detail without any hardness, provided the plate 

 has been properly exposed. 



It should be made up in two solutions, as then 

 it will keep longer than when made in one. A 

 good formula is as follows: No. I. Water, 16 

 ounces ; metol, \ ounce ; when thoroughly dis- 

 solved, add 2\ ounces sulphite of soda, crystals. 

 No. 2. Water, 16 ounces ; carbonate of potassium, 

 \\ ounces; bromide of potassium, 10 grains. For 

 a normal exposure take i ounce of No. i, \ ounce 

 of No. 2, and add i \ ounces of water. In dealing 

 with over exposure the amount of No. 2 should 

 be decreased and a slightly larger amount of No. I 

 used with a few drops of a ten per cent solution 

 of bromide potassium added. For under exposure 

 use \ ounce of No. i, \ ounce of No. 2, and \\ 

 ounces of water. 



The characteristics of a metol-developed nega- 

 tive are softness and " thinness " ; in other words, it 

 is hard to get density. The development should 

 always be carried much farther than what looks, 

 by transmitted light, to be correct, for the density 

 loses considerably in fixing. With pyro it loses 

 but little, and therefore the development, when 

 using pyro, should be carried but little beyond 

 what seems to be the proper density for the fin- 

 ished negative. 



This question of how far to carry a negative in 

 development is one that everybody must learn for
