20 PHOTOGRAPHING FLOWERS 



applied, to restrain over-exposure on the green and the 

 yellow. It is almost useless to try to obtain satisfactory 

 pictures of red flowers in a weak light, even with long 

 exposures, and it is a well-known rule that length of 

 exposure does not present an equivalent for brilliancy of 

 light. 



Combinations of red and white flowers are almost im- 

 possible, photographically, for the exposure necessary to 

 get any sort of detail on the red will almost fatally over- 

 expose the lighter hues. If it must be done, try to light 

 the reds locally, as before directed, and in development 

 work for restraint. The formula given by Cramer as 

 " Bromo-Hydrochinon," is most excellent for this work, 

 and, indeed, for all over-exposures. 



-g I : Distilled or ice water, 25 ounces ; 



H d''°'h°" sulphite of sodium (pure, crystals), 3 



inyarocnmon Qujj^gg . hydrochinon, ]^ ounce ; bromide 

 of potassium, ]^ ounce. II : Distilled or ice water, 25 

 ounces ; carbonate of sOda (dry), 3 ounces. 



For use, take equal parts of I and II. Use full strength ; 

 and if there is any reason to suspect ten or more times a 

 normal exposure, start with used developer, or with half 

 the quantity of II. 



For ordinary work I believe in and use the following : 



jj . . (Dissolve in order given. ) I: Distilled" 



niversa ^^ j^^ water, 24 ounces ; metol, i drachm ; 



eve oper. eikonogen, i drachm ; hydrochinon, i 



drachm ; sulphite of sodium (pure, crystals), 2^ ounces ; 



citric acid, 15 grains ; bromide of potassium, 5 grains. 



Dissolve with the aid of gentle heat ; leave stand a half 



day after solution is apparently complete, and filter into 



8-ounce bottles. II: Distilled or ice water, 12)^ ounces ; 



carbonate of soda (dry), % ounce. 



For use take \y^ ounces of I, %. ounce of II and 2 

 ounces of water, using a few drops of 10 per cent bromide 

 solution if plates do not work clear. In summer, increase 

 quantity of water as needed ; and for over-exposure, use 

 less II and more bromide. The used developer- may 

 w*ll be kept in a full bottle, tightly corked, and is excel- 

 lent for starting development. 



With normal exposure, and in a temperature of 70 

 degrees Fahr. , the image should begin to appear in from 

 45 to 60 seconds, and development may be continued five 

 minutes or more. Detail may be coaxed out by the use of 

 fresh developer, diluted with four times its bulk of water. 

 A few trials will soon" show the proper point to which to 

 carry development. The "Bromo-Hydrochinon" may 

 be applied for a nioment to gain density, if necessary.
