Whether preserving a Rembrandt, convicting a criminal, or tracking a moth, the humble measurement of lux—faithfully logged and cryptographically sealed—turns every image into evidence.
The logger listens for the camera's hot shoe firing signal, PC sync port pulse, or detects shutter vibration via its IMU. Latency is typically <5 ms. At the exact frame midpoint, the logger records a 100ms window of sensor data (fastest lux sensors sample at 400 Hz). lux image logger
Moreover, as computational photography matures, smartphones could embed miniature lux sensors directly next to the camera module. An Android or iOS API could then allow any app to access a continuous light log—turning billions of phones into environmental light-sensing networks. The Lux Image Logger is not a mass-market gadget. It is a professional tool for those who understand that photography is time resolved radiometry . By transforming a camera into a calibrated scientific instrument, it closes the loop between the world as illuminated and the world as recorded. In an era of deepfakes and metadata stripping, the Lux Logger offers a counterweight: verifiable, light-based truth at the moment of capture. Whether preserving a Rembrandt, convicting a criminal, or
