MR. FRY’S METHOD OF MASKING. Sin,—My attention being attracted to the leader in last ■week’s News, I at once proceeded to put in practice the sug gestion communicated by Mr. S. Fry. Having a negative that had been intensified with mercury, and which by constant ex posure to the light in- printing had become unmanageably dense, and having some time ago obtained a transparency from it, I placed the transparency over the negative as directed, and was delighted to find that this, like many other suggestions of Mr. Fry, is a really valuable one. Should this hasty note bo considered worthy of insertion or notice in your columns, my desire to serve my brother photo graphers will bo answered. I enclose a print, that you may see the effect.—I am sir, yours truly, 11. C. Oclober 21th, 1868. [The print enclosed is an admirable illustration of right ap plication of the principle of masking referred to ; and a round, delicate, and well-modelled print has been obtained from a hard negative.—Ed.] Dear Sik,—The letters of “R. F.” and “Zeta” are both founded on erroneous premises. Each assumes, in the first place, that my invention for masking negatives is theoretical only, and also that it is intended merely for the improvement of had or too hard negatives. First, then, I have used it in my ordinary portrait practice for about eight months with gre t advantage and high appreciation from the public, and it has created an entirely new branch of business with me, although no announcement of any specialitfi has ever been made. If your correspondents will write to me, a specimen of the result shall be sent to each. I think I have shown that this is a simple, practical business matter. Second, with regard to the negative, I find the finest nega tives' are most amenable to this method. The difference be tween a print before and after treatment is very great. Take a small transparency of a negative, and a paper print from the same, the difference in detail is enormous ; this experiment exactly illustrates the difference in value between a plain print and one treated according to my method. Should any further information be necessary, I shall be happy to afford it. Specimens of the results of this method of working, with the negatives and also the transparencies employed, will be exhibited nt the exhibition next Tuesday, at Conduit Street. 1 am not a producer of specimen pictures, and therefore those shown will bo the results of ordinary business work. The application of the transparency at the proper place and time is as simple as possible, and is readily effected as an ordinary detail of printing. As a matter of private opinion. I never by any chance entrust printing of negatives to any but thoroughly qualified persons who have undergone a long and careful training under my own eye and according to my own notions. I do not believe in letting just any one do it.—Yours faithfully, Samuel Fry. Surbiton, November 2nd, 1858. TO STRENGTHEN VARNISHED NEGATIVES. DEan Sir,—The best method of giving additional density or printing power to varnished negatives which may be some what wanting in these qualities has sometimes been discussed in your columns ; but a plan I have lately adopted with much success, and which, in my hands, is simple, efficient, and does not destroy half-tone, I have not seen mentioned. I claim for it no originality, for it is almost too simple not to be well known and often practised. I seldom have to alter any negatives, but occasionally it is desirable to modify them ; and when I err in intensifying, it is generally on (I fancy) the safer side of not carrying it quite far enough. A ready method of adding in tensity to a varnished negative is no doubt a valuable reserve power to have at command. A varnished negative that needs strengthening is to bo treated slightly with spirits of wine, but not absolute alcohol, for that dissolves the film, as does also the impure methylated spirit. When dry, the surface will be dull, and the intensity of the negative much increased. 1 enclose two prints illustrative of the effect; the one taken from the negative before alteration, the other after. The other carte portrait—the little girl sitting—is a specimen of my gold and mercury intensifying process pure and simple. It is a very delicate intensifier, and in the case of a thin nega tive should be followed by a weak solution of iodide of potas sium. These hints are at your service if you think them worth pub lishing in the News.—Yours truly, 0. T. Winter. Cheltenham, N ovember 2nd, 1SG8. [The difference between the prints taken before and after the treatment described is marvellous. Before treatment, the negative yielded a poor, feeble print; after treatment, the print obtained is brilliant, round, and vigorous, without loss of delicacy. The print from a negative intensified by the gold and mercury solution, which Mr. Winter has before described in cur columns, is very admirable.—Ed.] PROPORTION OF SALT IN ALBUMINIZED PAPER. Dear Sir,—I have often been struck with a singular pro pensity in the tradesmen I may happen to deal with, to know a great deal more about what I want, or what 1 should want, than I know myself. My tailor tells me, when I remonstrate with him for making a garment contrary to orders, that “ it is worn so.” My butcher replies to a remark that the joint is too fat, that “ the fat is the best part of the meat and so on with legard to almost everything used in domestic life. Well, sir, in these matters I grin and bear it; but when the same practice is applied to the tools or materials of my profes sion, I feel disposed to make a stand against it. At one time my optician met my request for certain improvements in lenses by a brusque reply to the effect that photographers must im prove their processes, as the lenses were perfect. Mais nous avons change tout ccla. But now albuminized paper makers seem disposed to adopt the same tactics. At the North Lon don meeting Mr. Hart complimented photographers by saying that nine out of ten of them could make no use of the know ledge of how much salt was used in their albuminized paper, us though that were a justification of the practice of with holding the information from those to whom it was valuable. Mr. Bovey goes further still; and because Mr. Cherrill has ventured to wish for some uniformity in the quality of paper, and some knowledgeof the amount of salt used, to guide him in making and strengthening his nitrate bath. Mr. Bovey tells him that he is incompetent and inexperienced in printing. I fancy that is not true ; but if it were, it would only be a stronger reason for supplying information to aid the inexperienced printer. Now, sir, I respect and esteem both Mr. Hart and Mr. Bovey very highly. Mr. Hart has often published valuable sugges tions in your pages. Mr. Bovey’s practical articles are full of valuable matter; he is only dangerous when he loses his head and gets into wordy rhapsodies. I have used the paper of both gentlemen, and know it to be excellent. But is it not too bad that I cannot ask a reasonable question without being told by one that I cannot make any use of the information I seek, and by the other that I am incompetent because I ask it ? I think, on reconsideration, that both these gentlemen will feel that they have been less considerate to photographers than is wise, polite, or politic.—Yours, sir. One who does not LIKE to work in the dark. PORTRAITURE “ ON APPROBATION.” Sir,—My object in writing to you is to protest against the custom which appears to be creeping in of taking portraits on approbation. People come and occupy your time for an hour or two, as the case may be, pay nothing, and request that " proofs may be sent.” They reject the whole as “ not approved,” although as photographs they may bo unexceptionable ; and, when expostu lated with, say “it is the practice among other respectable photographers, and that of course they cannot think of paying for portraits they do not like. This has happened to me more than once of late. Truly photographers are their own worst enemies.—I am, sir, yours obediently, George Downes. Bedford, October 2Sth, 1868. THE PHOTOGRAPHS OF THE LATE ECLIPSE TAKEN IN INDIA. Sir,—With reference to an article that appeared in your impression of the 23rd. ultimo, entitled “ Failure of Photo graphing the Eclipse in India,” in which you have unjustly
