What you get
Per-event configurable. The kiosk reads event.json at startup and renders whichever style matches the room.
Classic photobooth. Operator places buttons in the visual editor; touch zones are pixel-perfect.
Horizontal swipe carousel. Center item scales up and gets full opacity; auto-wraps at edges.
Vertical list with descriptions. Accessibility-friendly — readable from across the room.
iOS-style 3D-ish rotating carousel on a dark gradient with a pink-glow center card. Premium events.
Capture
All four modes go through one pipeline. Boomerang and GIF use FFmpeg server-side (bundled in the installer). AI background routes the photo through OpenAI gpt-image-1 or Google Gemini 2.5 Flash Image — operator chooses, per preset.
One ICameraService interface; three implementations — Canon EDSDK, Sony Camera Remote SDK, OpenCvSharp webcam. Picked per event with optional fallback. The webcam service falls back to synthetic frames if no hardware is attached, so dev / CI runs without a DSLR.
Delegated to the provider's image-edit endpoint — no local segmentation, no mask compositor to drift. Operator-authored prompts can pull guest input fields (jersey number, name) via {fieldId} tokens.
Privacy + compliance
Three independent on-disk streams under %LOCALAPPDATA%: scrubbed Serilog logs, append-only JSONL audit trail, opt-in counter telemetry. Consent decisions, admin sign-ins, PIN changes, API-key rotations, retention purges, and R2 deletes all land in the audit log. Keep it indefinitely; it's tiny.
Production-grade Windows installer via Velopack. Background auto-update that never restarts the booth mid-session — new bits apply on the next cold start.
