Leica 250 exposure camera instructionsThe 250-exposure leIca camera Every photographer, whether amateur, profes- sional or scientific, finds himself at times in situ- ations in which it is not really sufficient to be able to make 36 exposures at one loading. There is, for instance, the press photographer who may lose irretrievable opportunities if he is compelled to insert a new film chamber while interesting events are in progress: there is the beach photo- grapher, to whom the changing of a film chamber may easily mean the loss of an order: there is the amateur on his holiday tour or the explorer further afield, both of whom have only rareopportunities of getting their exposures: or there is the scientific photographer who has to reproduce an old volume page by page, for which purpose it would be an unwelcome waste of time to have to put in a new film after every 36 pages, apart from the inconvenience of having to carry about a whole series of film chambers for the work.
