Camera Pointing Angle

Camera pointing angle is the angle below the

horizon.

In a Cessna 182 or Cessna 172 with a photo

window it is not possible to get a pointing

angle much greater than 45 degrees. Smaller

angles result in the photos being greater in

extent perpendicular to the direction of flight

and thus lower resolution at ground-level.

Haze also becomes more significant at smaller pointing angles. 45 degrees is an excellent

choice although 30 degrees is a reasonable compromise.

Setting Camera Pointing Angle

Taking photos with a consistent pointing angle requires the use of a monopod. The

following pictures show how one squadron sets the pointing angle using a locally

fabricated guide. The guide shown is for 45 degrees.
