Photography of the Earth onto tangent and tilted planes and its transformation to panoramic photographs from an external exposure station, if done mathematically, is useful for interpreting the photos taken by a camera mounted on a space vehicle located anywhere in space and pointed towards any part of the Earth. General formulas for vertical and oblique photographs have been established which will be used to find the panoramic coordinates for different points on the Earth. Inverse formulas of transformation are included. A numerical example is given
