matter of including all of the subject or ground area in the  picture. Hand-held  oblique  aerial  photography  often provides a unique communication capability—an overall view that cannot be obtained from the ground in a single photograph or even in several photographs. Generally, aerial oblique photos show relationships in size and spacing between objects better than ground views. The angle of view is unusual and attention getting,  partly  because  people  are  unaccustomed  to seeing subjects from above. As with composition for any type of photography, when you compose an aerial photograph, you should consider all the aspects of good composition—image  size,  subject  placement  within  the picture area, balance, camera angle, lighting, and timing (when to fire the shutter). The target and purpose of the pictures are the guides you should use for determining proper   composition.   Good   aerial   photographic composition   is   harder   to   achieve   than   ground photographic composition. In aerial work you are in a moving aircraft and do not have the time necessary to compose  a  picture  in  the  viewfinder.  You  must compose the picture in your mind as you observe the target from the aircraft during the approach. You cannot move the subject around or change the direction from which the light is coming. Your two primary tools in aerial  composition  are  camera  viewpoint  and  timing. You must shoot your pictures at the correct instant to ensure the area and objects of interest are in the picture. Also,  in  a  sequence  of  exposures  (a  strip),  each photograph must have the correct relationship to the 4-28 Figure 4-23.—Hand signals.
