Kiosk Photo Capture App

I'm looking for a simple, full-screen photo kiosk app for customers.

Requirements:
- User inputs: Name and WhatsApp number
- Countdown options: 5s or 10s
- Live camera view (DSLR connected to PC)
- Photo taken after countdown, saved in a folder
- Photo renamed using name + phone
- User info and photo filename saved to a database (JSON or SQLite)
- Photo sent to customer's WhatsApp via API

DSLR is already connected to PC and controlled via digiCamControl.

The system should have a clean kiosk appearance (no camera settings shown) and a friendly, colorful design.

Ideal skills and experience:
- Proficiency in Python
- Experience with DSLR integration and API usage
- Familiarity with database management (JSON/SQLite)
- Ability to create user-friendly, colorful interfaces
