RECREATION. 



give me one that will yield great con- 

 trast? P. S. Jones, 



Port Washington, S. C. 



ANSWER. 



No. i. 



Water 16 ounces. 



Oxalic acid -Ya 



Pyrogallic acid I 



Metol (Hauff) Ya 



Bromide potassium 16 grains. 



No. 2. 



Water 64 ounces. 



Sulphite sodium (crystals) 8 



Carbonate sodium 4 



To develop take 



No. 1 .... ■. 1 ounce. 



No. 2 5 ounces. 



Water 2 to 4 ounces. 



In summer, or when soft, delicate neg- 

 atives are desired, use the larger quantity 

 of water. 



The above is a capital developer in 2 

 solutions. Use a tray containing water, 10 

 ounces ; bromide of potassium, 1 ounce, 

 and dip your plate in that 2 minutes at a 

 time as needed during development. You 

 will in that way get more contrast than 

 you ever saw before. — Editor. 



PRINTING ON SILK. 



The silk must be well washed to free it 

 from dressing, then ironed flat, and then 

 immersed 5 minutes in 



Arrowroot 4 grains 



Ammonium chloride. . 4 grains 



Boiling water 1^ ounces 



Hang up to dry, iron again, and brush over 

 with a solution of 



Silver nitrate 20 grains 



Water 1 ounce 



Dry, then print on in the usual way. Wash 

 and tone in any ordinary borax or acetate 

 bath of half the usual strength, and fix in 

 a hypo bath of the usual strength. 



Or an easier method is, after washing the 

 silk, to paint it with 



Uranium nitrate 150 grains 



Silver nitrate 15 grains 



Distilled water jounce 



Methylated alcohol.... 24 ounce 

 Dry in the dark, print deeply, wash in 

 weak nitric acid and then in water and iron. 

 This gives a dark brown image, which can 

 be toned in a weak gold bath. — Photo

THE USE OF BROMIDE OF POTASSIUM. 

 All developers require the addition of a 

 certain quantity of bromide of potassium to 

 keep the whites cleared, and it is most 

 conveniently used in 10 per cent, solution, 

 which is made by dissolving one ounce of 

 bromide in 9 ounces of water. As the 

 quantity of bromide necessary varies with 



the age and dryness of the paper and the 

 purity of the water and chemicals used, it 

 can only be given approximately. It is 

 easily determined, however, by first adding 

 the quantity given in the above formula to 

 the solution and then making a trial test 

 by laying a half-inch strip of Velox over an 

 important portion of the negative and de- 

 veloping and printing it in the regular 

 way. If the whites appear fogged, add a 

 few more drops of the bromide solution. 

 If, on the contrary, the whites are clear and 

 the blacks have a greenish tinge, there is 

 too much bromide in the developer and it 

 will then be necessary to add a little of a 

 stock solution of developer that contains 

 no bromide. To avoid this latter necessity, 

 in adding to the quantity of bromide do so 

 slowly, drop by drop, making tests as di- 

 rected. — Photo Record. 



SNAP SHOTS. 

 Metol-quinol developer will keep a long 

 time after dissolving, if put in bottles which 

 it fills to the neck, the bottles being then 

 tightly corked and placed on their sides, so 

 the bubbles formed by the confined air can 

 not rise against the cork. This prevents 

 oxidation of the developer while in the bot- 

 tles. If the operator wishes to make a few 

 prints at a time and to use the least possible 

 quantity of developer, it is a good plan to 

 have bottles of different sizes at hand. 

 Select each time 1 of such a size as to be 

 entirely filled with the developer that is 

 left, in order to insure a satisfactory con- 

 dition of the developer when it is used 

 again. — Photo Record. 



The Eastman Kodak Company announce 

 another photo competition, in which prizes 

 to the value of $4,000 are offered. One-half 

 of this amount is to be paid in cash, and 

 the other half in Kodaks. Pictures} in or- 

 der to be eligible in this competition, must, 

 of course, be made with Kodaks or with 

 Brownie cameras. Write the Eastman 

 Kodak Company, Rochester, N. Y., for cir- 

 cular giving full particulars, and say you 

 saw the announcement in Recreation. 



Note that when just enough bromide has 

 been added to keep the whites clear, the 

 blacks may have a bluish tinge. If then 

 more bromide is added, little by little, and 

 a test print made after each addition, the 

 tone of the blacks will be seen to change 

 gradually from bluish-black to pure black, 

 and if still more bromide is added, to 

 greenish or brownish blacks. — Photo Rec-

To an amatuer photographer the articles 

 published on the beaver pictures are worth 

 a year's subscription to Recreation.
