tide," is the most admired picture I ever 

 made. 



I have found by experiment that by 

 full moon with the plate named, whiph 

 is very sensitive to yellow light, and 

 f 22 I can get these pictures every time. 

 I print in platinum and generally dip the 

 print in weak bluing after developing 

 and washing. W. P. Oxford, in the Photo-

SNAP SHOTS. 

 What causes transparent spots on my 

 negatives after developing? Can I get an 

 extra bellows made to fit in the back of a 

 Korona Series 1, to slip in where ground 

 glass is? Have any readers of Recre- 

 ation any negatives of the Pan-American 

 for sale; 4x5 preferred. 



Jos. B. D., Allegheny, Pa. 



ANSWER. 



Bubbles cause transparent spots on nega- 

 tives. If you keep a tuft of cotton in the 

 tray with the developer and rub the photo 

 gently with it soon after it is wet you will 

 do better. Use fresh cotton each day, of 

 course. A smart rap or 2 on the end of 

 the tray while develooing is also good. 



Gundlach Optical Company, Rochester, N. 

 Y., can tell you about bellows for their 

 Korona cameras. You can obtain prints of 

 all the exterior views of the Pan-American 

 Exposition, with clouds in all, from E. W. 

 Newcomb, Bible House, New York; 25 

 cents each, unmounted, or for less price in 

 quantity. — Editor. 



Have you a formula for printing and 

 toning on silk? 



E. N. Stephenson, Moline, 111. 



ANSWER. 



Wash the silk in warm water. Float 

 on following bath 2 minutes : 



Salt 10 grains 



Water 1 ounce 



Ammonia 15 drops 



Hang up to dry. Sensitize by floating 

 on following bath: 



Silver nitrate 150 grains 



Water 1 ounce 



Dry and mark through back. Print deep 

 and tone in any good toning bath, say 

 water, 8 ounces ; gold, 1 grain, in 1 ounce 

 water, to which add 5 to 8 grains of bi- 

 carbonate of soda. 



Fix in hypo soda 1 ounce, water 8 

 ounces. Wash well and dry. — Editor. 



Can you, or any of your readers, tell me 

 how to obtain a good negative from a 

 moonlight exposure? I am most anxious 

 to get a good moonlight print, and should 



like to know what exposure and dia- 

 phragm to use in order to obtain the best 

 result. 

 Arthur L. Owen, Keating Summit, Pa. 



ANSWER. 



When the moon is full, you can take a 

 good picture of a light object with your 

 lens at full opening in about 10 minutes. 

 If you stop down to 16, you would better 

 give 20 minutes. This will fully time 

 white houses or other light subjects. In- 

 crease according to darkness of subject as 

 necessary. A dark colored house should 

 have full illumination at 10 p. m. and an 

 exposure of nearly an hour on an iso plate. 

 Let the lights in the house be lighted 

 about- 5 minutes, then turned out if you 

 wish the windows to show. — Editor. 



The following formula has been used 

 successfully for the preparation of a 

 photographic basis on ivory for miniature 

 painting. 



Silver nitrate 3 parts. 



Uranium nitrate 30 " 



Alcohol (Atwood's patent)... 1 00 " 



Water 10 " 



Make up this solution and apply to the 

 ivory with a soft brush. Dry the sensi- 

 tized surface so prepared in the dark and 

 afterward print by contact in daylight. 

 Fix the picture printed by immersing in 

 water acidulated with nitric acid. Rinse 

 in clean water and dry. 



It is essential that the surface of the 

 ivory be absolutely clean; the least trace 

 of grease or moisture will cause patchy 

 prints. — Professional and Amateur Pho- 

 tographer. 



I am glad to see in March Recreation 

 that brother Murray is interested in forming 

 a Recreation camera club. I hope we can 

 pe 1 this good work started. It will be of in- 

 terest to all who are lovers of photography 

 and of Recreation. The photo department of 

 Recreation is of great benefit to amateurs. 

 I have learned more from it than from 

 photographic periodicals, of which I read 

 many. I am in favor of forming a club of 

 readers of Recreation, to be known as 

 Recreation Camera Club, and suggest that 

 each member give a small fee, to help the 

 good work along. Some day let us have a 

 convention. I hope other readers of Rec- 

 reation will give their ideas and sugges- 

 tions in future issues of the maeazine and 

 that we may soon organize the club.

After many experiments and failures, I 

 have come to the conclusion that the best 

 outfit is the plates, pyro developer, Dekko 

 and Dekko developer put up by the East- 

 man people, which makes 4 ounces of de-
