    directly overhead with a camera with a depth of 12cm.In the photo the
    span of the plane was same.Can you tell how higher was the plane when
    it was snapped?

    I think there is a problem with your English:

    I think you mean it was photographed with a camera with a lense of focal length 12cm, and the span of the image of the plane was also 12 cm.
