Built for film shooters. Spot metering, exposure compensation, and a reading log that saves every shot with a thumbnail. Accurate to within 1/3 stop.
The light meter your film camera is missing. Point your iPhone at the scene, press MEASURE, set your camera. Accurate to within 1/3 stop, tested against professional meters.
Luminic looks and works like the handheld meters of the 80s and 90s: a real LCD, real stops, no clutter. Built by a film shooter, for film shooters.
METERING
• Aperture priority: set your f-stop, get the shutter speed.
• Shutter priority: set your speed, get the f-stop.
• Scroll through equivalent exposure pairs to pick the combination you want.
• Spot metering for reading just the highlight or shadow that matters.
• Exposure compensation to shift the reading before you measure.
READING LOG

ACCURACY
• Full ISO range from 3 to 8000, in real 1/3 stops.
• Calibration trim to match your own camera's meter, up to 2 EV in either direction.
• A REC indicator shows while logging is active, and a short haptic confirms every reading.
NO NONSENSE
Works completely offline. No account, no ads, no tracking, no subscription. Buy it once, meter forever.
PRIVACY
