Greenscreen or AI background removal? This is a question many ask when looking to rent a modern photo booth. Both technologies allow replacing the background with any motif – but the differences are bigger than you might think. In this article, you'll learn how both systems work, where their strengths and weaknesses lie, and which technology is the better choice for which application.

1. How Does Greenscreen Work?
Greenscreen technology (also called chroma-keying) has been the standard in film and television for decades. The principle is simple: a solid-colored background – usually bright green or blue – is replaced with another image or video during post-processing.
How it works technically:
- Color-based detection: The software recognizes a specific color range (e.g., RGB 0, 255, 0 for green)
- Pixel replacement: All pixels in this color range are made transparent
- Background overlay: The new background is placed behind the image
- Edge smoothing: Software algorithms smooth the transitions between person and background
Why Green?
Green is the furthest color from skin tones in the RGB spectrum. This prevents faces and hands from accidentally becoming transparent. Blue is the second choice but is used less often because clothing more frequently contains blue elements.
Important: Anyone wearing green clothing will become partially transparent with greenscreen – that's the classic "greenscreen fail"!
2. How Does AI Background Removal Work?
AI-based background removal is a modern alternative that works completely without a colored background. Instead of focusing on colors, artificial intelligence analyzes the image and automatically recognizes what is foreground (person) and what is background.
How it works technically:
- Deep Learning: The AI was trained with millions of images to recognize people
- Semantic Segmentation: Each pixel is classified as "person" or "background"
- Contour Recognition: The AI precisely recognizes hair, clothing edges and complex outlines
- Real-time Processing: Modern AI models handle 30+ images per second
Which Models Are Used?
Photo booths typically use specialized models:
- U²-Net: Classic for precise portrait segmentation
- DeepLabV3+: Google's model for semantic segmentation
- MediaPipe: Google's real-time solution for mobile devices
- Custom Models: Specially trained models like at 030Box
030Box Technology: We use an optimized AI model specially trained for event situations – even in difficult lighting conditions and group photos.
3. Quality Comparison
Which technology delivers better results? The answer: It depends!
Greenscreen Quality
Advantages:
- Perfect edges under optimal conditions
- No computing power needed for AI
- Proven technology for decades
- Well-controllable results
Disadvantages:
- Problems with green clothing or accessories

In Practice: At events, AI-based systems often have the advantage as they are more flexible and less error-prone. Greenscreen excels especially in professional studio settings with controlled conditions.
4. Setup & Requirements
The choice of technology also has practical implications for setup and usage.
Greenscreen Setup
Required:
- Greenscreen Wall: At least 2.5m wide, 2m high (for individuals)
- Special Lighting: 2-4 additional lights just for the greenscreen
- Distance: At least 1.5m between person and greenscreen (to prevent shadows)
- Setup Area: About 3x4 meters total
- Setup Time: 30-45 minutes
Challenges:
- Greenscreen must be wrinkle-free and taut
- Lighting must be perfectly balanced
- More equipment = more transport effort
- Sensitive to ambient light
AI Setup
Required:
- Any Background: White wall, curtain, or even the normal location
- Standard Lighting: Only the person needs to be well lit
- Distance: No special requirements
- Setup Area: About 2x2 meters
- Setup Time: 15-20 minutes
Advantages:
- Minimal space requirements
- Quick setup and teardown
- Less equipment = easier transport
- Works even in unusual locations
030Box Practice: Thanks to AI technology, we can set up the booth even in tight locations or difficult lighting conditions. You save space and we save time on setup!
5. Cost Differences
