Holograms need a material to record interference fringes. There are many materials that can record fringes.

- Silver Halide Chemistry: Theory and Practice of Making Silver Halide Plates and Development.
- Silver Film Comparison Chart: A quick comparison of the qualities of different commercially made films.
- Dichromated Gelatin Chemistry: Theory and Practice of DCG Plates and Development.
- Polymer Film and Processes: Many commercially sold holograms are made from photopolymers.
- Photoresist: Taken from the electronics industry, this material can make relief holograms for embossing.
- Coating Methods: Coating Gelatin on to a glass plate is an art in itself.
- Crystals: There are many crystals that can record an image. The cost and exposure energy required is very high so they are not often used for holography.
- Embossed Holograms: These are like the holograms seen on credit cards.
- Gelatin: Used as the suspension medium to hold light sensitive particles.
