Scale of photograph formula

WebThe scale of a photograph (S) can also be expressed as the ratio between the focal length of the camera (f) and the altitude of the platform aircraft (H) in the equation S = H/f WebOk a blueprint example. Lets say 1 inch on the drawing is the same as 2 feet in the real world. So, what's the area of a room that is on the drawing 6 inches by 5 inches. Well convert to the real world area first, so 6 inches = 12 feet and 5 inches = 10 feet. Multiply 12 by 10 and the area of the room is 120 square feet.
