The Optical Magic Lantern Journal (May 1891)

108 «©The Optical Magic Lantern Journal and Photographic Enlarger. DurInG a part of last month the Duke of Newcastle’s new church in Clumber Park has been the scene of some rather unusual proceedings. A series of ‘“‘ magic lantern services’? was held in the church, the lantern being worked by the Duke’s labourers, and the chaplain accompanying it with a “ narrative.” + » ? Messrs. NEwTon & Co. have recently completed a fine lantern for the Camera Club. We learn that it is pronounced perfect in all respects. oo ® Wir reference to the article on Fantoccini slides in our last issue, we have to state that Messrs. Perken, Sons, and Rayment are now sole agents for this ingenious and amusing slide, which will be ready in a month. ; * * 3 Durinc the visit of the British Association, the Cardiff Photographic Society will hold an International Photographic Exhibition from August 12 to 26. Lantern slides sent for competition must be marked with the title ; and the entrance charge for each set of six will be one shilling. All winning slides must be presented to the society. * * * In about a fortnight Messrs. Theobald & Co. will have ready a set of coloured engravings of the various rooms in their new premises at Farringdonstreet, E.C. * * ® MEDALS were awarded for lantern slides to the following competitors at the Crystal Palace Exhibition :—Professionals : G.

Watson and Sons, 313, High Holborn, is named after its inventor. An excellent feature in this camera is that one is enabled to see by looking at the finder, when an object is sharply focussed. This will be understood by the following description of the internal arrangement of the camera. . The front containing the lens is capable of being racked in or out by turning a small thumb screw situated underneath the camera. The exposing shutter is placed at an angle of 45 deg., midway between the lens and the plane at which the sensitive plate is held. On this shutter or flap is a mirror which throws the image from the lens to a focussing glass on the upper part of camera (see cut). As the distance from the lens to the sensitive plate is precisely the same as that from lens to focussing glass via the mirror, it follows that when an object is sharply depicted upon the finder, it willalso be absolutely sharp at the exposing lane. : Two methods are provided for making the exposure —that for time exposures being operated by a cord on top which lifts the flap spoken of, and it returns to its position by means of a spring as soon as the cord is released ; instantaneous exposures are operated by a trigger action from underneath. A small finder is situated at the bottom of the camera, which enables it to be used inverted should it be desired that a greater exposure be given to a dark foreground. The lens (rectilinear) is of short focus and good covering power, and has an iris diaphragm. The camera is made to hold plates or a film roll holder, and the fittings for either can be changed in a few seconds. The plates (twelve) are contained in sheaths ; a turn of a knob at the end causes the plate at the back to rise, and also records its number ; a flexible reservoir being over the plate, it can then be lifted slightly and pushed down at the exposing plane. To change this attachment for a film holder, a vulcanite slide is placed in front of the plate, when the whole reservoir may be lifted out and the roll bolder substituted. By providing oneself with several reservoirs, a large number of plates may be exposed without necessitating the use of a dark room. These reservoirs are attached by a secret catch, so that there is little fear of meddlesome fingers opening the camera should it beat any time left in the way of such. The various actions work with smoothness and precision. The camera is covered with leather, and has nickel fittings. 10: A SHORT time ago I lent my hand camera to a friend, and now he is like the child in Pears’ soap advertisement—he won't be happy till he gets one.—J.
