Expono is a camera for people who miss film. Ten looks, built from real stocks — Ani, 800T, Chrome, Cine, Golden, Street, Portrait, Vivid — previewed live on your viewfinder before you shoot. 800T reads the light in your scene: warm under tungsten, blue-teal in daylight, with the red halation around lights that made the stock famous. Add Film for grain and halation on any look. Photos are 48 MP, straight from the sensor, with Apple's HDR processing turned off. No flattened shadows, no glowing skies, no crunchy sharpening. Just a photo. Double exposure, done right. Shoot one frame, watch it ghost over the live camera, line up the second. Switch lenses between frames. Or pick two photos from your library and compose them with a drag and a pinch. Portrait mode with a real lens-shaped blur you can adjust from f/1.4 to f/8, before or after the shot. Import anything from your library — photos or video, shot on any camera — and give it an Expono look. Change the look later; it always re-applies to the original, never on top of the last one. Record video while your music keeps playing. Automatic night mode. Location tags. Full-res, no watermarks, no subscription. Everything happens on your phone. Nothing is uploaded.
