372 THE PHOTOGRAPHIC NEWS. [August 1, 1862. Ualk in tbe Studio. South London PHOTOGRAPIIIC Society.—The third out door meeting of this society takes place on Saturday, August 2, at Charlton Station, on the North Kent Railway, reached by train from London Bridge at one o’clock. The weather for the two previous appointments has proved very unpropitious ; there is, however, now a fair prospect of fine weather, and we trust the meeting will bo a large and pleasant one. Just on going to press we have received a note from Mr. Wall to say that the meeting will tako place, by permission, in the private grounds of Sir T. Wilson, at Charlton. A dark room, for those who practise the wet process, will be kindly provided by Mr. Davis of Woolwich. Royal Portraits.—We have just seen some of Mr. Jabez Hughes’ charming portraits of their Royal Highnesses the Princesses Helena and Louise, which Her Majesty has graciously accorded permission to be published. The groups especially please us; they are amongst the most graceful and artistic photographs which have hitherto been published of the Royal Family. The Royal Academy.—Lord Elcho has applied for a Com mission to inquire into the present position of tho Royal Academy in relation to the Fine Aits, and into the circum stances and conditions under which it occupies a portion of the National Gallery, and to suggest such measures as may be required to render it more useful in promoting art and in improving and developing public taste. There has been talk for some time of such an institution as a Ministry of Art, and it appears Lord Elcho recommends that some dictatorial power be vested in the Academy. Of this The Times says : — The remedy, so far as we could understand it, would be to give the Academy the direction of our public works, or at least a veto on the designs. If anything of the kind be contemplated by artistic reformers, we would say, ‘ Leave us the old Academy with all its defects—its exclusiveness, its alleged favouritism, its staff of sinecure professors, its inefficient schooling, its dinners, and all that move the indignation of the outsiders. Leave us with the Havelock and the Jenner of Trafalgar Square; leave us with the National Gallery and the Inter- nalional Exhibition, and tho equestrian Wellington, and every other monstrosity of this capital, rather than turn King Log into King Stork, and subject the art of the country to the dictation of an Academy. However eminent and illustrious the members of such a body may be, the power it possesses is sure in the end to repress genius and originality. Such as we are in literature, art, and science, we have become without the aid of academies, and no intellectual evil could be greater than tho foundation of these exotic institutions among us. Uo Coxxesponeuts. Photographic News Almanac.—We have to inform several applicants that the Photographic News Almanacs for every year are now out of print. Agents having any clean copies on hand of the present year will oblige by communicating with the publisher. Agents will oblige also by notifying any stock of back numbers of the Photographic News for the present year, as several recent numbers are out of print. Subscriber inquires, “ If such articles as cloud plates exist, or in what manner clouds are introduced into views ?" We presume, by “cloud plates,” our correspondent means negatives of clouds. These certainly exist, and aid in one of the methods of introducing clouds into photographic land scapes ; we are not aware that they exist at all as articles of commerce, each photographer who uses them producing his ow, and getting such a selection, under such circumstances, as will best suOis pictures. Mr. Max well Lytc adopts this method ; Mr. Annan, of Glasgow, and Mr. Samuel Fry, both, at times, adopt thd same method. The latter gentleman described his plan of operating in our last volume. There are other methods of in troducing clouds, either by using a very rapid process, or shading the sky so as to secure them on the same negative. This method is used by Mr. Wilson and others. Some secure cloud effects by painting carefully on the back of the negative ; these effects may be seen in some of the pictures of Mudd, Bedford, and others. Whichever plan be used, taste, judgment, and care are imperatively necessary. R. A. R —The spots on your prints appear to be due to the albumenized paper, which is probably old, or the albumen possibly stale. Your prints would be improved by more judicious lighting, and a little longer exposure, as they are a little hard. The definition might also be improved. A little care in these respects, and your pictures will be better. 2. The best thing to prepare albumenized paper for water colours is a preparation sold for the purpose by Newman, of Soho Square. Some persons colour on the albumenized surface without preparation, merely using a little ox gall with the colours. But the article we have named answers admirably. R. W. Jacob.—Photographic slides for the magic lantern are transparent positives, produced in printing from a negative on to a collodion film, either by super-position, as by printing on paper, or by what is term camera printing. Various articles descriptive of the process of produg them have appeared in our pages ; we may refer you especially to pp. -! 220, 257, and 280 of our fifth volume; the numbers containing these Pa85 are : Nos. 139,140,143, and 145. In these articles you will find full " structions on the manipulatory details. , , , i D. W. T.—Your difficulty, most probably, arises from excess of iodide o silver in the bath, than from deficiency. Try the addition of a few ounces of fresh silver solution, without any iodide, to the bath, and the sandyee after development, which results in pinholes after fixing the picture," disappear. The white spots to which you refer, as occurring on 8t42 positives, may arise from turbid collodion, or from using glass witharouz imperfect surface. Using a thick collodion with more body will sometimes prove a remedy. A very thin collodion is always troublesome for working the positive process. L. E W.—Similar spots to that you enclose will sometimes arise from some defect, or decomposition, in the albumen. They also arise from hypo toucn- ing the unfixed print, or nitrate of silver touching the fixed, but unwashed, print. We cannot say, certainly, the cause of this especial one. Young Photo.—We have repeatedly stated that there is no method of turn ing a good positive into a good negative ; for if it have been rightly expo^ for the former, it will be under exposed for the latter. It is possible, how ever, to produce a moderate negative from some positives. The best Pla is to wet the film thoroughly, and then apply a solution consisting of iodie one grain, and iodide of potassium two grains, in an ounce of water. After this has remained on for a few minutes, wash and apply a solution of PT gallic acid two grains, and citric acid one grain, in an ounce of distile water, adding a few drops of a 20-grain solution of silver. Continue tn» until the proper printing density is obtained. Operator.—The stain of reduced silver to which you refer, if we rightly U derstand you, is the irregular line of white surface reduction which some times occurs. It generally arises from the free silver coming in contact with some organic matter at the corners of the inner frame of the dar slide. Having these well varnished, and frequently well washed and dried will prevent the evil; or letting the plate rest on pieces of clean blotting paper will often answer the same purpose. If these do not meet yourcase write again explaining more fully. John Beck.—The stain on the mounted print enclosed evidently proceed 3 from the back of the card-board, for, on examining, we find it larger there passing through and slightly staining the surface of the print. There 8 several similar, but smaller, stains at the back of the card, which hax not passed through. Whether it is from some impurity in the card-boar" or accidental contact with some chemical, we cannot say. No. 35.—We prefer the lenses of the best English makers at all timesit French ones. The No. 1 of the maker you name first would mostprobal answer your purpose best. Those of the two French makers you name ar probably, pretty good, but we have no personal knowledge of their qu lities. They will, probably, be of too long focus for stereoscopic Wo giving you very little subject, except at a great distance. Amongst French makers, both the names stand well. B. G. P.—The pinholes are, probably, caused by excess of iodide of silver the bath. See answer to D. W. T., above. 2. A changing box istheneate and simplest means of changing sensitive dry plates without a tent. -2 can get them made for any-size plates. It consists of a plate-box "1 facility for attaching the dark slide, and allowing the exposed plate todro into its groove in the box, and then placing another in the slide, witho admitting any light. . Actinic.—The report on your coloured glass in our next. 2. By all me4he the first mentioned maker. The superiority in quality is quite equal tot difference in price. J. C. L.—The dirty brown tone which you describe is very difficult to aj® with some samples of paper, especially in printing weak thin negatil The best mode of dealing with such a sample of paper, is to use it "l vigorous negatives, use a neutral silver bath, and tone considerably deej than seems necessary, to allow for the loss in the hypo. It is impossl to get fine prints on such a paper, but this treatment will make thebesty it. The sour smell is doubtless due to the addition of acetic acid to , albumen, a custom practised by some manufacturers. It seems to be doubtful utility, as we hear many complaints of its results, the paper g" rally discolouring rapidly after sensitizing. T. N. W.—Negatives cannot be satisfactorily intensified after varnist except by first removing the varnish, a process which we hate sometir effected for the purpose of intensifying. Amber varnish, or crystal more nish, may be removed by benzole or chloroform. Spirit varnish is "ar difficult to remove ; strong alcohol will sometimes do it. A negative sojur nished with spirit varnish may be intensified by using an alcohol 10 tion of bichloride of mercury, followed by a dilute tincture of iodine, there is great risk of the intensity being irregular and unsatisfactor! neet R. II.—A background to roll up may be made of a piece of unbleached ed ing calico, 6 or 7 feet wide, and about 8 feet high. This should be streched on a frame, or against a wall for painting, and when dry may be attasze to suitable rollers. The calico should be sized first with a good gluejqtter and may then be painted grey in oil flatting, or in distemper. If the po be chosen, the method described by Mr. Gulliver on p. 165, Vol. "road TOGRAPHIC News, should be used. For some purposes a cheap Ereysejou cloth, or merino may be obtained wide enough. A blanket if kept WStised of focus makes a good background ; and we have seen a good one imprors fof for occasional use out of the wide brown paper sold by upholster under-lining carpets. mucb M. J.—It is somewhat difficult to advise you from the data given, •-gtipg. will depend upon the actual condition of light, &c., at the time of °p the So far as we can judge, from your description, we shouldLgayPrequire camera in the corner, in preference to directly in front. If VoHiculty 15 further aid please send a sample of the evil produced, or the d be overcome. . you de Honesty Good Policy.—The circumstance you mention, if it be atter, al" scribe, is somewhat inexplicable. We will enquire into the ma endeavour to obtain an explanation. Dage Dages.—The stereographs will be duly noticed as the production arose 01 and Harman. The reference in this column to one name on and inc of a private note on other business arriving at the same time, dentally mentioning the slides. . frst artid F. Vincent.—We are glad you have overcome the difficulty. Po in the present number. Several correspondents in our next.
