CHAPTER 8 COPYING The term copying, as used in photography, means producing a photograph from a photograph, map, painting, or similar flat document. A document that is copied is called the “copy original” or “original,” and the  products  of  the  copying  process  are  called “reproductions*’  or  “copies.”  Originals  are  broadly classed  as  reflection  originals  and  transparent  originals. The photographic reproduction can be any size in relation  to  the  original  document. Copying is a large and important part of naval photography. It provides an important service to most every  aspect  of  the  Navy-from  the  Intelligence Specialist giving a training lecture, to the admiral who needs 100 copies of a map for planning an invasion. Photographic copying is an accurate, inexpensive, and  quick  way  of  reproducing  originals.  Copying  is skilled work and you must give it the same careful attention that you give to other types of photography. Making   good   photographic   copies   is   an accomplishment any photographer can be proud of. A knowledge of copying techniques extends your skill as a Navy photographer and makes you more useful to yourself and the Navy. The process of copying is complicated by the extensive  variation  in  the  type  of  originals  to  be  copied and the varying conditions under which the work is done. The materials to be copied range from simple line drawings to transparencies that are used daily aboard ship  and  at  shore  stations.  Films  used  for  copy photography are processed much the same as films for other photography. They can be processed by hand, in trays and tanks, or processed by machine. COPY   TERMINOLOGY Copying–Photographing  flat  documents,  such  as photographs,  drawings,  blueprints,  charts,  and  so forth. Original–Material from which copies are made, such as handwritten copy, typed copy, printed matter, tracings, drawings, and photographs. Halftone–Reproduction by printing processes, such as lithography  of  a  photograph  in  which  the  gradation of tone is reproduced by a pattern of dots and intermittent white spaces, caused by interposing a halftone  screen  between  the  lens  and  the  film.  (See fig. 8-1.)
