Explains making real stereograms with ordinary gear: two handheld photos by shifting weight (roughly shoulder-width baseline), or 3D video from one moving camera by offsetting frames (example: 50 fps → 20 ms frames, a 4-frame/80 ms offset gives ~80 mm stereo), using free tools GIMP for alignment and Shotcut for video. Describes viewing methods cross-eyed freeview and parallel freeview, explains interpupillary reference (~70 mm) and hyper/isostereo effects, and demonstrates drone/GoPro workflows and mirror or stereolens alternatives.
