May 7, 1869.] THE PHOTOGRAPHIC NEWS. 227 The Method Adapted to Printing from Nature by Means of Gelatinous Ink. A photographic negative is taken from nature or from a painted original, and then, ‘according to the above-described process, a metal plate is prepared in which there will be con cave spaces corresponding to the shades of the original, which concave spaces will be deeper the stronger the shades are. The metal plate is covered with a thin layer of benzine or collodion, and when it is dry gelatinous ink is poured on it. The paper is then placed on the plate, and they are subjected to equal and strong pressure, in order to squeeze the ink out of the elevated portions. When the ink is quite dry, the plate is taken out of the press, and on the paper will be found an image resembling a photograph. For durability it is well to add to the gelatin ous ink a small quantity of alum. A PANORAMIC CAMERA. BY JOSEPH RAINE. Tins invention, for obtaining panoramic pictures, received provisional protection only :— My invention consists in dividing the camera into two or more equal parts by means of a division so constructed as to produce a picture with a soft or vignetted margin, and an arrangement by means of which the camera, after one view has been obtained, may be moved through such a degree of space as to cause the margin of the second picture taken so to superimpose and unite with that of the first as to yield a pan oramic view by the junction of the several pictures thus obtained. The method I employ to effect this softening of the margin consists in having a divisional partition in the camera, which division is composed of a metal or other band with serrated edges, and passing over two pulleys, one at the top and the other at the bottom of the camera. The width of this band is so adjusted that when a lens is fitted into each division of the camera and a sensitive plate is exposed when the camera is pointed at any uniform body, the serrated edge of the band, which must be moved by means of a handle attached to the axis of one of the pulleys over which it travois, shall so soften the edges of each picture as to produce a continuous effect of lighting. To apply this for taking a panorama the camera is made to rotate upon a table in such a manner that after a view has been taken on one portion of the plate by means of one lens, the camera is rotated a certain previously determined distance and the second picture is taken. By the arrangements now described these pictures will form a continuous pano ramic view. The division may be so formed as to be easily removed, when the camera may be used for taking views or portraits of the ordinary kind. Instead of having a separate lens to each division of the camera, ono Ions only, fitted on a sliding front, may bo used. CORRECTING DISTORTED IMAGES. BY JAMES ALEXANDER SMITH. The alleged invention described in the following provisional specification is one of the very few which tho patent autho rities decline to protect, and even provisional protection was refused in this instance :— This apparatus enables the manipulator to correct or avoid an inaccuracy in the exis ting mode of taking photographic i mages or photograms, by which foreshortening, and perspective, and the relative proportion of parts to each other are falsified, exaggerated, or distorted in photographic images or photograms as now and hitherto taken, and which inaccuracy is occa sioned by tho sensitized plate, or surface on which tho image or photogram is taken, being a flat transverse surface, intercepting a cone of diverging rays at ail the inequalities of distanice from the focus of the camera lens as now in use, at which tho various parts of the flat base of a cone are unequally distant from its apex. Tho means by which I correct this cause of inaccuracy in photographic images or photograms is by inserting a lens or lenses between the focus of tho camera lens as now in use and the sensitized plate or surface on which tho imago, photogram, or impression is received and taken, and thereby, or by other optical means and appliances suitable for that purpose, re directing tho actinic rays or rays of actinic light into parallel tays, or as nearly so as may be, or into such other direction as, after the rays have passed through and diverged from the focus, will enable the imago to be projected on a flat sensitized surface with its parts in the due or desired relative proportion to each other, or in more correct relative proportion than has hitherto been the case. I also propose to insert or introduce into the camera a diaphragm or opaque screen, with a small aperture in it, for the purpose of intercepting, by said diaphragm or screen, all, or as nearly as may be all, actinic rays which do not con verge to or pass through the focus aforesaid, and thereby securing, as far as may be, the actinic efficiency and homogeneous purity of tho colours or coloured rays proceeding from objects photographed, with tho view of producing coloured images or photograms of such objects. orxesponence, EXCLUSIVENESS AMONGST PHOTOGRAPHERS. Sir,—No disinterested person can read the various photo graphic journals for any length of time without being forcibly struck with the want of charitable feeling exhibited by certain professors towards their humble brethren of the art. Every new thing that comes up is prophesied and hoped to be too difficult of accomplishment by the cheap- and-nasty school, &c. It was the case with the cartes, the cabinets, and enlargements ; and now Mr. Sarony’s trans parency is to .be a regular poser—it will require such a vast amount of care and skill, and the developer will have to be mixed with such a large amount of brains, an article apparently monopolized by the gentlemen referred to. Meanwhile, the plebeians of tho art jog along quietly, and no doubt get a good scraping off the bone, while the other gentlemen are struggling for the shadow. I observe, with pleasure, that those gentlemen whose works bring them pro minently before the public, and who are really the upper ten in photography, show more consideration towards their inferiors, by never offensively alluding to them, whilst all may gain both pleasure and profit from their works and writings. The insertion of this in the Photographic News will greatly oblige, sir, yours respectfully, A Subscriber and Reader from the First. Ualk in tbe Studio, The Photographic Society of London.—A new and re vised list of members of the Photographic Society has been issued, from which it appears that the number is now 225, after the elimination from the books of the names of those who, by non-payment of arrears or other cause, had ceased to be qualified for membership. Professional Photography in New York.—A paragraph in a recent number of Humphrey't Journal suggests a gloomy prospect for photographic portraitists in New York. It says : “ Coming down Broadway the other day we noticed a bill on the store occupied by C. D. Fredricks and Co., with the sig nificant words, ‘ To Let, First Floor and Basement.’ These gentlemen have occupied these premises for eight years. Last year they let out half tho first floor; now they will let the whole first floor and tho basement, and occupy somo of the lofts th emselves. ‘ Straws show which way tho wind blows,’ and this movement on tho part of Messrs. F. and Co. shows that the picture business in New York is at a low ebb.” Carbolic Acid as an Antiseptic.— Pagliari, an Italian chemist, says tho Artizan, has invented a kind of paper wherein carbolic acid is so thoroughly incorporated that the paper, when used to pack animal substances therein, preserves tho same in a fresh state without salt or any curing whatever. Probably its use for packing albuminized paper might prevent the change indicated by an unpleasant smell to which, :n damp weather, albuminized paper is subject.
