Shutter Test: Analog Cameras

Calibrate and verify your vintage film cameras with precision. Shutter Test is a specialized workbench designed for camera collectors, repair technicians, and analog photography enthusiasts who need reliable shutter speed measurements.

MEASUREMENT MODES
- Optical Sensor Input: Analyze high-speed optical waveform files or sensor inputs with microsecond resolution.
- Acoustic Capture: Record shutter curtain sounds and leaf shutter clicks directly using your device microphone.
- Manual Input: Quickly log bench readings from dedicated hardware testers.

DETAILED WAVEFORM ANALYSIS
- Interactive Signal Inspector: Zoom into audio and optical traces to inspect opening and closing transients.
- Precision Markers: Position start and finish markers manually or use automatic peak detection.
- Accurate Metrics: Instantly view measured exposure time, percentage deviation, and exposure error in EV stops.

CAMERA INVENTORY & PROFILES
- Manage your collection with custom camera profiles.
- Configure focal-plane and leaf shutters with standard or custom speed progressions.
- Track speed accuracy across individual shutter speeds from 1s to 1/1000s and beyond.

HISTORY & REPEATABILITY
- Keep comprehensive records of calibration sessions.
- Compare multiple test runs to verify shutter curtain tension and timing consistency.
- Filter test runs by camera, test method, or date.

DATA EXPORT
- Export detailed test logs and measurement summaries as formatted CSV tables or print-ready PDF reports.
- Share calibration records with clients or keep them for your workbench archive.

Built by analog photography enthusiasts to keep classic cameras shooting accurately.
