In this paper the steps necessary for plate making and processing for dichromated gelatin holography will be discussed.. This article will refer to work of other people as well as work done in my own laboratory. When dichromated gelatin is used as a recording-medium special effects will occur. These effects are not, or not in the same extension, present when other recording-media are used. Mostly these effects are caused by the difference in which the recording is stored in the photo-sensitive layer. Whereas, in the case of silverhalide, the change of refractive-index of the silver-molecules embedded in gelatin is used, in the case of dichromated gelatin the change of retractive- index of the gelatin itself is used. This difference has a major influence on parameters such as efficiency, spectral replay response and resolution.
