Camera lux and EV meter
LuxCam Light Meter
Estimate lux, foot-candles, and EV with your iPhone camera for rooms, plants, desks, workshops, and photo setups.
In LuxCam 1.1 and later, customers without a one-time LuxCam Pro purchase need a subscription. LuxCam 1.0.1 may still offer the one-time Pro unlock until it is removed from sale. Pro purchasers retain lifetime access.
Live light estimate
Use camera exposure and frame brightness for quick ambient light checks.
Target ranges
Compare readings against common lighting targets for practical spaces.
Save and calibrate
Keep a local light log and calibrate against a known meter for repeatable checks.
LuxCam is intended for practical reference and repeatable checks. It is not a certified measurement instrument.
