I should have known better amd explained it earlier since I'm a professional photographer.
When one does an extreme Macro shot, especially those by the non-professional, it's very easy to have the subject and the camera
not align (parallel) to begin with.
So a little bit of distortion from the camera, a little bit of taper end from the second hand and the light/shadow playing tricks,
one might have an image that seems far from the reality.
Allen shows us exactly what might just have happened.
I'm extremely impress with Allen's gentleman mannerism and his patience.
Thanks Allen 
Cheers,
CL
