Making [etched] holograms with a pen plotter
TL;DR
A pen plotter was used to create hand-drawn holograms, offering a unique approach to holography without requiring prior knowledge or complex math. This method emphasizes intuitive understanding through simple techniques.
✦ Why It Matters
Experiment with a pen plotter to create unique holographic art today.
Key Takeaways
- Use a pen plotter to create unique holographic designs.
- Experiment with different materials for etching to find the best results.
- Understand how light reflection can create depth in images.
- Explore DIY holography without needing expensive equipment.
How It Works
The key insight is that the curvature of reflective ridges determines how light reflects and creates a virtual image. By etching surfaces with varying curvature, the author can manipulate how highlights move in relation to the viewer's perspective, effectively simulating depth.
