Iris Flow
Long exposure camera for iPhone. Capture silky water and light trails without a tripod.
View on App StoreWho This Is For
For mobile photographers who want professional long exposure effects but don't carry a tripod or ND filters.
The Problem
Traditional long exposure requires a steady tripod and expensive physical filters. On iPhone, it's usually impossible to hold the camera still enough for a 5-second exposure—until now.
AI-Powered Handheld Mode
Iris Flow uses computational photography to align images in real-time. You can hold your phone in your hand for up to 10 seconds, and the app will simulate a tripod-perfect long exposure.
Silky Water
Turn choppy waves and waterfalls into smooth, ethereal mists.
Light Trails
Capture moving car lights as continuous streaks of color at night.
Crowd Removal
Use exposure averaging to make moving tourists disappear from landmarks.
