A method of manufacturing optical elements, such as for head-up displays, from holographically recorded interference patterns in a dichromatic gelatin is disclosed. The exposed hologram pattern is developed through hydration, the hydrated hologram gelatin is dehydrated by contacting the hydrated gelatin with a mixture of isopropyl alcohol and an inert anhydrous fluid, such as a liquid fluorinated hydrocarbon solution. The dehydrated hologram pattern can then be subsequently stabilized, for example, by baking.
