Is it straight? Yes (Horizontal) / No

[bhuniatrekearth]

Dear Renier,
Excellent illusion: there in your capture. I am sure you have already noticed it and carefully adhered only to the horizontal line definition.

Ms. Katia (tigra) has been misled by the illusion and advised for a straightening. Mr. Simon (sadeik) has carefully noticed it and mentioned.

The horizontal lines are perfect regarding the straightening of the picture.
But vertical line consideration shows that the top of the frame is tilted to the right.

Mr. Simon has blamed the camera angle for the problem.
There may be another reason that is an ill aligned construction of the building.
I have withdrawn myself from a workshop detecting this phenomenon.

Hello Dr. J,
I took this shot in an angle and maybe that answers the illusion. I tried adjusting the tilt but in doing so the lines at the top eaves does not look aligned. In the end I decided to use the top line as the reference and tried to blur surrounding verticsl references. Thanks for taking interest and viewing the photo.
Regards,
Renier
