StereoPhoto Maker vs 3DCombine: Freeware Specialist vs Commercial All-in-One
3DCombine is a commercial stereo editor for photos and video that has been sold for many years, with features such as depth-map-based conversion. Against freeware StereoPhoto Maker, the comparison is about what the paid route adds and what it does not.

Choose SPM if…
Your work is real stereo pairs — shot, aligned, converted, printed, archived. That is SPM’s entire design centre, it is freeware, and it is the one still shipping updates in 2026.
Choose 3DCombine if…
You specifically want its depth-map/2D-to-3D conversion features or stills+video in one paid package, and its current version suits your system. Synthetic 2D-to-3D is a different craft from editing true pairs; know which one you are buying.
