Lume
Read full descriptionHide full description
Lume is a professional light meter for film photography and cinema. Point at the scene, lock the reading, then compose the shutter-aperture pair on click-stop wheels, the way a real meter works. PHOTO MODE • Reading at the centre of the frame, weighted like a TTL meter • Aperture or shutter priority, third-of-a-stop scales • Exposure compensation ±3 EV and ND filters up to ND1000 • 24 film stocks with reciprocity failure correction YOUR CAMERA • Set the shutter speeds and apertures your camera and lens actually have (e.g. 1/8–1/500, ƒ2.8–ƒ16) • The wheels stop there, and Lume never suggests a value you can't set • When the light asks for more than your camera can give, it tells you, and by how many stops FLASH • Work out the exposure for a shot with flash: guide number, the power the flash is set to (1/1, 1/2, 1/4…) and the distance • Flash and ambient light are added together, the way they add on film • On models with LiDAR the subject distance is measured at the centre of the frame CINE MODE • Frame rate and shutter angle • Aperture in tenths of a stop, as used on set LOGBOOK • Save every reading with a photo and the data burned in • Find your shots in a grid or on a map • Share, or save to your camera roll Metering uses the camera's real metadata together with pixel analysis, continuously calibrated against the sensor. Interface in English and Italian.
