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.
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. lux image logger
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). Whether preserving a Rembrandt, convicting a criminal, or
In the high-stakes worlds of forensic photography, cultural heritage digitization, and scientific field research, an image is more than a visual record—it is a data point. The standard JPEG header or smartphone EXIF data fails to capture critical environmental, lighting, and chain-of-custody information. Enter the Lux Image Logger : a dedicated hardware-software system designed to embed, verify, and retrieve high-resolution photometric and situational metadata in real time. 1. Core Philosophy: Why "Lux"? The name "Lux" (the SI unit of illuminance) signals the system’s primary differentiator. While conventional cameras log time, date, and GPS, the Lux Logger focuses on light —its quantity, quality, color temperature, and stability. For applications like archaeological site documentation or art authentication, knowing the exact illuminance at capture (e.g., 3200K at 480 lux ±2%) allows later analysts to correct for color casts or prove that lighting was non-damaging to sensitive pigments.
