At a recent meeting of the Photographic Society of Great Britain Mr. Beard exhibited a very simple and well- designed clip, by which a small camera can be conveniently and expeditiously attached to a stile, fence, or other object, and by the use of which the photographic tourist may often dispense with the necessity of taking out the. inconvenient and difficult-to-be-disguised tripod. B A is a screw-cramp, which may be brass, but should be made, by preference, of malleable cast-iron. Upon the screw-cramp B A there are two studs, as shown at D and C. while upon either of these can be fitted a socket-piece E F, provided with a hinge at E, and a small table, F, upon which table the camera is fixed by the thumb-screw. The object of providing the two similar studs C and D is obvious, as circumstances may give the worker little or no choice as to whether C or D will be directed outwards. If intended for a small camera, Mr. Beard’s clip may be made very light; in fact, it need not weigh so much as the lightest tripod now constructed; but we would suggest that there is a direct advantage in making the span or gape of the screw-cramp as much as nine inches, for under these circumstances it can be fastened upon the top or side of the ordinary garden or boundary wall. Many cases suggest themselves in which such a clip as that of Mr. Beard may be of service. A passenger in a railway carriage may keep his camera ready fixed on the frame of the window, so that at any moment he can slue the apparatus round to the right point of the horizon, by turning the socket round on the stud C. Similarly a rider in a road-carriage or cab may keep his apparatus ready for immediate use ; or the passenger on the top of an omnibus may attach the camera to the rail in front of him. The indoor photographer or the amateur portraitist will have but little difficulty in finding articles of furniture to serve as convenient supports ; while for views taken from the window of a building—let us suppose the hotel at which a tourist is staying—the clamp of Mr. Beard is all that could be wished. In connection with this use of the apparatus, it may be mentioned that very curious pictures may sometimes be taken from the top of a high building by looking directly downwards with the camera, especially when an instantaneous view of a crowded thoroughfare is taken, THE INTERNATIONAL EXHIBITION AT NEW ORLEANS. The photographic exhibits are gathered together in the Mnsic Hall, but it is scarcely necessary to remark that very many objects of no inconsiderable interest to the members of the photographic fraternity are to be found in other departments of the World’s Fair. At this early stage one cannot say very much, as com paratively few exhibits are fully arranged ; it being ex pected that several weeks must elapse before there is even a general aspect of order and final arrangement; but it is satisfactory to find the photographic arrangements well ahead in comparison with the rest. The Music Hall, which is very centrally located, has three extremely convenient and well-lighted galleries, and of these, two—that on the south and that on the west— are devoted to photography, while the north gallery con tains illustrations of the various methods of reproducing the work of the artist or the draughtsman. Among those whose work deserves especial mention may be mentioned Guerin, of St. Louis, and Gutekunst, of Philadelphia; the panoramic pictures exhibited by the last-named gentleman far surpassing anything which he has previously exhibited in this line. As our readers pro bably know, Mr. Gutekunst’s are made from several nega tives, but printed on a single sheet of paper, the joins being disguised by so managing the printing that there is a slight loss of sharpness at the line of junction. So effectual is Mr. Gutekunst’s method, that one has to look very closely to find any trace of a join. Taking the picture exhibits all round, the various branches of photographic work are well represented, the show of enlargements and photo-mechanical work being good; but, as far as we know at present, carbon printing is unrepresented. Apparatus is shown in abundance, but there is not yet very much calculated to be novel to the readers of the News. Among those few Englishmen whose work is to be found at New Orleans, may be mentioned Mr. F. York and Mr. H. P. Robinson, but some more arrivals of English work are expected, and as the arrangements become more complete, we shall have more to say. ON THE CHOICE OF LENSES FOR PORTRAITURE. “That head was taken with a portrait lens twelve inches diameter,” remarked a friend of ours one day, pointing to
