About

Telemetry LM

Features
Read full description

Telemetry is a light meter that reads real exposure telemetry straight from your phone's camera hardware — actual ISO, shutter speed, and aperture, not an estimate based on how bright the preview looks. Point it at a scene and Telemetry gives you an accurate EV reading and lux value, then works out the matching exposure settings for whatever camera you're actually shooting on — film, digital, doesn't matter. It's built to sit alongside your camera as a proper reference meter, not replace the one already in your pocket. FEATURES Real hardware telemetry Exposure readings come from the camera's own sensor data, continuously updated — not a guess based on screen brightness. This is the same kind of reading a dedicated handheld meter gives you. Aperture & shutter priority Choose which one you want to control — set your aperture and get the matching shutter speed, or set your shutter and get the matching aperture. Average and spot metering Meter the whole frame, or tap anywhere on screen to spot-meter exactly the area you're pointing at. Meter for shadows, mids, or highlights Choose which part of the scene's brightness range you want exposed correctly. It's your call — Telemetry just does the math. Exposure compensation Fine-tune the reading up or down in third-stop increments. No accounts. No ads. No tracking. Telemetry doesn't collect any data, doesn't require sign-in, and doesn't have ads. It's a tool, not a platform. Whether you're shooting film, running manual exposure on a digital body, or just want to understand the light you're working with, Telemetry gives you a reading you can actually trust.
