Anaglyph 3D
Perhaps you're familiar with the cardboard 3D glasses with one red and one blue-green lens. These allow you to see "anaglyph 3D".
Here's how it works:
- To create a 3D image, you need two images: one for the left eye and one for the right eye. They are almost identical, but very slightly shifted.
- In an anaglyph image, these two images are superimposed and colored in different colors, for example:
- Left image: more red
- Right image: more cyan (a mixture of blue and green)
- Your 3D glasses also have color filters:
- The red glass primarily lets the red image through.
- The cyan-colored glass primarily allows the cyan-colored image to pass through.
- Each eye sees a different image. Your brain then combines both images, giving you the sensation that the image is "coming out" of the screen.
Anaglyph 3D is popular because it is very inexpensive: all you need is a special image and a simple pair of cardboard color glasses.
You can create an anaglyph image yourself – it's not exactly easy. However, we offer courses on this from time to time.
Create your own anaglyph image.
Instructions for anaglyph 3D: first take the photos correctly, then assemble them on the computer. The basic principle is always the same: two slightly offset shots of the same subject combine to create a 3D image for red-cyan glasses.
