Printing-out paper, popularly known as P.O. P., 

 does not show microscopic objects to the best 

 advantage. It is extremely useful for taking trial 

 prints, however, and it is also in great favour with 

 amateur photographers, who consider it the easiest 

 process. A few words, therefore, about it will 

 not be out of place. It is never permanent, and 

 although volumes are written about toning and 

 fixing in separate processes, much trouble will be 

 saved by adopting a single solution for both fixing 

 and toning. The great advantage of this paper is 

 that the result can be seen and printing stopped 

 at the right moment. 



The paper is laid on the negative, glossy side of 

 paper in contact with film side of negative, and 

 placed in a printing frame for exposure to day- 

 light, though not to direct sunlight, unless with 

 very dense negatives. The print should be slightly 

 darker than the finished print is intended to be, 

 owing to loss of colour in fixing.
