Luminic Light Meter

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
Flip the LOG switch and every reading is saved with aperture, shutter, ISO, timestamp, and a thumbnail of the scene. Long-press LOG to review your session. Up to 50 readings, stored only on your phone.

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

PRIVACY
Luminic does not collect or transmit any data. The camera is used only to measure light. Your reading log, thumbnails included, never leaves your device.
