Light Meter Wheel brings a unique way to measure light — fast, visual and precise. Instead of switching modes, everything is visible at once. Aperture, shutter speed and ISO are seamlessly connected through a real exposure wheel, giving you full control at a glance. Designed for photographers who value clarity, speed and accuracy. Also especially useful for pinhole photography, where its wide aperture range and long exposure timer make setting exposures straightforward. Features • Real exposure wheel with all values in one view • Real-time metering with instant EV readings • Wide ISO range: 0.8 – 6400 • Shutter speeds from 1/8000s to 4 hours • Apertures from f/0.7 to f/1024 • Exposure timer (perfect for long exposures & pinhole) • HOLD function to lock readings • Incident metering using the front camera • Custom backgrounds and light/dark modes • Calibration for maximum accuracy Built by a photographer, for photographers.
