Configuring Photobooth (by Pagekite)

1. Navigate to the Directory: In the terminal, navigate to the `DIY-Photobooth` directory you cloned earlier:

   cd DIY-Photobooth

2. Edit the Configuration File (Optional): You can customize the settings in the `config.ini` file. For example, you can change the countdown timer, the number of photos taken, and the output directory. Use a text editor like `nano` to edit the file:

   nano config.ini

3. Run the Photobooth: Run the photobooth script:

   python3 photobooth.py

Making Photobooth Start on Boot

To make the photo booth start automatically when the Raspberry Pi boots, you can use systemd. Create a service file:

sudo nano /etc/systemd/system/photobooth.service

Add the following content to the file, replacing `/home/pi/DIY-Photobooth/photobooth.py` with the actual path to your `photobooth.py` script:

[Unit]
Description=Raspberry Pi Photo Booth
After=graphical.target
Wants=graphical.target

[Service]
User=pi
WorkingDirectory=/home/pi/DIY-Photobooth
ExecStart=/usr/bin/python3 /home/pi/DIY-Photobooth/photobooth.py
Restart=always

[Install]
WantedBy=graphical.target

Save the file and exit the editor. Then, enable and start the service:

sudo systemctl enable photobooth.service
sudo systemctl start photobooth.service

Now, the photo booth will start automatically when you boot your Raspberry Pi.

Customization and Enhancements

The real power of a Raspberry Pi photo booth lies in its customizability. Here are some ideas for enhancements:

• Custom Overlays and Branding: Add custom overlays with your event logo or theme. Most photo booth software allows you to specify overlay images.
• Social Media Integration: Allow users to share their photos directly to social media platforms. This usually requires configuring API keys and OAuth authentication.
• Printing: Integrate with a photo printer to provide instant prints. You’ll need to install printer drivers and configure the software to send images to the printer.
• Animated GIFs: Create animated GIFs from a sequence of photos.
• Video Recording: Add the ability to record short video clips.
• Green Screen: Implement a green screen feature to allow users to choose from a variety of backgrounds. This requires a green screen backdrop and some image processing techniques.
• Facial Recognition: Use facial recognition to add fun filters or effects to the photos.
• Cloud Storage: Automatically upload photos to cloud storage services like Google Drive or Dropbox.
• Remote Control: Control the photo booth remotely using a web interface or a mobile app.
• Add Lighting: Good lighting is essential for high-quality photos. Consider adding an external light source to improve the lighting conditions. A ring light is a popular choice.
• Physical Enclosure: Build or buy a physical enclosure for your photo booth. This will make it look more professional and protect the components.
• Button Integration: Connect a physical button to trigger the photo capture. This can be done using the Raspberry Pi’s GPIO pins and a simple Python script.

Example: Adding a Custom Overlay

Let’s say you want to add a simple overlay to your photos. Here’s how you can do it using Photobooth (by Pagekite):

1. Create an Overlay Image: Create a PNG image with transparency in the areas where you want the photo to show through. The image should be the same resolution as the photos taken by the camera. For example, you might create an image with a border or a logo in the corners.
2. Save the Overlay Image: Save the image in the same directory as the `photobooth.py` script. For example, you might name it `overlay.png`.
3. Modify the `photobooth.py` Script: Open the `photobooth.py` script in a text editor.
4. Add the Following Code: Add the following code to the script, after the line where the photo is saved (usually after the `camera.capture` line):

   from PIL import Image
   
   try:
       # Load the overlay image
       overlay = Image.open("overlay.png").convert("RGBA")
       # Load the photo
       photo = Image.open(filename).convert("RGBA")
       # Resize the overlay to match the photo size
       overlay = overlay.resize(photo.size)
       # Overlay the images
       photo = Image.alpha_composite(photo, overlay)
       # Save the combined image
       photo.save(filename, "PNG")
   except Exception as e:
       print(f"Error adding overlay: {e}")

5. Install Pillow (PIL): If you don’t already have it, install the Pillow library:

   sudo pip3 install pillow

6. Run the Photobooth: Run the photobooth script again. Now, the photos will have the overlay applied to them.

Remember to adjust the path to the overlay image if necessary.
