Overview
A professional camera assistant and digital sensor emulator for iPhone and iPad, designed around manual capture, real-time visual processing, classic digital looks, and private on-device workflows.
Contributions
- Built native SwiftUI and AVFoundation capture flows with explicit camera controls and still/video processing paths.
- Implemented real-time LUT and parametric image adjustments through Core Image and Metal-backed rendering.
- Added RAW/DNG-oriented workflows, offline scene intelligence, local photo handling, and camera-focused monitoring tools.
- Designed the product to work without an account, tracking scripts, or external media uploads.
System design
| Capture | AVFoundation manages camera devices, exposure, focus, formats, and photo/video output. |
|---|---|
| Rendering | Core Image and Metal apply LUTs, color controls, and live preview processing. |
| On-device intelligence | Core ML and Vision support scene-aware recommendations and gallery assistance without sending media off device. |
| Privacy | Media stays in the local Photos workflow and the application does not require account creation. |
Outcome
A camera product whose technical presentation emphasizes predictable capture behavior, local processing, and creator control rather than social or cloud features.
