use, add Solution II. to Solution I. in 

 equal quantities. 



ANSWER. 



i quart ; glycerine, I ounce ; soak 5 minutes 

 after washing and pin up film, right out of 

 soaking solution, by its 4 corners. — Editor. 



The formula says to add 8 ounces of 

 water to 2 ounces of glacial acetic acid. 

 That gives 10 ounces of dilute acid. To 

 that, add 44 grains of nitrate of uranium. 

 Then mix 50 grains of red prussiate of 

 potash in 10 ounces of water. Bottle each 

 separately and label A and B. Use one 

 ounce or more of each to intensify nega- 

 tives and throw away this mixed intensi- 

 fier after use. Separately they keep, but 

 not mixed A and B. — Editor. 



TRANSMISSION OF LIGHT 

 Following is a good way to experiment 

 with the effects of the selective transmis- 

 sion of light produced in the negative, or 

 in other words the results of absorbing 

 partly or wholly one or more of the 3 

 colors, red, green and violet, which go to 

 make up the light that reaches the plate. 

 Place in a clear hypo or hypo-chrome alum 

 solution a plate which has been spoiled in 

 exposing or any plate in which there is no 

 free silver. A new plate is best. Leave 

 until every trace of the silver and bro- 

 mium salts has disappeared. When the 

 opaqueness has vanished the operation is 

 about Ya, completed. After thoroughly 

 washing out the hypo dry carefully. 

 When the gelatine is hard lay the plate, 

 film down, on a clean filter or blotter and 

 cut it with a diamond into squares of a 

 size sufficient to cover the *lens. These 

 small plates will readily assume the color 

 of any solution into which they are placed. 

 Do not use a solution that will leave a 

 crystalline deposit on the film in drying. 

 Procure some of the aniline colors and mix 

 them to suit yourself. Varied results will 

 be obtained by combining one or more of 

 the screens or by only partially covering 

 the lens during exposure.

Is E. W. Newcomb's spotting medium, 

 mentioned in March Recreation, used for 

 retouching negatives? Where can I ob- 

 tain it? What will keep films from roll- 

 ing? 



My husband and I enjoy Recreation 

 greatly, and find much useful and inter- 

 esting reading matter in it. 



Mrs. R. E. Sumner, Ludlow, Mass. 



ANSWER. 



No, Newcomb's Ideal spotting medium 

 is not to retouch negatives in the sense of 

 smoothing out faces. It is to fill in holes, 

 scratches, etc., in both negative and 

 print. You will find the soaking solution 

 given in Eastman's instructions the proper 

 thing to keep films from curling: Water, 



Those who are accustomed to work the 

 carbon process, know that when the same 

 warm water has been used for developing 

 several carbon prints, the dissolved gela- 

 tine has an unpleasant, tendency to work up 

 into a froth by the inevitable splashing of 

 the water. To skim off this froth is only 

 to find it replaced a few moments after- 

 ward. The following suggestion meets the 

 case : Take a piece of common yellow 

 kitchen soap, and pass the moist hands over 

 it 2 or 3 times, just enough to get a slight 

 lather. This, when mixed with the water, 

 dispels all gelatine froth as though by 

 magic and no harmful effects follow. A 

 slight trace of soapy lather will counteract 

 a large quantity of gelatine froth. — The

What will prevent ferrotype plates, that 

 are used for squeegeeing, from adhering? 

 D. B., Plymouth, Pa. 



ANSWER. 



Make the following waxing solution and 

 when your ferro plates are cleaned and 

 polished drop a few drops on each and 

 rub around vigorously with a woolen cloth 

 until an almost unperceptible coating is se- 

 cured. Then squeegee your prints on and 

 they will never stick. Repeat at each use of 

 plates.

Will you kindly give me a little in- 

 formation in regard to coloring photos? 

 I mean, to take the print after it is made 

 and color the dress, hair, eyes, etc. What 

 kind of colors are used, and what is used 

 to soften the print, so it will take the color? 

 How are colors applied, etc.? 



W. W. Noble, Yazoo City, Miss. 



ANSWER. 



Use Marshall's electric colors and his 

 medium to apply before coloring, so the 

 color will spread. The colors and full in- 

 structions are to be had of A. G. Marshall,
