<p>The camera back is fitted with guides to position a slider on which are mounted two cassette holders. Each cassette is for a different format picture taken in conjunction with a sliding format frame. Separate ground glass screens are fitted to each cassette while locating grooves on the guides accurately position the cassettes. In the case of several small pictures taken on one cassette, e.g. three different profiles of head and shoulders, the slider is moved only partway across the camera while the format frame remains stationary. The camera enables rapid pictures to be taken at different formats.</p> |
