120 THE PHOTOGRAPHIC NEWS. [February 13, 1891. bichromate bath,or removed therefrom, the current is started or stopped. The duration of the light with one filling of the cells is only three hours, and the zincs are very rapidly dissolved. For ordinary work, then, this instrument will not be of much use, but there are cases where it will render certain service. Use of Sulphite of Soda in Development.—The indiscriminate use of sulphite of soda has, with good reason, attracted the attention of M. Reel, who says that a developing solution containing ten per cent, of this salt may dissolve a film of bromide of silver. Tt is necessary, therefore, to limit the quantity to what the plate will bear without evil effect. It is true that reduced silver retards this action. M. Reel therefore advises the use of a developer suffi ciently energetic to produce an immediate effect, so as to oppose the solvent action of the sulphite of soda. Chloro-bromide Plates.—Messrs. Marion, Son, & Co. showed very fine results obtained upon their new chloro bromide plates for transparent positives for lantern slides, &c. The plates are slower than those containing gelatino- bromide, but they are quicker than' chloride plates, so that they may be usedin the camera for enlargements and reductions, whilst yielding perfect transparency in the clear portions. Neto Pattern Pressure Frames.—Messrs. Poulenc Freres exhibited pressure-frames of a new pattern. The illus trations will give a complete idea of them. The catches of the press may be opened in both directions, and, consequently, allow the image to be seen in all its length and all its breadth, which cannot be done with the ordinary frame. This pattern will certainly replace the old type. Micrographic Lantern Wes.—Amongst the many lantern projections exhibited, those by Messrs. Lumiere and Son, of Lyons, were especially remarked. They represented the embryonic condition of the fowl from the first to the end of the third day. The photographic transparencies, printed in various colours by imbibition, are of remarkable delicacy and purity. Direct Carbon Printing.—Mons. E. Vallot has made some happy experiments in producing direct impressions by carbon printing. The print is made in such a way that it is developed without transfer and without reversal of direction on the prepared paper itself. The process is analagous to that of M. Artigues—published in the Photographic News in 1889, p. 517. The latter not having disclosed his method, M. Vallot has been experi menting in the direction indicated, and his first results are very satisfactory. No doubt, with the manipulative skill that M. Vallot possesses, he will achieve remarkable success. The PHOTOGRAPHERS’ Benevolent Association.—At the meeting held on the 9th of February (Mr. Bedford chairman), Mr. Farrington was elected auditor ; one grant was considered and refused ; the report and balance sheet were adopted ; and the annual general meeting was fixed for the 27th inst. PHOTOGRAPHY IN MANCHESTER. The Photographic Exhibition in Manchester. THe Manchester Amateur Photographic Society held an exhibition of the work of its members in the Athenum at Manchester on Monday, Tuesday, and Wednesday this week, and in the evenings there were lantern dis plays, attended on each occasion by about 700 persons. Among the photographs on view bromide prints were most numerous, perhaps aristotype ranked second in number, platinotype third, and ordinary silver prints fourth. Among the best exhibits are those of Mr. G. Wheeler, who lias a screen to himself covered with views of Holland, and of scenes near Manchester : in the latter region he has detected, with an artistic eye, some pretty “ bits ” where nobody would expect to find them. Some views at Oberammergau by Mr. Lamond Howe, some of which he furnished to Mr. Stead, are interesting. The Rev. II. J. Palmer had a great screen covered with enlargements, chiefly of Swiss views ; he also exhibited photographs of French cathedrals. Mr. Palmer was formerly president of the Liverpool Amateur Photographic Association ; he is now a vice-president of the Manchester Society. Miss Twist exhibited some excellent landscape photographs of small size, and by different processes. Mr. T. Glazebrook exhibited some good cloud subjects and fishing scenes; one of them represented a fisherman on the Wye, standing with his coracle on his back, and holding a fish in his hand ; the title of the picture was, “What does it weigh?” Amongst Mr. H. Wade’s exhibits was a sunset scene of an artistic nature ; it was also exhibited on the screen on Tuesday night by means of the lantern, and warmly applauded by those present; he had taken the view with a hand-camera. Some auto type enlargements from quarter-plates by Mr. .1. Daven port were of excellent quality. Mr. J. W. Wade exhibited a platinotype print of “The Wounded Amazon,” taken at the visit of the Photographic Convention last year to Eaton Hall; it had been printed by the cold process, and was of good quality ; the same exhibitor placed on view a photograph of Chester Cathedral. Mr. G. A. Rigby exhibited some nice platino- types, expecially Exeter Cathedral. The following description of the Exhibition is from The Manchester Guardian of last Tuesday: — The annual exhibition of work executed by members of the Amateur Photographic Society was opened to the public at the Athenum last evening, and will remain open till Wednesday night. In photographic circles, an advertisement of a camera is well known in which occur the words, “You have only to press the button ; we do the rest,” the meaning of which is that the so-called photographer has only to hold or fix up his camera before a view or object, to “press the button,” take out the plates when he returns home, send them to be deve loped to the place from whence they came, and in due time receive back a batch of negatives or spoiled plates as the case may be. If any of them be successful exposures, he may get a few beautifully printed and mounted specimens. Such button pressers the Amateur Society, we are glad to say, does not acknowledge as photographers, and the work shown on its walls is not of this class, but is the genuine work of the person whose name it bears, except so far as the manufacture of the sensitive plates is concerned ; nowadays, it may be said, no one makes these for himself. Enlargements are an exception to the general rule, and some of those shown are original only so far as the negative is concerned, the actual enlargement being made professionally ; enlargement is, however, so much a mechanical matter that a picture may properly be spoken of as by the person who made the negative.
