How to Capture Stereoscopic 3D Video: Techniques for Immersive Depth
Capturing the third dimension has long been a pursuit of visual storytellers, often requiring specialized eyewear or complex projection systems. However, a fascinating technique exists that allows viewers to experience depth on a standard screen: the wigglegram.
While traditionally applied to still photography, bringing this stereoscopic effect to motion video presents a unique set of challenges and rewards. By understanding the mechanics of human vision and the geometry of light, one can transform a flat digital plane into an immersive, pulsating window of depth.
The principle relies on stereoscopic imaging—capturing two distinct perspectives of the same subject, mimicking the approximate 65mm spacing between human eyes. To create a "glasses-free" 3D effect, the editor must alternate between these two perspectives rapidly.
This flickering switch tricks the brain into perceiving volume and spatial distance. Whether using a dual-camera rig or a vintage beam splitter, the goal is to create a natural-feeling depth that pulls the viewer into the scene.
