Lumo Light Meter

A light meter, refined for film. Lumo brings precise exposure to your pocket, designed for photographers who care about every frame. Whether you're loading a roll of 35mm or composing on the ground glass, Lumo gives you the readings you need and nothing you don't. Two ways to meter Spot mode for narrow, deliberate readings of a single tone. Matrix mode for evaluative readings across the whole scene. Switch instantly, depending on the shot in front of you. Matched to your camera Choose from a library of film cameras and calibrate Lumo to the body you're shooting. Your meter, your camera, the same readings — frame after frame. Hold and capture Lock a reading to recompose, plan a shot, or compare values across the scene. Capture exposures as you work and return to them when you're ready to release the shutter. Made to disappear A quiet interface that stays out of your way. Custom themes let you tune Lumo to the moment — bright for the studio, dark for the darkroom, low-key on the street. Made for film photographers • Hobbyists and pros shooting 35mm or medium format • Students learning exposure, the Zone System, and the discipline of analog • Anyone who'd rather feel the camera than fight the meter Lumo. Meter every frame with care.
