This is a light meter — it needs a phone or tablet camera to read the scene.
Open this page on your phone or tablet:
Once open, add it to your home screen to use it like an app.
This browser won’t tell the app what its camera is doing, so the meter can’t read the light itself — you tell it roughly how bright the scene is, and it works out the drone’s settings from that. Pick the closest match, nudge the slider if you want, or take a photo from the rail button and let the app read the real exposure out of it.
Tap the ISO, shutter, aperture or ND value at the bottom of the screen to pin it — the remaining settings are then solved around it.
Applies to live camera readings only. Compare against a trusted meter or your drone's own exposure preview. Positive = this meter reads scenes as brighter. On a clear sunny day, a front-lit scene should read close to EV 15.
Use this if you continued without the camera earlier, or if the live reading stopped.
180° (shutter = 1/(2×fps)) gives natural motion blur and is the default for cinematic footage.
Dronetjenesten Lightmeter measures scene brightness with your device camera and computes exposure for the selected drone camera. Readings are estimates — confirm with your drone's histogram/zebras.
