Studio Camera

Control your professional camera from your phone. Studio Camera connects to Sony, Canon, Nikon, Fujifilm, Panasonic/Lumix, and OM System cameras over Wi-Fi Direct, giving you live view, exposure control, remote capture, and media management in one app.

Built with Kotlin Multiplatform for Android and iOS.

What it does

• Remote camera control: adjust ISO, shutter speed, aperture, and EV from your phone
• Live view: see what your camera sees with low-latency streaming
• Multi-brand support: works with six major camera brands out of the box
• Easy pairing: connect via QR code, NFC (Android), or manual SSID entry
• Overlays: grids, aspect ratio guides, histogram, focus peaking, zebra, and safe zones
• Media management: browse, preview, download, share, and delete photos and videos
• Mock mode: a built-in simulator for development and testing without a real camera

Getting started

You'll need JDK 25+, Android Studio (or IntelliJ IDEA), and Android SDK API 35+. For iOS builds, you'll also need macOS with Xcode 16+.

git clone https://github.com/LennyObez/studio-camera.git
cd studio-camera

# Build a debug APK
./gradlew assembleDebug

# Install on a connected device
./gradlew installDebug

# Run lint and tests
./gradlew check

iOS builds require macOS with Xcode. Open iosApp/ in Xcode or use KMP tooling.

How it works

The phone connects to the camera's Wi-Fi network, then Studio Camera probes brand-specific API endpoints to discover what it's talking to. Each brand has its own protocol implementation, and a central router delegates to the right one.

Data flows in one direction: UI → navigation component → repository → data source. State is managed with Kotlin StateFlow, and the DI layer (Koin) keeps things modular with per-feature scopes.

The entire business logic lives in shared Kotlin Multiplatform code (commonMain), with platform-specific implementations only where needed (networking engines, camera preview, NFC).
