A tilted photograph is obtained with a camera with a focal length equal to 6in (152.4mm) from a flight height above the Datum equal to 8,200ft. The tilt angle is 2˚30 ’and the swing angle is 218˚. Point A has an elevation above the datum equal to 1,435ft and point B has an elevation above the datum equal to 1,587ft. The photo coordinates in A are as follows are in x equal to -2.85in and in y equal to 3.43in. The photo coordinates in B are as follows are in x equal to 3.89in and in y equal to -1.78in. Calculate the Earth coordinates of points A and B and the Earth length AB.

In order for a film camera with a fixed focal length F to focus on anobject located a distance x from the lens, the lens must be a distance yfrom the film. F, y, and x are related as follows: Now suppose a camera has a lens with focal length F = 65. Explain what happens to the distance between the lens and the film as the object moves far away from the lens. When an object far away (x...
