Difference Between Holography and Photography

What is holography?

Holography is a technique for creating three-dimensional images by utilizing light interference and diffraction. It makes use of a coherent and monochromatic light source. To regenerate an image, a hologram is required.

What is photography?

Photography is a technique for producing two-dimensional images of three-dimensional objects. After striking the object, the reflecting light reacts with the chemical coating of the film. To focus the object on the photographic plate, a lens is required.

Holography vs photography:
  • Holography is used to generate 3-dimensional images, while photography is used to generate 2-dimensional images.
  • Holography is interference and diffraction of light, photography uses the reflection of light by the object to the photographic film.
  •  Holography is a source of light that should be monochromatic and coherent, while photography is not a special type of light source that is needed.
  • Nolen's are required to generate the Holograph, photography the lens is required to focus on the object and generate the photography.
  • Holography has a high information capacity, whereas photography has a lower information capacity.
  • Holography is multiple images that can be superimposed together, while photography is multiple images that can't be superimposed together.
