A hologram is created with photographic projection

Holography is a method that allows the light scattered from an object to be recorded and later reconstructed. It appears as if the object is in the same point relative to the recording medium as it was when recorded. The picture changes as the place and course of the viewing system changes.

It changes precisely the exact way as if the object were still there. It makes the recorded image emerge three dimensional which is termed as Hologram.

There are different types of holograms as 2d & 3d holograms. These holograms are truly three-dimensional and free-standing image that does not simulate spatial depth or necessitate a special viewing device.
There are different names by which the holograms are categorized as reflection hologram, transmission hologram and embossed hologram etc.

The reflection holograms are viewed when lit from the front, while transmission hologram can be seen by unblemished light through it from the back side.
