difference  in  uncorrected  and  corrected  vertical distortion. ARCHITECTURAL PHOTOGRAPHY Architectural  photography  are  pictures  of  man- made structures, especially buildings. These pictures may be made for planning, construction progress, illustrative purposes, inspection and survey, and other similar  purposes. PLANNING PHOTOGRAPHY Architectural pictures made for planning purposes may fall into several categories. For example, the civil engineer working with an architect on design plans for a new commissary store at the naval air station may need a picture of the commissary store at the naval shipyard to show the architect the general concept of how the new store is to look The engineer may also need the same picture  plus  pictures  of  other  buildings  near  the proposed construction site to be included in the contract bids.  These  planning  pictures  may  have  to  show obstructions to heavy equipment, or where the new store will be located in relation to other buildings, proposed and existing. The architectural pictures you make may be presented to the U.S. Congress for allocation of new-construction   funds. CONSTRUCTION PHOTOGRAPHY Construction  progress  architectural  pictures,  (fig. 6-20A and fig. 6-20B) or simply construction progress pictures, are used as proof of construction progress from architect-to-builder-to-Navy.  Whenever  buildings  or facilities are being built, a photographic record of the project should be made. These pictures may show whether  the  contractor  did  or  did  not  follow specifications as written in the contract. They can also serve  as  a  visual  record  of  the  material  used  in construction.  In  addition  to  their  normal  preservation  as part of the construction contract record, they form the basis for periodic reports to higher echelons, including Congressional  Armed  Services  Committees.  Some  of these pictures may be of great historical value, but their most important function is to serve as documentation for construction  work For a complete record, pictures must be taken at intervals   throughout   the   construction   period. Excavation, foundation work, and the roughing-in process progress slowly; pictures made every 7 to 14 days, starting at day one, may be adequate to show this phase of the work. The rest of the work may go more quickly and require pictures every day or so. For  an  accurate  record  of  construction,  the  pictures are usually made from the same camera position from day to day. However, as construction progresses, it may be necessary to make additional views, both exterior and interior. The   person   for   whom   you   are   doing   the photography should explain any special effect desired in the pictures; for example, accenting structural texture, highlighting a specific construction detail, pinpointing an  architectural  feature,  or  concentrating  on  an exceptional  landscape  view.  And  do  not  forget  to  make the last picture-the one that shows the completed project. We do not mean the one made the day the contractor removed his last hammer from the jobsite. Of course, you made that picture. We mean take a picture several  months  after  the  project  is  “finished,”  when  the grass is green and the trees are planted. The   same   care   you   give   to   other   types   of photography should be given to construction progress photography. Do use good composition and lighting techniques   and   other   similar   applications   of professional photographic skill. Take particular care with  shadow  areas  that  may  contain  important  details. ILLUSTRATIVE    PHOTOGRAPHY The  uses  of  illustrative  architectural  pictures  in  the Navy vary greatly. The commanding officer may want pictures  that  concentrate  on  overall  design  to  show  at  a meeting  with  the  admiral.  The  civil  engineer  may  want pictures that show functional aspects of a building to be included in a report, and the operations officer may want a picture of the operations building, crash and rescue fire house, and the control tower to decorate his office. The editor  of  the  station  paper  may  need  pictures  that  show a building before and after a self-help project. And, of course, the publisher of Welcome Aboard wants a picture of the BEQ and the mess hall. All these pictures are considered  illustrative  architectural  photography  and should be made to show the buildings to best advantage. This type of photography is best done with a view camera  so  horizontal  and  vertical  distortion  can  be overcome  as  much  as  possible.  When  making  this  type of picture, be sure there are no distracting elements in the picture area. The foreground and background should be clean. When possible, have all the windows and doors the same; for example, the windows should all be open or closed and the same for doors. When the windows 6-34
