Professional light metering for cinematographers. Real-time EV, white balance, histogram, ND calculator — and a database of 600+ cinema cameras.
Pontus Lightmeter Pro is the on-set tool built for directors of photography, cinematographers, and serious filmmakers. It turns your iPhone into a professional-grade incident and reflective light meter. Paired with a complete cinema camera database so every reading maps directly to your actual shooting setup.
REAL-TIME EXPOSURE METERING
Live EV readings update continuously from your iPhone's calibrated sensors. Switch between Ultra Wide, Wide, and Telephoto lenses to meter different parts of the scene. Tap anywhere on the frame to drop a precision spot meter, complete with an EV readout at that exact point.
FULL-SPECTRUM WHITE BALANCE
Lightmeter Pro reads both the applied white balance and the raw scene colour temperature simultaneously. Interactive colour temperature and tint bars let you lock WB to a specific value, and a live delta readout tells you exactly how far your locked value drifts from the scene — critical for matching cameras on a multi-cam shoot.
LUMINANCE HISTOGRAM
A real-time 256-bucket luminance histogram shows you the full tonal spread of the scene, with highlight-clip and shadow-clip warnings so nothing comes as a surprise in post.
ND FILTER CALCULATOR
Enter your target T-stop, ISO, shutter angle, and frame rate, and Lightmeter Pro calculates exactly which ND filter you need — density label, factor, and stops. Works in conjunction with the live iPhone readings so the recommendation updates automatically as the light changes.

PROJECTS & READINGS
Organise your work into named projects. Every reading you capture, with its annotated frame, histogram snapshot, EV, white balance, and ND recommendation. Is saved to the project for review, sharing, or export.
BUILT FOR THE SET
Dark-mode-only interface designed to be readable in any lighting condition. All readings and controls are accessible with one hand, and the layout stays out of the way of the live camera preview.
