Piltdown man, the camera angle can be deceiving at times, long lenses can distort the perspective markedly
I have taken quite a bit of air to air filming and in the right light and lens you can make the aircraft appear at almost ground level. Indeed one picture that was taken at over 2000' agl we discussed as to whether we should let it go public as it had the appearance of something way under 100' and thus might invoke subsequent questioning from the regulator.
