3D Greetings

Homegrown Evolution’s holiday gift to our readers is a headache. Well, to be precise, we offer you three dimensional images of two of our favorite garden plants. Above, the prickly pear cactus (Opuntia ficus-indica) and, below, spearmint (Mentha Spicata). To view these two images in three dimensions follow these instructions, specifically the bit about “parallel viewing”. Be persistent, like all good things it might take some practice.

We taught ourselves how to free view three dimensional images a long time ago and, in additional to it being good for your eye muscles, it opens up a whole world of fun with old stereoscopic images such as these.

To make your own stereographs all you need to do is take two pictures slightly spaced apart. As long as your subject doesn’t move you can do it with just one camera. Full instructions here.

For those of you who, after an hour of reviewing those parallel viewing instructions, now have a headache can’t uncross your eyes, we suggest downing a few cups of eggnog to make things just fine in the new year.

  1. I learnt to freeview as a kid while reading a feature in Junior National Geographic. So this came really easy to me. I love it! Can you take stereo pictures with a normal camera?

  2. qaish,

    Yes, it’s easy. All you do is take a photo and slide your camera a few inches to the right or left and take another photo. You can even do it without a tripod if you have a steady hand. Of course, this only works for subjects that don’t move. Good luck!
