What's the difference between 3D photography and traditional photography?

1, holographic photos are different from ordinary popular science photos. Under proper illumination, the scene displayed on the hologram is three-dimensional, and all sides of the scene can be seen.

2. Ordinary photography can only store the spatial distribution of the light intensity of the object being photographed, which can't meet the requirement that people want to perceive the real 3D scene in a specific environment; Holography is called "holography" because it records the interference fringes between the object light wave and the corresponding reference light wave, thus recording all the light field information including the amplitude (light intensity) and phase of the object.
