A professional Light Meter and Ansel Adams Zone System companion app built natively for Android using Jetpack Compose and the modern Camera2 API.
ZoneMeterPro is designed for professional photographers who demand precise control over their exposure calculations, especially when using the classic Zone System or shooting analog film.
- Ansel Adams Zone System: Map real-world luminance directly into Zones (0 to X) to visualize highlights and shadows before taking the shot.
- Director's Viewfinder: Compose your shots perfectly by simulating various film and digital formats:
- 35mm
- Medium Format Digital (4433)
- 645, 6x6, 6x7, 6x9
- Large Format (4x5, 8x10)
- Modern Transparent UI: Smooth, iOS-style vertical focal length dial with dynamic equivalent focal length calculations based on format cropping and letterboxing.
- Ultra-wide & Multi-lens Support: Dynamically switches to ultra-wide lenses depending on the physical capabilities of your Android device (Hardware ZoomState mapping).
- Auto-ETTR (Expose To The Right): [In Development] Deep Camera2 API integration to intercept RAW sensor data for absolute high-precision highlight clipping prevention.
