What size is the target (subject)? At what time of day is the lighting best? From what direction should the pictures be taken? From  approximately  what  altitude  should  the pictures be taken? What hazards to safe flight are present in the target area? When the photographer and the pilot have the answers   to   these   questions   and   understand   the objectives of the mission, both are in a position to produce quality photographs that meet the needs of the requester. To enable the photographer to take pictures, the pilot must know specific details about the mission. When taking photographs on the ground, you can choose to move either the object or yourself to get proper composition for your pictures. However, in the air, you must rely on the pilot for the desired camera angle and the correct camera-to-subject distance. The pilot cannot read your mind, so it is important to discuss your plans in detail before the flight. Remember, there is not time to accomplish this while you are both in flight. Other reasons for discussing plans before the flight are as follows: the mission may require maneuvers the aircraft is incapable of performing or the pilot may perform a different maneuver to get the same results. On the ground, the photographer has sole control over the camera. In the air, the camera is, so to speak, in the hands of both the photographer and the pilot. Both must coordinate their efforts and work together as a team. MAPS AND CHARTS For some aerial assignments, a map or chart is important for the successful accomplishment of an aerial  photographic  mission.  You  should  become familiar with the different types of maps and charts available. A map is used primarily for land navigation, while a chart is used primarily for water navigation. Represented  on  a  map  or  chart  are  the  essential topographic features, such as water depths, roads, railroads,  rivers,  lakes,  towns,  cities,  airfields,  and  other man-made objects. The scale of a map or chart depends upon personal choice  and  availability.  A  large-scale  map  provides greater detail, while a small-scale map covers a larger area. The scale of the map you use should be large enough to define the target clearly yet small enough to include a large area surrounding the target. Reading a map is easier when the top of the map is forward, so the map lies in front of you, just as the ground does. You may find the map easier to use during the flight when you write on it, so the top is in the main direction of flight. Once you have located the target on the map, you should mark it. Indicate the type of photograph and any other information that may be of assistance  in  your  photographic  mission,  such  as altitude, scale, and angle. Geometric North should also be marked on the map. WEATHER Temperature inversion in the atmosphere tends to concentrate and trap particles in the air, causing haze. A common type of temperature inversion may be characterized by smoke that rises to a certain height, Figure 4-11.—Characteristic of temperature inversion. 4-11
