(a) High oblique photographs are those taken at an angle raised from

a partial third dimension by giving the side and top view of the object

(b) The low oblique is similar to the high oblique except that it
does not show the horizon. This is accomplished by taking the photograph at
an angle less than 30 from the perpendicular to the line of flight (Figure
Low Oblique Photo.
