This imposing building that now houses the Museo de las Casas Reales (Museum of the Royal Houses) was built between 1503 and 1520 and served as the siege of the government of the colony. It is located some 200 meters/yards North of the Cathedral.

I am not sure if I would post it if its preparation hadn't been so hard. I had to show you the result of all that work that is also my first panorama with buildings.

I made more than 20 shots, moving twice along an imaginary line parallel to the building. There were many things that clearly would render things much more complicated than the common stitch: I hadn't a tripod with me (I was too lazy to carry it), I couldn't shoot too far away from the façade because there was a wall behind me, so I had to use a upwards POV that made the verticals converge much, the sun kept appearing and disappearing and I couldn't shoot perpendicularly the right end because the street was even narrower on that side.

I used 9 shots to make the stitch. In all of them I corrected the best I could the distortions resulting from the lenses (barrel) and the low POV (perspective). In some of them, notably the last two of the right, the corrections were particularly tricky because besides the "vertical" distortion, there was also an "horizontal" one. Correcting the perspective isn't an easy task in a "stand alone" photo (at least for me), but the fact that one can leave the "vertical" lines on the sides a little convergent without compromising the natural appearance makes things easier. In a stitch, such minor flaws are disastrous, resulting in what you see: some doors and windows appear as rectangles inclined to one side, others as straight trapezoids, and so on. The exposure and colour balance was also a nightmare. Finally, I had to make several tries to find a reasonable compromise between the compression level and the total number of pixels that fitted the TE limits.

Compared to this one, the landscape panoramas I did so far were a piece of cake.
