Drying. After the prints are carefully washed they may be surface dried by placing between clean white blotters, then laid out on dry blotters, face side up, until they become surface dry, when they may be placed between cardboard and put under weight until bone dry.
Trimming And Mounting. See following chapter.
Papers To Use. For the beginner we would advise the use of the matt surface bromide paper, as this surface of paper is suited to a large variety of negatives. For further information regarding papers and advanced bromide enlarging, sepia tones, etc., see Volume V.
Notes. Bromide paper must be placed in the paper holder in the dark-room, by the light of a suitable lamp. Be sure that the paper holder and negative holder are securely attached to the camera. Should any other light than that passing through the negative and lens reach the bromide paper it would cause a fog over the print.
Always exercise care in loading the holder, and before opening the dark-room door, to see that all your unexposed bromide paper is returned to its envelope, where it is fully protected from the light.
Bromide paper should be kept in a cool, dry place, away from strong light.
Judging The Face Side Of Paper. The face of bromide paper can always be distinguished by its curling in; the convex side is always the back.
Fog. Fog may be caused by exposing the paper to unsafe light, or by using too little bromide of potassium. The amount given in formula is the minimum that should be used; owing to varied conditions an increased amount may at times be found necessary.
590. Gray prints are caused by under-exposure and forced development.
591. Greenish tones are caused by over-exposure and too much bromide.
593. Complete instruction for bromide enlarging and advanced methods will be found in Volume V.
