Imatest Spectral Sensor vs f/64

Whether you're calibrating camera systems on a modular test stand or matching practical lights and studio strobes for a multi-day shoot, SpectralSensor delivers absolute precision directly to your phone or computer. Interface seamlessly with your Imatest Spectral Illuminance Color Sensor (ISICS) and Low Light Illuminance Sensor (ILLIS) to take the guesswork out of your exposure, color science, and system calibration. Multi-Sensor Dashboard: Instantly discover, connect, and manage multiple physical Imatest sensors via secure Bluetooth. Easily switch between devices or run a live "Continuous" polling mode across your entire setup. Comprehensive Metrics: View real-time, exhaustive data readouts including Illuminance (Lux/fc), Correlated Color Temperature (CCT), CRI (Ra alongside granular R1-R15 bar charts), SDCM, Duv, Irradiance, and S/P Ratio. Advanced Visualizations: Analyze your light with highly interactive tools. Scrub through the Spectral Power Distribution chart for exact wavelength intensities, or swipe through live-updating Chromaticity Maps (CIE 1931, 1960, 1976, and CIELAB) that pinpoint your exact color coordinates. Illuminance Tracking: Track lux over time with an interactive history chart. Step away from the sensor and enable "Large Mode" for a massive, high-contrast lux readout visible from across a dark studio. Data Portability: Instantly format your entire data payload into a clean text string for emails using the "Copy All" tool, or save your complete session locally as a comprehensive CSV file. Mock Sensor Analysis: Open previously saved CSV files to automatically spin up a "Mock Sensor." This loads historical data back into the live UI, allowing you to use the interactive charts and scrubbing tools on past captures exactly as if the physical hardware was still connected. (Note: To protect your data integrity, the live recording trigger is strictly disabled when a Mock Sensor is active). Built for working professionals. SpectralSensor features a completely ad-free, distraction-free interface focused entirely on functionality, stability, and accurate metrics. Please note that SpectralSensor is a specialized hardware utility. While the application can be installed and explored using the internal mock sensor mode, live environmental measurements require proprietary Imatest hardware (ISICS or ILLIS), which is sold separately. Take complete control of your lab and set lighting with the official companion app for Imatest measurement equipment.

f/64 is a camera with one promise: what the sensor saw is what you keep. PURE RAW Every shot saves a true Bayer RAW (DNG) next to the HEIC. No AI, no computational tricks, no Deep Fusion, no Smart HDR. Your negative, untouched. FULL MANUAL Shutter speed, ISO, exposure bias, focus and white balance, each on its own precise dial with real photographic stops. Lock any parameter, keep your settings between sessions. TOOLS THAT MATTER - Focus peaking, zebra stripes and a focus loupe - Live luminance histogram - All lenses including the 8x sensor crop - RAW exposure brackets (hold the shutter) - Subject tracking, AE/AF lock, horizon level - 1:1, 4:3 and 16:9 framing; the DNG always keeps the full sensor - Optional watermark and an Instagram-ready story card - Optional geotagging QUIET DESIGN A monochrome interface that stays out of your way, rich haptics and signature sounds. Photos go straight to your library; the app collects nothing about you. FREE, HONESTLY No ads, no subscriptions, no locked features, ever. If f/64 saves you a shot you love, there is a voluntary tip jar in the settings. Named after Group f/64, Ansel Adams and friends, who believed a photograph should be sharp, honest and made by hand.
