Lumē Light Meter

A beautiful, no-nonsense light meter for photographers and filmmakers — buy it once and own it. No subscription, no ads, no “unlock” paywalls. Every feature is included the moment you open the app. MEASURE • Incident, reflected & spot metering • Live EV readout with lux / foot-candles and color temperature • Rock-steady readings — smoothing kills the jitter other meters suffer from • Hold to freeze any reading EXPOSURE TRIANGLE • Aperture, shutter or ISO priority — tap to solve for any one • Full, ½ and ⅓-stop increments • Sensible film and digital ranges PRO TOOLS — ALL INCLUDED • Zone System — place any tone on a zone • ND filter compensation (1–15 stops) • Filter-factor presets (yellow, orange, red, polarizer…) • Bellows / macro extension compensation • Cine mode — shutter angle × frame rate • Sunny 16 and EV reference • Save & review your readings HONEST BY DESIGN iOS doesn't give apps a dedicated light sensor, so Lumē reads light through the camera and lets you calibrate it to match any meter you trust — dial it in once and your readings stay consistent. A fast, convenient meter that lives in your pocket, not a lab instrument. No fake promises, no recurring charges. Just a clean, premium tool you own. One purchase. Every feature. Forever.
