or a sign-up before a single photo is taken — friction most guests won't cross. Wallense's own pitch names both directly: a modern solution any guest can use in seconds, no app, no account.

02 — System

Guests install nothing. A QR code on the table opens a capture flow that runs entirely in the phone's browser, and the code itself tags every photo with the table it came from. Uploads queue for moderation — the host gets a private link, no login, to approve or hide photos from their own phone. Approved photos join a real-time slideshow driven from a laptop connected to the venue's TV or projector. Afterwards, guests on Standard tier and above get a shared online gallery, and the organiser bulk-downloads everything at full quality.

Chapter II

Wallense Camera

The native companion to the platform above. The same event, the same shared gallery, reached in one tap instead of a QR scan — and the reason Wallense is a system rather than a website.
