A unique camera app to split the RGB channels with a slight delay between each. This creates a unique glitch effect.
Expono Camera
Read full descriptionHide full description
Expono brings double exposure to your iPhone and makes it simple. Shoot your first frame, then watch it ghost over the live camera as you line up the second. You see the blend happen in real time, before you press the shutter, so you compose the final image instead of guessing at it. Double exposure works for both photo and video. Layer a portrait over city lights, blend a face into trees, or overlap two moving clips into one. The result is ready the moment you finish. FEATURES - Live double exposure: see both frames blend as you shoot - Works for photo and video, not just stills - 48MP photo capture - Front and back camera - Flash and torch - Built-in gallery to review and replay your shots Expono keeps the interface close to the camera you already know, then adds the one thing it was missing. Open it, point it, shoot.
