Edmond Lambebt Coninok, 53, Chancery Lane, Lon don, “Improvements in Photographic Shutters.”—Sep tember 5th. Specifications Published. 5,227. April Zrd, 1890.—“ Camera with Roller Slide and Shutter.” C. Whitney, Chicago, Illinois, U.S.A. The camera belongs to the instantaneous or detective type, and is made in the form of an opera glass, book, or other like article. When in use, the front of the camera is drawn out and held by spring catches. A sensitive ribbon mounted on a roller slide is preferably used, or the sensitive paper may be cut in sheets and fed into position by rollers. In the roller slide the roll of sensitised paper is placed in a tube, through a slit in one side of which the end of the ribbon is drawn, passed round the back of the exposure chamber, and connected by a fastener to strap attached to the receiving roller. In some forms of the roller slide there is a knife actuated by a roller, which cuts the ribbon into lengths as it enters a receiv ing chamber. In another form the film is stored in sheets, and transferred to the receiving chamber by rollers. One form of the shutter consists of two slides, one of which slides above the other ; the lower slide has an exposure aperture which passes in front of the lens aperture, and is then covered by the upper slide. A spring catoh is fitted for holding the shutter open for slow exposures. The shutter is preferably fitted between the lenses, and actuated by spiral springs. In another form of the shutter a rotary disc, with several apertures to give a succession of exposures, is used. 5,458. April ~LOth, 1890.—“Cameras and Change-Boxes.” H. R. Hume, 6, Allen Terrace, Kensington High Street, and E. W. Pabfitt, 18, Gatcombe Road, Tufnell Park, both in London. In a detective or hand-camera, plates, enclosed in sheaths having side projections at one end, are placed in a receptacle at the top of the camera, the plates being pressed towards the bottom by a spring. Within the camera, and below the receptacle, slides a carriage having racks on the top, on to which the projections drop in succession. The carriage is slid towards the back by a lever at the base of the camera, which lever actuates a sliding plate provided with a spring pin, which engages with recesses in the sliding carriage. When the lever is moved towards the front of the camera, the pin is withdrawn from the recess. The lever also works a ratchet indicator. As the front ends of the plates drop in succession from the ledge, they are held by a spring in a vertical position for exposure. • Leeds PHOTOGRAPHIC Society.—The hon. sec. of the above Society, Mr. S. A. Warburton, informs us that, in connection with the Photographic Exhibition which is to be held in the Municipal Art Galleries during the coming winter, in addition to the medals offered by the Fine Art Gallery Committee, the Committee of the Leeds Photographic Society have decided to offer the following special medals for competition amongst its own members :—One silver medal to be awarded to the exhibit which the judges may deem most worthy of the distinction ; six bronze medals to be awarded as follows :—(1) Landscape ; (2) figure subjects, including portraits ; (3) architecture (ex teriors and interiors) ; (4) instantaneous ; (5) lantern slides ; (6) enlargements. No special form of entry is required for the competition beyond advising the secretary that it is intended to exhibit, when all pictures coming within the above classi fication sent in to the Exhibition, by members of the Leeds Photographic Society, will be deemed eligible to compete for the above awards, which will be made quite independently of and in addition to any honours gained in the open Exhibition. , proceedings! of Socetes. HOLBORN CAMERA Club. September ith.—Mr. E. H. Bayston presiding. The subject for discussion was “Architecture (Exterior and Interior).” Mr. Fbed. Bbocas opened the discussion on exterior archi tecture, which, he said, might mean a doorway, or a gateway, a house, or Westminister Abbey. It did not appear difficult, but there were certain rules to be observed, among the chief being, “never get directly opposite the subject.” He then showed various photographs demonstrating this axiom. Another was that the camera should be perfectly level. He also gave some excellent hints which experience had taught him during his life as a camera-man. Mr. Golding then gave his experience in taking interiors, which he characterised as the most difficult branch of photo graphy. One of the chief difficulties was the exposure, which would differ in every interior taken. Experience alone would enable one to gauge the right exposure. Slow and thickly coated plates were best. The plate must be backed, or halation would certainly be present in the resulting image. Backing does not do away with halation altogether, but it does certainly lessen the evil. A good backing was a piece of insensitive carbon tissue, preferably black, soaked in weak glycerine, and then squeegeed on the back of the plate. It could easily be stripped off before development and used over and over again. He thought it was a mistake to get the whole of the interior of a church on the plate. A mass of detail is lost in this way, which is, perhaps, the most interesting part of an interior. With regard to exposure, the rule is to expose for the shadows, and not to make it too short. He had found Watkins’ actinometer of some use to him in arriving at the right exposure. Another important matter was judicious and cautious development. He used pyro and ammonia, and commenced with the following :—} grain of pyro, 1 grain bromide, and } grain ammonia to every ounce of developer. When the high-lights begin to show, coax detail out with ammonia, then add pyro, and obtain sufficient density. Ho showed an excellent 12 by 10 interior, illustrating various points in his remarks. Lewes PHOTOGRAPHIC Society. The annual meeting was held at the Fitzroy Institute on Tuesday evening. Mr. J. G. BRADEX occupied the chair, and the attendance included Aiderman White, Councillor Wightman, Mr. E. J. Bedford (hon. sec.), Mr. C. A. Wells, Mr. J. Farncombe, jun., Mr. E. H. Fuller, &c. Mr. George Carpenter was elected a member of the Society. Mr. BEDIORD then read the annual report of the council, which expressed pleasure at the continued prosperity of the Society, and went on to say that four new members had been elected during the year, and three had resigned, leaving forty on the books. Ten ordinary meetings had been held during the year, at which interesting papers were read, and demonstrations given. The council called attention to the quarterly competi tions, which have been established to promote friendly competi tion and criticism of members’ work, and which the council also venture to think would tend to individual progress and improvement. The excursions, taking into consideration the unfavourable weather experienced during the season, had been very well attended. The exhibition of members’ work held on January 28th brought together a very interesting collection of photographs, &c., and was a success, although, owing to the weather, there was a financial deficit. A bookease having now been purchased, the council hoped that a library might soon be formed, and would be glad to receive books or pam phlets from members or others towards its formation. The treasurer’s report was satisfactory, showing a balance in hand of £1 19s. 4|d., notwithstanding a deficit of £3 9s. 9d. in con nection with the exhibition, and also several heavy items in the expenditure, which would not occur another year. The election of officers was then proceeded with as follows :— President—Mr. J. G. Braden ; Hon. Secretary and Treasurer— Mr, E. J, Bedford ; Vice-President—Mr. Tunks ; Committee—
