Talking about the shooting skills of holographic photos

1. Holography is a photographic method that can record and reproduce three-dimensional (stereoscopic) images of objects without lenses. It is a technology that can record the amplitude and phase information of light wave front from objects and reproduce this light wave when necessary.

2. Due to the mutual interference between the object light and the reference light on the holographic negative, a very complex and fine interference fringe pattern is formed. These interference fringes record the amplitude and phase information of object light changing with its contrast and position.

3. Holographic negatives become holograms after conventional development and fixation. The appearance of hologram seems to have nothing to do with the appearance of the original object, but it records all the information of the object light in the form of optical coding.
