ABSTRACT
A multicolour holography study case will be presented with emphasis on colour control in different silver-halide materials. It has been systematized in order to compare the results obtained with Agfa 8E 75HD to those with Slavich PFG-01. Some experiments were made and the emulsion was manipulated before exposure to achieve high quality multicoloured white light reflection holograms. This work has therefore been developed in order to obtain the various colours in a very well controlled way.
Keywords: colour control; emulsion thickness; silver halide materials.
