B.Allan Andersen does the “cha-cha” shooting a 3D image with one camera.
Shooting 3D requires shooting 2 images slightly separated horizontally about the same distance as the width between your eyes. There are all types of sophisticated camera setups to do this. Interestingly, you can shoot 3D with any conventional 2D camera by shooting 2 images in sequence. As long as there is no movement in your scene the effect will work well.
Here’s how you do the cha-cha:
- Stand straight with your legs comfortably set in place
- Shift your weight to the left leg and shoot 1 image
- Shift your weight to the right leg until you notice your whole body shifts, then shoot the 2nd image
That is the basic idea, you should experiment to get the right amount of separation between the shots; you will get a feel for that over time. You can also use a tripod and shift it to get a more accurate set of shots. If you get really into this you can buy a slide bar for your tripod to be even more precise.
Later you can prepare the images in side by side crossview format and view the effect. You can also use software to make an anaglyph version from the original 2 images. There is excellent free software that will let you align and prepare your images into many popular viewing formats including anaglyph. I highly recommend the free StereoPhoto Maker software for this task.
