GENERAL NOTES 129 



Somewhat recently we have from Germany 

 an intensifying medium, which is sold in a 

 concentrated form under the name of "Agfa." 

 A dilute solution having been made as per 

 accompanying directions, the plate to be 

 intensified is simply soaked therein until the 

 required degree of density is reached, which 

 may be noted as that process advances, after 

 which washing and drying succeed each other 

 as before. The resulting negative is of an 

 agreeable brownish color and excellent print- 

 ing qualities, whilst its permanence is said 

 to be unquestionable. I have used Agfa with 

 great satisfaction, but have seen nothing in 

 it to tempt abandonment of the silver cyanide 

 intensifier. Of course both methods are 

 equally applicable to the rather frequent 

 cases of under-development of properly ex- 

 posed plates, or those which have been oven 

 timed as described. 



Reducing Density. It not infrequently hap^ 

 pens, from some cause, generally over-devel- 

 opment of a fully exposed plate, that the 

 negative is too dense for printing. If it be 

 otherwise right, reduction of the over-density 

 may enable us to utilize it with good results. 

 This is generally effected by immersion in
