opinion, by far the best developer for general 

 work. 



There are many other developers on the market, 

 all good, but it is unnecessary to enumerate them 

 here. 



We should always have a bottle of a ten per 

 cent solution of bromide of potassium in the dark 

 room for use in cases of over exposure, for a few 

 drops added to any developer acts as a retarder. 



In development we should always watch the 

 negative carefully. It is well to have two strengths 

 of developer mixed ready for use, one normal and 

 the other much weaker. Commence development 

 with the weak solution, and if the image appears 

 too quickly and has a tendency toward " flatness," 

 then the plate has been overexposed and must be 

 treated accordingly by using the normal developer 

 with some of the bromide solution added to it. If 

 the image, on the other hand, comes up very 

 slowly and has the appearance of being spotty 

 and " hard," then it has been underexposed and 

 the developer must be weakened still more and no 

 bromide added. This will bring out what detail 

 there may be in the plate, but, of course, if it has 

 been very badly underexposed, nothing can be 

 done with it. 



If we know that a plate is very badly over- 

 exposed, before we commence development, it can 

 often be saved by first soaking it in water to which
