 The Camera and Dark Room. 



SEVERAL ANSWERS. 

 I have just received a No. 4 Poco 

 camera. It is the proper size for all ama- 

 teurs although a picture of this size can be 

 taken with a larger camera. I have been 

 using a smaller camera, but am now satis- 

 fied that I am making better pictures for 

 less money. I use eikonogim developer. It 

 develops thin negatives. What is the 

 cause? Please tell me what developer to 

 use for making flashlights. What is the 

 necessary charge of flashlight powder to 

 use in a room 12 by 18 feet? Have you 

 formed any camera club yet?

ANSWER. 



Eikonogen gives good detail, but not 

 enough density as a rule. I should certainly 

 use % as much hydroquinone with it as the 

 quantity of eikonogen. Even then the pyro 

 developer advised by the maker of your 

 plates is best. Pyro beats everything and 

 if it does stain the fingers a trifle one can 

 avoid it by using rubber finger tips, which 

 are inexpensive and satisfactory. 



Twelve feet away from your subject you 

 may use 60 grains of flashlight powder if 

 you stop the lens way down. With a large 

 stop 40 grains are enough. Two Eastman's 

 flash sheets will serve, also, and these 

 are cleanly and efficient. Editor. 



MOUNT PRINTS DRY. 



Make a thin solution of pure white glue 

 and brush it over the card in the place 

 where the print is to go. Lay the print on 

 the card and rub down with your thumb, 

 •dry, starting at the centre and working out. 

 When near the edge lay an old negative on 

 the print and then lay a weight on to hold 

 it down until you get another print ready. 

 In this way a large number may be mount- 

 ed ki a short time. Do not put on too much 

 glue or the face of the print will get 

 sticky. There will be no curling of prints 

 on the edges, and the cards do not warp 

 as if mounted wet. 



To polish glossy prints take some old 

 negatives and clean off the backs as much 

 as possible. Rub the negative with a piece 

 of wax candle sufficiently to cover the 

 plate, or to cover any dirt that may not 

 come off. Rub well with a piece of cloth, 

 then lay the wet print face down on the 

 glass, rub down tight, press out all sur- 

 plus water and air, and let it dry thorough- 

 ly. Prints dried in this manner have a 

 beautiful polish and will not stick to the 

 glass. The prints, while on the glass, may 

 be brushed over on the 'back with a thin 



PYRO DEVELOPER. 

 In November Recreation an item re- 

 printed from The Professional and Ama- 

 teur Photographer gave the following for- 

 mula for pyro developer: 



Water 64 ounces 



Carbonate potash 2^2 ounces 



Sulphite of soda crystals (hy- 

 drometer test 40) 10 ounces 



This solution to be used with 16 grains 

 of dry pyro. 



In making up this my druggist says the 

 whole solution, water, potash and sulphite 

 of soda crystals, should test 40 by hydrom- 

 eter. I thought it meant that the sulphite 

 of soda crystals, 10 ounces, fluid, should test 

 40 by hydrometer. The latter construction 

 requires much less of the sulphite of soda 

 crystals than 10 ounces by weight. Which 

 is right? I like the articles on photography 

 and enclose $1 for renewal of the sub- 

 scription of Geo. B. Hopson, my son. 

 C. R. Hopson, Elgin, 111. 



ANSWER. 



The druggist is correct. The whole so- 

 lution should test 40; but still better, the 

 sulphite should test 60 and the carbonate 

 of potash 40. Pyro seems to be greatly in 

 excess for ordinary use if not diluted. —

CHEAP TRAYS. 



Your photo department in Recreation is 

 more and more interesting every month. 

 With the kindness you show us amateurs 

 I do not know why we do not make the 

 department as interesting as the gun 

 cranks make their side of the house. Sure- 

 ly they depend on us for views. 



Let me suggest a cheap tray for all pur- 

 poses. I have been using them some 

 months. Line with white oilcloth a box 

 the size you wish the tray. I am using 

 old plate boxes for rinsing trays. For 

 developer use smaller boxes. Tack the oil- 

 cloth all around on the top of the sides and 

 ends. Fit the oilcloth down in the corners 

 nicely before tacking and it will stay all 

 right. Do not tack it down in the bottom 

 nor cut the corners down any, as then it 

 will leak. I got 2 yards of white oilcloth 

 and have made 5 large trays and a number 

 of small ones at a cost of 50 cents for the 

 lot. I need some large trays as some of 

 my prints are 7 by 15 inches. 



Do any readers of Recreation care to 

 exchange views? I can furnish some fine 

 mountain views, mining scenes, etc. I wish 

 to get a collection of views if I can.
