When we go to the Botanic Gardens, I usually do my nerdy thing and try to take panoramic images or get a pair of images that I can merge into a 3D anaglyph. I leave the artsy stuff to Verna.
A few weekends ago, I stood in front of these topiaries in the children’s garden and leaned to the left and then to the right; each time I snapped an image of the scene. If the lateral distance of the camera’s aperture is about the same as the human inter-pupil spread and the camera is held at the same horizontal angle and the same distance from the subject, then a 3D picture can be produced.
You will need red/cyan or red/blue 3D glasses. See Bob’s 3D Stuff page for details. Click on the image for the PNG Hi-resolution version, or, if you don’t have the 3D glasses, you can view the non-stereoscopic image here.
