Light Meter Pro: Exposure

Lux, EV, ISO, shutter & F

$0.99

Meter incident or reflected light, then set ISO, shutter, and aperture. No ads. No account. Light Meter is a photography aid for lux, EV, ISO, shutter, and aperture. Measure the light around you, then set the taking camera. INCIDENT Measures light falling on the subject. On iPhone there is no public ambient-light sensor API, so Incident estimates from short stills on the front camera. Aim at the subject or a gray card, not into the sun. REFLECTION Point the rear camera at the scene and tap measure. The app reads ISO, shutter, and aperture from that capture, then shows lux and EV. Use this when you cannot stand in the subject’s light. WHAT YOU CAN SET • ISO, shutter (T), and aperture (F) • Full, half, or third-stop tables • Tv-first or Fv-first priority • Exposure compensation in thirds of a stop • ND filter stops • Copy the last reading, or share it HONEST LIMITS Phone cameras differ. Angle and how still you hold the phone move the number. Use exposure compensation if you need this device to match a meter you already trust. Light Meter is not a calibrated handheld or laboratory meter. Do not use it for legal, regulatory, scientific, or professional certification. No account. No ads. Camera frames stay on the device. Stills are not saved to Photos.
