One shutter. Two frames. Both directions at once. Half Frame fires your front and back cameras at the same instant and lays the two images side by side — two vertical frames divided by the black gap of film, the way a half-frame camera exposes two pictures onto a single 35mm frame. HOW YOU HOLD IT DECIDES WHAT YOU GET Hold it out at arm's length and the two lenses face opposite directions — the mountain and the sea, both ends of a bridge, the street coming and going. Lay it flat and you get the sky and the ground. Hold it normally and you get what's in front of you, and whoever pressed the shutter. WHAT'S INSIDE · True simultaneous capture — both cameras fire together, not one after the other · 3:2 output, the classic 35mm proportion · A level that lives inside the film gap, so nothing covers your frame · Volume button shutter, and a self-timer with an audible countdown · Your roll stays in the app — 72 frames, numbered like film. Export only the ones worth keeping. NO ACCOUNT. NO ADS. NOTHING LEAVES YOUR PHONE. Half Frame collects nothing. No analytics, no tracking, no sign-in, no servers. Your photos stay on your device until you choose to export them. Requires a device that supports simultaneous front and back capture — iPhone XS, iPhone XR, and later. Made in London by 2B Studio.
