Raspberry Pi Photo Booth Setup

I'm seeking a freelance tech expert to assist in setting up a Raspberry Pi 4 as a fully functional photo booth system. The primary goal is to create an automated and reliable photo booth for an event or mall, focusing on touchless or single-button operation for ease of use.

Key Requirements:
- Flash Raspberry Pi OS (64-bit) on the SD card
- Enable headless access via SSH over LAN or Wi-Fi
- Connect and configure a Canon EOS R50 DSLR with the Raspberry Pi
- Use gphoto2 or an equivalent tool to:
- Trigger photo capture through GPIO input
- Automatically transfer captured photos to the Pi
- Add an event-specific template overlay (PNG frame) to photos
- Print photos automatically using a Canon PIXMA printer
- Implement a folder-based photo backup system
- Optional: Set up live preview and/or VNC for remote access

Project Goals:
- Achieve a fully automated photo booth setup
- Ensure a plug-and-play system that is reliable and beginner-friendly

Available Hardware:
- Raspberry Pi 4 (4GB)
- Canon EOS R50 (DSLR)
- Canon PIXMA printer
- HDMI cable, USB trigger cable, and power supply

Ideal Skills and Experience:
- Proficiency in Raspberry Pi setup and configuration
- Experience with DSLR camera integration and photo capture automation
- Familiarity with gphoto2 or similar software
- Ability to implement template overlays and automated printing
- Knowledge of GPIO input handling and photo backup solutions

If you have the expertise to bring this project to life, I would love to hear from you!
