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.; [http://en.wikipedia.org/wiki/Hologram#Materials Wikipedia] : Wikipedia's summary of Holographic Recording Materials.] ; [http://en.wikipedia.org/wiki/Periodic_table_%28standard%29 The Elements] : The Periodic Table Chart of the Elements]; '''[[Books]]'''
