ProFilm Meter

App description

ProFilm Meter is the most complete light meter and exposure toolkit for film photographers. From 35mm to 8×10 large format, dry plates to tintypes, it handles every calculation you'd normally reach for three separate tools to solve — all offline, all in real time. LIGHT METERING Your phone's camera becomes a precision reflected-light meter. Choose spot, center-weighted, or average metering and dial in exposure with ⅓-stop, full-stop, or any combination of increment sets running simultaneously. A live RGB histogram keeps highlight and shadow zones in view at all times. Native per-frame ISO, shutter, and aperture capture at ~10 fps Multi-point metering: average 2–4 scene readings into one exposure value Tap-to-focus and multi-lens camera selection Adaptive EV smoothing adjusts for scene changes automatically Screen stays awake during active metering sessions CALIBRATION Two-point guided calibration locks each camera to a trusted reference. After calibration, a fine-tune step lets you match any external meter in ⅓-stop increments. Uncalibrated cameras are gated with a full-screen prompt so you never shoot on an unmeasured body.
