SolX — Golden-Hour Photography Companion
Architecture & Technical Challenge
Photographers and cinematographers require precise down-to-the-minute calculations of the golden hour and blue hour to capture peak natural lighting. SolX implements rigorous spherical trigonometry and NOAA solar position algorithms locally on-device without requiring network calls.
Core Engineering Innovations
- Dynamic Solar Compass: Real-time device gyroscope and compass fusion visualizing the exact sun trajectory over the horizon.
- Tactile Shutter Simulation: Custom manual exposure, ISO, and shutter speed dial with precise mechanical vibration feedback.
- Zero Cloud Dependency: All astronomical ephemeris models execute purely in client-side Swift math for remote shooting expeditions.
