ABSTRACT:
A rotary magazine which permits the storage and the consecutive, rapid, exposure of a plurality (i.e., preferably twenty-four) of glass photographic plates. Holders for the photographic plates are pivotally connected to the periphery of a wheel in equal spaced-apart relationship, and are spring loaded so that they can be rotated in only one direction. The plates are rapidly exposed, one at a time. Unlike the prior art, and especially with regard to holograms, the magazine eliminates the undesired lapse of time that is inherent in manually changing the photographic plates. Therefore, less correlation is necessary for temporal changes which occur while "photographing" (i.e., recording) the same, but rapidly time-changing, subject scene (e.g., icing of water droplets). The magazine is particularly well suited to obtain a large number of holograms in rapid sequence.
